1. Acacia farnesiana (tree, shrub) English  français     
Probably a native of tropical America, Acacia farnesiana was introduced to many tropical countries for its bark, gum, seed and wood. It is often planted as an ornamental or to check erosion, and is also used in the perfume industry because of its scented flowers. This thorny, deciduous shrub grows to 4m in height forming impenetrable thickets or sometimes a more open cover and prefers dry habitats between sea level and 1000 m. In Australia it occurs along watercourses on rangeland and farmland limiting access to water. It has also become an invasive species in Fiji, French Polynesia, New Caledonia, Solomon Islands, and Vanuatu.

2. Acacia mearnsii (tree, shrub) English  français     
Acacia mearnsii is a fast growing leguminous (nitrogen fixing) tree. Native to Australia, it is often used as a commercial source of tannin or a source of fire wood for local communities. It threatens native habitats by competing with indigenous vegetation, replacing grass communities, reducing native biodiversity and increasing water loss from riparian zones.
Common Names: acácia-negra, Australian acacia, Australische akazie, black wattle, swartwattel, uwatela
Synonyms: A. decurrens var. mollis, Acacia mollissima
3. Acacia melanoxylon (tree) English  français     
Acacia melanoxylon is native in eastern Australia. This tree grows fast and tall, up to 45m height. It has a wide ecological tolerance, occurring over an extensive range of soils and climatic conditions, but develops better in colder climates. Control of its invasion of natural vegetation, commercial timber plantations and farmland incurs considerable costs, but its timber value and nursing of natural forest succession provides a positive contribution.
Common Names: acacia à bois noir, acacia de madera negra, acacia rouge, acácia-preta, algarrobo, aroma salvaje, Australian blackwood, Australiese swarthout, blackwood, blackwood acacia, Tasmanian blackwood
Synonyms: Racosperma melanoxylon (R.Br.) C.Martius

10. Ailanthus altissima (tree, shrub) English     
Ailanthus altissima is a very aggressive plant, a prolific seed producer (up to 350,000 seeds in a year), grows rapidly, and can overrun native vegetation. It also produces toxins that prevent the establishment of other plant species. The root system is aggressive enough to cause damage to sewers and foundations.
Common Names: Chinese sumac, stinking shumac, tree-of-heaven
11. Alternanthera philoxeroides (aquatic plant, herb) English     
Alternanthera philoxeroides, commonly known as alligator weed, is a perennial stoloniferous herb that can be found in many parts of the world, infesting rivers, lakes, ponds and irrigation canals, as well as many terrestrial habitats. The aquatic form of the plant has the potential to become a serious threat to waterways, agriculture and the environment. The terrestrial form of Alternanthera philoxeroides grows into a dense mat with a massive underground rhizomatous root system. The canopy can smother most other herbaceous plant species. It has proven to be extremely expensive to attempt controlling Alternanthera philoxeroides.

12. Ambrosia artemisiifolia (herb) English     
Ambrosia artemisiifolia is a summer annual herbaceous plant that is native to temperate North America in the United States and Canada. Also commonly known as ragweed this forb establishes easily in human impacted and disturbed areas in high abundance. It is considered an invasive species in Europe, parts of Asia and Australia, although it is not an extremely competitively aggressive species and is mainly considered a noxious weed that interferes with other cultivated crops. The main impact of this plant is the copious amount of pollen produced from male flowers that are allergens to sensitive people, compounding health problems like rhinitis, oculorhinitis, asthma and causing skin irritations.

15. Anoplophora glabripennis (insect) English     
  See eradication or other absence information
The Asian longhorn beetle Anoplophora glabripennis is a large wood-boring beetle that is native to countries in Asia, such as Japan, Korea and China. The beetle spends most of its life within the inner wood of a variety of hardwood trees as larvae which tunnel and feed on the cambium layer, eventually killing the tree. It was first detected in New York 1996, although it is thought to have arrived in the 1980s in solid wood packing material from China. It has since been detected in Massachusetts, New Jersey, Illinois, California, Ontario (Canada) and parts of Europe. The Asian longhorn beetle threatens 30-35% of the trees in urban areas of eastern USA. The economic, ecological and aesthetic impacts on the United States would be devastating if the beetle continues to spread. Potential losses have been estimated in the tens to hundreds of billions of US dollars. Current control measures focus on rapidly delimiting new infestations, imposing quarantine and cutting down and burning of infected trees.
Common Names: ALB, Asian longhorn beetle, Asian longhorned beetle, Asiatischer Laubholzkäfer, longicorne Asiatique, starry sky beetle
Synonyms: Anoplophora nobilis
16. Aphanomyces astaci (oomycete) English     
Aphanomyces astaci commonly referred to as crayfish plague is an oomycete or water mould that infects only crayfish species. It is endemic of North America and is carried by North American crayfish species; signal crayfish Pacifastacus leniusculus, Procambarus clarkii and Orconectes limosus. A. astaci was introduced into Europe through imports of North American species of crayfish. Native European crayfish populations are not resistant to this oomycete. It has since devastated native crayfish stocks throughout the continent.
Common Names: crayfish plague, Wasserschimmel
17. Arundo donax (grass) English  français     
Giant reed (Arundo donax) invades riparian areas, altering the hydrology, nutrient cycling and fire regime and displacing native species. Long ‘lag times’ between introduction and development of negative impacts are documented in some invasive species; the development of giant reed as a serious problem in California may have taken more than 400 years. The opportunity to control this weed before it becomes a problem should be taken as once established it becomes difficult to control.

20. Branta canadensis (bird)
Branta canadensis, Canada geese are very adaptable. They can live in a broad range of habitats, which includes cohabitation with humans. In addition, Canada geese are highly fecund and lacking in amount of predators. Population growth of this species over the past years has caused problems in many different areas including environmental, aesthetic, and human health. Canada geese can either be migratory or resident, which enables them to occupy a large geographical range. This species has created issues not only in areas where it has been introduced, but also in its native locations due to the population explosion of the species. Although this species has created problems, it also has been of economic use as well as being, at times, an enjoyable aspect of wildlife.

  See eradication or other absence information
Castor canadensis (beaver) is native to North America, and has been introduced to Tierra del Fuego in southern South America, Finland, France, Poland and Russia in recent times. In its introduced range, the damming activity of the beaver can cause flooding which can damage forests. They also have the ability to quickly cut down large numbers of trees. In Finland, they compete with native beaver populations. In their native range, they cause flooding on major highways by plugging highway culverts.
Common Names: American beaver, beaver, Canadian beaver, castor, castor americano, North American beaver
26. Caulerpa taxifolia (alga) English     
Caulerpa taxifolia is an invasive marine alga that is widely used as a decorative plant in aquaria. A cold-tolerant strain was inadvertently introduced into the Mediterranean Sea in wastewater from the Oceanographic Museum at Monaco, where it has now spread over more than 13,000 hectares of seabed. Caulerpa taxifolia forms dense monocultures that prevent the establishment of native seaweeds and excludes almost all marine life, affecting the livelihoods of local fishermen.
Common Names: caulerpa, killer alga, lukay-lukay, Schlauchalge, sea weed
Synonyms: Fucus taxifolius Vahl, 1802
27. Cenchrus echinatus (grass)
         Interim profile, incomplete information
Cenchrus echinatus is an annual grass that is a native of tropical America, but has now widely colonised tropical and temperate zones worldwide. Though it is typically associated with dry, sandy habitats it can also grow in moist areas, where it may be long-lived and reach a much larger size. It is recognisable by the burrs it produces, which readily attach themselves to animals and clothing, making C. echinatus easily dispersed. It is fairly easily managed by physical and chemical means, though the soil seed reservoir means followup treatments are necessary.

28. Ceratitis capitata (insect) English  français 
Ceratitis capitata is considered a major tephritid fruit fly pest of economic importance attacking more than 300 different hosts, primarily temperate and subtropical fruits. The medfly as it is commonly called has invaded many countries and caused major economic losses for fruit farmers. C. capitata has the ability to tolerate cooler climates better than most other species of fruit flies. It lays its eggs under the skin of fruit, usually around already broken skin. Due to this reproduction habit, C. capitata thrives in agricultural areas where fruit is left out and becomes damaged. It spreads to new locations via exports and the local sale of fruit that contains eggs.
Common Names: medfly, Mediterranean fruit fly
Synonyms: Ceratitis citriperda MacLeay , Ceratitis hispanica De Brême, Paradalaspis asparagi Bezzi, Tephritis capitata Wiedemann , Trypeta capitata Wiedemann, 1824

40. Crassula helmsii (aquatic plant, succulent)
Crassula helmsii is a macrophyte native to Australia and New Zealand. It has become an especially problematic invasive in the United Kingdom and has established troublesome populations throughout western Europe and in southeastern United States. It establishes dense, floating or submerged populations that displace native aquatic plants, decrease biodiversity, alter water conditions, and harm the asethetic and recreational of bodies of water. It rapidly spreads and recolonizes via vegetative reproductions from plant fragments.
Common Names: Australian stonecrop, Australian swamp stonecrop, Crassule des étangs, Helms Dickblatt, New Zealand pygmyweed, swamp stonecrop, Watercrassula
Synonyms: Bulliarda recurva (Hook. f.), Crassula recurva (Hook. f.) Ostenf., Tillaea helmsii Kirk, Tillaea recurva (J.D. Hook.)
41. Crepidula fornicata (mollusc) English   
Crepidula fornicata is a protandrous hermaphrodite mollusc, which means that the animals start their lives as males and then subsequently may change sex and develop into females. This species can tolerate a wide range of environmental conditions. Populations are particularly well developed in wave-protected areas such as bays, estuaries or sheltered sides of wave-exposed islands. C. fornicata competes with other filter-feeding invertebrates for food and space, and often occur in enormous numbers. Few management options are available to combat this species. Dredging operations to clear slipper limpets from oyster beds have been attempted in some areas, but it was concluded that further spread of the species could not be prevented.
Common Names: American limpet, common Atlantic slippersnail, crépidule, oyster-pest, Pantoffelsnecke, slipper limpet, Toffelsneg
Synonyms: Crepidula densata Conrad, Crepidula maculata Rigacci, Crepidula mexicana Rigacci, Crepidula nautiloides auct. non Lesson, Crepidula roseae Petuch, Crepidula violacea Rigacci, Crepidula virginica Conrad, Crypta nautarum Mörch, Patella fornicata Linné
42. Cryphonectria parasitica (fungus) English     
Cryphonectria parasitica is a fungus that attacks primarily Castanea spp. but also has been known to cause damage to various Quercus spp. along with other species of hardwood trees. American chestnut, C. dentata, was a dominant overstorey species in United States forests, but now they have been completely replaced within the ecosystem. C. dentata still exists in the forests but only within the understorey as sprout shoots from the root system of chestnuts killed by the blight years ago. A virus that attacks this fungus appears to be the best hope for the future of Castanea spp., and current research is focused primarily on this virus and variants of it for biological control. Chestnut blight only infects the above-ground parts of trees, causing cankers that enlarge, girdle and kill branches and trunks.
Common Names: chestnut blight, Edelkastanienkrebs
Synonyms: Endothia parasitica
43. Cryptococcus fagisuga
The beech scale insect (Cryptococcus fagisuga), along with Neonectria ascomycete fungi form the disease-complex responsible for beech bark disease (BBD) of American and European beech. Beech scale infests mainly larger sized beech trees, feeding on host tissues and causing small fissures on the bark. This initial damage to the tree allows Neonectria to enter the tree, which kills host tissue and eventually girdles the tree causing it to die. In North America the main fungi involved are N. faginata and N. ditissima, whereas in Europe N. ditissima and N. coccinea are responsible for the disease. BBD can dramatically alter forest stand composition and structure, through loss of large trees and proliferation of smaller trees that originate from root sprouting. Reduction of beech nut production and loss of large trees in infected stands may affect mammals and birds that use beech nuts as important food source and old trees as habitat. Around 1% of American beech is estimated to be resistant to BBD. Research is currently focused on modes of inheritance and propagation methods.
Common Names: beech scale, beech scale insect, felted beech coccus, felted beech scale, woolly beech scale, woolly beech scale insect
Synonyms: Cryptococcus fagi Baer.
44. Ctenopharyngodon idella (fish) English   
Grass carp (Ctenopharyngodon idella) is a large cyprinid introduced worldwide as a biological control of aquatic vegetation as well as a food fish. It is a voracious feeder which is incredibly efficient at removing aquatic weeds. However they can completely eliminate vegetation from water systems, resulting in widespread ecological effects. Grass carp are also known to compete with native fish, carry parasites such as Asian tapeworm (Bothriocephalus opsarichthydis), and induce other harmful effects to introduced waters.

47. Diaphorina citri (insect)
Diaphorina citri or Asian citrus psyllid is one of the most serious pests of citrus in the world. It causes damage through direct feeding and its toxic saliva, leading to leaf distortion and curling in young tender growth. In addition the copious amounts of honeydew it excretes causes sooty molds to grow which blemish leaves and reduce photosynthesis. However it is the ability of D. citri to vector the Asian and American forms of the huanglongbing (HLB) disease which makes this so damaging. HLB is caused by phloem-restricted bacteria in the genus Candidatus Liberibacter. HLB causes chlorosis resembling zinc deficiency, twig dieback, stunting of growth and reduced fruit size and quality. Trees usually die after several years and entire orchards may be devastated. HLB seriously threatens citrus industries worldwide. At present there are no curative methods for trees infected with the bacteria, so control methods have focused on reducing D. citri populations. Control is achieved through a combination of physical, chemical and biological methods.
Common Names: Asian citrus psyllid, Asiatic citrus psyllid, Citrus psylla, Oriental citrus psyllid, Psilideo de l'aranjeira, Psylle de l'oranger

49. Egeria densa (aquatic plant) English  français     
Egeria densa is a submersed, freshwater perennial herb that forms dense monospecific stands that restrict water movement, trap sediment, and cause fluctuations in water quality. It has also affected the status of certain threatened species. It has been introduced worldwide through the aquarium trade, and even in its native range can become a nuisance species causing local economic impacts. Chemical control is the most effective option for management of E. densa. Mechanical control is not recommended because fragments of the plant left behind can readily re-colonize and move downstream. The introduction of grass carp offers biological control of this species, but care must be taken because carp can introduce their own negative effects on the environment.
Common Names: Brazilian elodea, Brazilian waterweed, Brazilian-waterweed, common waterweed, dense waterweed, egeria, leafy elodea, South American waterweed

Elminius modestus has spread successfully throughout the Western Europe coastal areas, since its introduction to the southeast coast of the Uk most probably on the hull of ships from New Zealand and /or Australia between 1940 and 1943. There are several factors that aid Elminius success as an invader. Elminius larval stages are eurythermal and euryhaline, enabling them to survive in a wide range of habitat types. E. modestus is a highly fecund species and has a short generation time. It is highly tolerant of changes in tempertaure and salinity. E. modestus compete with native barnacle species for space. It has been observed that the successful range expansion of the barnacle could be facilitated by a changing climate with warmer seas and tempertaures.
Common Names: Australian barnacle, Australische Seepocke, Australseepocke, Firepladet rur, Kruisridderpok, New Zealand barnacle, Nieuw-Zeelandse zeepok, Sterretje
Synonyms: Austrominius modestus
51. Elodea canadensis (aquatic plant) English     
Elodea canadensis a submergent, aquatic plant, native to North America, has spread rapidly and easily throughout the world. Particularly in Europe, this species is very invasive and is considered a weed due to its ability to grow and multiply fairly rapidly in many diverse habitats and conditions. It is capable of causing problems of economic importance, habitat alteration, competition and threat to biodiversity. In addition, this species is not easily manageable. For these reasons, this species has been the focus of many experiments and research in the hopes of establishing a greater knowledge of growth habits, the true threat it causes, and possible prevention methods.

52. Equus caballus (mammal)
         Interim profile, incomplete information
Equus caballus is a large non-ruminant herbivorous mammal that is not dissimlar in appearance to the domestic horse. E. caballus has an average lifespan of 25 - 30 years, with 20 years of sexual activity. While preferred habitat is open grasslands, E. caballus has been also known to invade desert, semi-desert plains, coastal areas, subalpine regions, tropical savannah grasslands, forests, scrublands and wetlands. In some regions they are protected as they are seen as a valuable asset, but in other places they are considered a pest, as they compete with livestock for resources, degrade plant habitats by grazing and trampling, contaminate water sources, damage fences and decrease native biodiversity.
Common Names: feral horse, horse
53. Eriocheir sinensis (crustacean) English     
Eriocheir sinensis (the Chinese mitten crab) is a migrating crab which has invaded Europe and North America from its native region of Asia. During its mass migrations it contributes to the temporary local extinction of native invertebrates. It modifies habitats by causing erosion due to its intensive burrowing activity and costs fisheries and aquaculture several hundreds of thousands of dollars per year by consuming bait and trapped fish as well as by damaging gear.

55. Felis catus (mammal) English  français     
Felis catus was domesticated in the eastern Mediterranean c. 3000 years ago. Considering the extent to which cats are valued as pets, it is not surprising that they have since been translocated by humans to almost all parts of the world. Notable predators, cats threaten native birdlife and other fauna, especially on islands where native species have evolved in relative isolation from predators.
Common Names: cat, domestic cat, feral cat, Hauskatze, house cat, poti, pusiniveikau
56. Ficopomatus enigmaticus (annelid)
Ficopomatus enigmaticus is a reef building tubeworm, believed to be native to Australia and regions of the Indian Ocean. It has established populations worldwide and is an aggressive species that dominates habitats, significantly altering water conditions and physical environments resulting in changes to native communities. F. enigmaticus is also an abundant fouling species. It has caused problems in cooling intakes of power plants and is extremely common in harbours and on ships hulls.
Common Names: Australian tubeworm, australsk kalkrørsorm, Tüten-Kalkröhrenwurm
Synonyms: Mercierella enigmatica (Fauvel, 1923)
57. Gambusia affinis (fish) English  français     
Gambusia affinis is a small fish native to the fresh waters of the eastern and southern United States. It has become a pest in many waterways around the world following initial introductions early last century as a biological control agent for mosquitoes. In general, it is considered to be no more effective than native predators of mosquitoes. The highly predatory mosquito fish eats the eggs of economically desirable fish and preys on and endangers rare indigenous fish and invertebrate species. Mosquito fish are difficult to eliminate once established, so the best way to reduce their effects is to control their further spread. One of the main avenues of spread is continued, intentional release by mosquito-control agencies. G. affinis is closely related to he eastern mosquito fish (G. holbrooki), which was formerly classed as a sub-species. Their appearance, behaviour and impacts are almost identical, and they can therefore be treated the same when it comes to management techniques. Records of G. affinis in Australia actually refer to G. holbrooki.

60. Gonipterus scutellatus (insect)
         Interim profile, incomplete information
Gonipterus scutellatus, or the eucalyptus snout beetle, is native to Australia. It is specific to Eucalyptus species, and G. scutellatus is considered to be one of the major defoliators of Eucalyptus spp. worldwide. It causes damage to eucalyptus in both larval and adult stages, in particular to the young leaves and repeated defoliation by G. scutellatus can lead to tree death. However, the egg parasitoid Anaphes nitens has been introduced as a successful biological control agent in several countries.
Common Names: eucalyptus snout beetle, eucalyptus weevil, Eukalyptusrüssler, gorgojo del eucalipto, gum tree weevil
61. Gracilaria vermiculophylla (aquatic plant)
Gracilaria vermiculophylla (Ohmi) Papenfuss is a red alga and was originally described in Japan in 1956 as Gracilariopsis vermiculophylla. It is thought to be native and widespread throughout the Northwest Pacific Ocean. G. vermiculophylla is primarily used as a precursor for agar, which is widely used in the pharmaceutical and food industries. It has been introduced to the East Pacific, the West Atlantic and the East Atlantic, where it rapidly colonises new environments. It is highly tolerant of stresses and can grow in an extremely wide variety of conditions; factors which contribute to its invasiveness. It invades estuarine areas where it outcompetes native algae species and modifies environments.
Synonyms: Gracilaria asiatica Zhang & Xia, Gracilariopsis vermiculophylla Ohmi
62. Gunnera tinctoria (herb) English     
Gunnera tinctoria is a large herbaceous plant that forms dense colonies that shade out and suppress native vegetation. This species is a vigorous seeder, and birds facilitate its spread. Its ability to reproduce rhizomatically is yet another reason for its invasive nature. Intense effort is required to control this species.
Common Names: Chilean gunnera, Chilean rhubarb, giant rhubarb, nalca, panque
Synonyms: Gunnera chilensis Lam., Gunnera scabra (Ruiz.&Pav.), Panke tinctoria Molina (basionym)
63. Gymnocephalus cernuus (fish) English   
Gymnocephalus cernuus is introduced into new locations in the ballast water of ships. Introductions also occur through escaped or discarded live bait. It has become a threat to the Great Lakes in North America and some lakes in Europe. Gymnocephalus cernuus has become invasive due to its reproduction ablity; its wide habitat range and its aggressive feeding habits.
Common Names: blacktail, Eurasian ruffe, pope, redfin darter, river ruffe, ruffe
Synonyms: Acerina cemua (Linnaeus, 1758), Acerina czekanowskii, Acerina fischeri, Acerina vulgaris, Perca cermua Linnaeus, 1758
64. Harmonia axyridis (insect)
Harmonia axyridis (Harlequin ladybird), is native to Asia and has been used extensively around the world for biological control of various aphid species. While it is a popular control agent, it has also brought with it several negative effects. Its establishment appears to decrease the diversity of native Coccinellidae. Harmonia axyridis can also quickly become a human nuisance when it seeks shelter during the winter months and takes up residency in the walls and insulation of houses and other structures. Surprisingly, Harmonia axyridis has also attained status as a pest of fruit production; particularly in the vineyards of the Midwestern USA.
Common Names: Asian lady beetle, Asiatischer Marienkafer, Halloween lady beetle, Harlequin lady beetle, Harlequin ladybird, Japanese lady beetle, la coccinelle asiatique, multicolored Asian lady beetle, multivariate lady beetle, pumpkin lady beetle, southern lady beetle, veelkeurig aziatisch lieveheersbeestje
65. Hemigrapsus sanguineus (crustacean)
Hemigrapsus sanguineus is commonly called the Asian shore crab and is native to the Asia-Pacific region. It has a very broad diet and, in its introduced range, has the potential to affect populations of native species, such as crabs, fish and shellfish by disrupting the food web. It also occupies habitats very similar to native mud crabs. Hemigrapsus sanguineus may compete with larger species, like the blue crab, rock crab and the non-native green crab.
Common Names: Asian shore crab, Japanese shore crab
66. Heracleum mantegazzianum (herb) English     
Heracleum mantegazzianum is native to Asia and has been introduced into Europe and North America. It is characterised by its size and may grow to 4.5 to 6 metres in height. It is most common along roadsides, vacant lots, streams and rivers, and can be considered an invasive freshwater weed. It forms a dense canopy, out-competing native riparian species and results in an increase in soil erosion along the stream banks where it occurs. Heracleum mantegazzianum germinates from early spring throughout the growing season, after exposure to winter temperatures. H. mantegazzianum exudes a clear watery sap that sensitises the skin to ultraviolet radiation which can result in severe burns. Populations in urban and suburban areas represent an increasing public health hazard. Glyphosate is considered the most effective herbicide.

70. Impatiens glandulifera (herb) English     
Impatiens glandulifera, or Himalayan balsam, is a problematic invasive which has spread throughout Europe, parts of North America and New Zealand following introductions as an ornamental. It is an annual herb which thrives in riparian zones and disturbed areas. Its high reproductive rate, early germintation, propensity for establishing thick stands, rich nectar production, hardiness, and habitat tolerance and plasticity have allowed it to spread rapidly, dominate landscapes, and compete with and displace native plant species. Eradication has proven very difficult once established and preventative measures are recommended.
Common Names: balsamie de l'himmalaya, bitine sprige, Drüsiges Springkraut, Himalayan balsam, Indian balsam, Indisches Springkraut, jättebalsamin, jättipalsami, Kæmpe-Balsamin, kjempespringfrø, Niecierpek gruczolowaty, Niecierpek himalajski, ornamental jewelweed, policeman's helmet, puku sprigane, risalísa, verev lemmalts, Washington orchid

71. Imperata cylindrica (grass) English  français     
Native to Asia, cogon grass (Imperata cylindrica) is common in the humid tropics and has spread to the warmer temperate zones worldwide. Cogon grass is considered to be one of the top ten worst weeds in the world. Its extensive rhizome system, adaptation to poor soils, drought tolerance, genetic plasticity and fire adaptability make it a formidable invasive grass. Increases in cogon grass concern ecologists and conservationists because of the fact that this species displaces native plant and animal species and alters fire regimes.
Common Names: alang-alang, blady grass, Blutgras, carrizo, cogon grass, gi, impérata cylindrique, japgrass, kunai, lalang, ngi, paille de dys, paillotte, satintail, speargrass
Synonyms: Imperata arundinacea Cirillo, Lagurus cylindricus L.
72. Lagarosiphon major (aquatic plant) English  français     
Lagarosiphon major is a rhizomatous, perennial, submerged aquatic plant. It can inhabit freshwater lakes, dams and slow-moving streams. Lagarosiphon major can form dense floating mats in deep-water reservoirs and other water bodies and it can block the intakes of hydro-electric systems. Dense growth of Lagarosiphon major can block light penetration into waterways, eliminating growth of native water plants and affecting associated populations of aquatic invertebrates. Lagarosiphon major can also restrict the passage of boats and limit recreational activities like swimming and angling. Storms can tear weed mats loose and deposit large masses of rotting vegetation on beaches, spoiling their amenity value.
Common Names: African elodea, curly waterweed, elodée africaine, Lagarosiphon, lagarosiphon majeur, oxygen weed, South African oxygen weed, submerged onocotyledon
Synonyms: Elodea crispa
73. Lasius neglectus (insect)
Lasius neglectus is a recent arrival in Europe. Some of its populations have attained pest status but on other sites, the ant is still in an arrested state, perhaps in the lag-phase, lacking the major characteristics of invaders. Its negative effects are caused by the enormous numbers of ants tending aphids on trees and occupation of electrical conduits in homes and gardens.
Common Names: invasive garden ant
74. Leuciscus idus (fish) English   
Leuciscus idus (orfe) are a large-bodied freshwater fish native to Europe. They are valued as a sport fish in many countries and have been introduced to a number of locations for this purpose. Concerns have been raised about their potential to damage to native aquatic ecosystems but there seems to be a lack of information regarding any proven effects.

75. Linepithema humile (insect) English     
Linepithema humile (the Argentine ant) invades sub-tropical and temperate regions and is established on six continents. Introduced populations exhibit a different genetic and social makeup that confers a higher level of invasiveness (due to an increase in co-operation between workers in the colony). This allows the formation of fast growing, high density colonies, which place huge pressures on native ecosystems. For example, Linepithema humile is the greatest threat to the survival of various endemic Hawaiian arthropods and displaces native ant species around the world (some of which may be important seed-dispersers or plant-pollinators) resulting in a decrease in ant biodiversity and the disruption of native ecosystems.
Common Names: Argentine ant, Argentinische Ameise, formiga-Argentina
Synonyms: Iridomyrmex humilis (Mayr, 1868)
76. Lithobates catesbeianus (=Rana catesbeiana) (amphibian) English     
The American bullfrog (Lithobates catesbeianus (=Rana catesbeiana)) is native to North America. It has been introduced all over the world to over 40 countries and four continents. Many introductions have been intentional with the purpose of establishing new food sources for human consumption. Other populations have been established from unintentional escapes from bullfrog farms. Consequences of the introduction of non-native amphibians to native herpetofauna can be severe. The American bullfrog has been held responsible for outbreaks of the chytrid fungus found to be responsible for declining amphibian populations in Central America and elsewhere. They are also important predators and competitors of endangered native amphibians and fish. The control of this invasive in Europe partly relies upon increasing awareness, monitoring and education about the dangers of releasing pets into the wild. Strict laws are also in place to prevent further introductions. Eradication is achieved largely by physical means including shooting, spears/gigs, bow and arrow, nets and traps.
Common Names: bullfrog, grenouille taureau, North American bullfrog, Ochsenfrosch, rana toro, Stierkikker
Synonyms: Rana catesbiana Shaw, 1802
77. Lonicera japonica (vine, climber) English  français     
Lonicera japonica is an extremely vigorous vine which grows up through the canopy, smothering and ultimately killing the host tree. It competes with native plants for light and nutrients and prevents the understorey and small trees from developing, causing a reduction in forest diversity. Lonicera japonica is shade and drought tolerant, though it needs full to partial sunlight to grow successfully. It spreads rapidly via above-ground runners that root at nodes and its seeds may be eaten by birds and then dispersed. It is planted in gardens and along roadsides for landscaping purposes and can also be spread by the dumping of garden waste.
Common Names: chèvrefeuille, chèvrefeuille du Japon, Chinese honeysuckle, Hall's honeysuckle, Japanese honeysuckle, Japanisches Geissblatt, madreselva, madressilva
Synonyms: Caprifolium hallianum Hort., Lonicera brachypoda DC., Lonicera flexuosa Thun., Lonicera japonica var. chinensis, Lonicera japonica var. chinensis (P.W. Wats.) Baker, Nintooa japonica , Nintooa japonica (Thunb.) Sweet
78. Macfadyena unguis-cati (vine, climber) English  français     
Macfadyena unguis-cati is a perennial, climbing liana found primarily in tropical forests. It is native to the Central and South Americas and the West Indies, but currently is represented on every continent except Antartica. It is an invasive species in much of its range and is said to be “one of the most destructive exotic vines”. Macfadyena unguis-cati effects all layers of infected forest ecosystems by rapidly spreading both vertically and horizontally across everything with which it makes contact, overwhelming both the understorey plants and the canopy trees. Macfadyena unguis-cati species becomes established quickly and is difficult to eliminate due to its rapid growth, extensive root system, and prolific seed production. Methods of manual, chemical, and biological control for Macfadyena unguis-cati are available.

82. Mus musculus (mammal) English  français     
  See eradication or other absence information
The house mouse (Mus musculus) probably has a world distribution more extensive than any mammal, apart from humans. Its geographic spread has been facilitated by its commensal relationship with humans which extends back at least 8,000 years. They cause considerable damage to human activities by destroying crops and consuming and/or contaminating food supplies intended for human consumption. They are prolific breeders, sometimes erupting and reaching plague proportions. They have also been implicated in the extinction of indigenous species in ecosystems they have invaded and colonised. An important factor in the success of M. musculus is its behavioural plasticity brought about by the decoupling of genetics and behaviour. This enables M. musculus to adapt quickly and to survive and prosper in new environments.
Common Names: biganuelo, field mouse, Hausmaus, house mouse, kiore-iti, raton casero, souris commune, wood mouse
83. Musculista senhousia (mollusc) English

Its ecological effects have yet to be determined.
Common Names: brackish water mussel, Conrad's false mussel, dark false mussel
Synonyms: Congeria cochleata , Congeria cochleatus , Mytilopsis cochleatus , Mytilopsis leucophaeta , Mytilopsis leucophaetus
90. Neovison vison (=Mustela vison) (mammal)
Mustela vison (American mink) is part of the mustelid family (order Carnivora). They live alone along riverbanks and lakeshores and have been introduced to many countries to set up mink breeding farms for producing fur. From these farms Mustela vison have consequently escaped and become naturalised in many locations. In some instances there have been intentional releases by fur farmers hoping to produce better quality "free-range" fur (mainly in Eastern Europe) and intentional release by animal activists. In countries where fur farms still operate, mink still frequently escape into the surrounding environment. In introduced locations the mink has proved to be an extremely competitive predator which has had a huge impact on prey populations.
Common Names: American mink, mink
91. Nicotiana glauca (shrub) English

94. Ophiostoma ulmi sensu lato (fungus) English     
Dutch elm disease (DED) is a wilt disease caused by a pathogenic fungus disseminated by specialised bark beetles. There have been two destructive pandemics of the disease in Europe and North America during the last century, caused by the successive introduction of two fungal pathogens: Ophiostoma ulmi and Ophiostoma novo-ulmi, the latter much more aggressive. The vector is represented by bark beetles, various different species of scolyts living on elm trees. These beetles breed under the bark of dying elm trees. The young adults fly from the DED infected pupal chambers to feed on healthy elm trees. As a consequence, spores of the fungus carried on the bodies of these beetles are deposited in healthy plant tissue. Ophiostoma ulmi sensu lato can also spread via root grafts.
Common Names: dutch elm disease, Schlauchpilz
Synonyms: Ceratocystis ulmi
95. Orconectes rusticus (crustacean) English   
Orconectes rusticus, the rusty crayfish, is an aquatic invasive spread by anglers who use them as bait. It is native to the portions of Ohio, Indiana, Illinois, and Kentucky and has spread to surrounding areas as well as northeastern United States. O. rusticus is an aggressive and rapidly spreading crayfish that displaces cogeners, reduces macrophyte and invertebrate abundance, preys on native snails, and reduces sport fish populations.
Common Names: rusty crayfish

97. Oxyura jamaicensis (bird) English   
Oxyura jamaicensis (ruddy duck) is native to North America. It was imported into wildfowl collections in the UK in the 1940s and subsequently escaped to form a feral population from which birds are now spreading as far as Spain, where they threaten the globally endangered white-headed duck (Oxyura leucocephala) with extinction through introgressive hybridisation and competition. A regional trial of control measures, in which over 2,000 birds have been controlled, is ongoing in the UK. Control programmes are also in place in France, Spain and Portugal and are urgently needed in The Netherlands and Belgium. Oxyura jamaicensis are relatively easy to shoot as they tend not to leave water-bodies during control activities.

98. Pacifastacus leniusculus (crustacean)
Pacifastacus leniusculus is a large, hardy cool temperate freshwater crayfish that is found in rivers and lakes. It is endemic to northwestern USA and southwestern Canada, from where it was introduced into more southerly states, as well as into Europe and Japan. Pacifastacus leniusculus is an aggressive competitor and has been responsible for displacing indigenous crayfish species wherever it has been introduced. In addition, it acts as a vector for the crayfish plague fungus, Aphanomyces astaci, to which all non-North American crayfish are susceptible, but to which it is relatively immune. Pacifastacus leniusculus is a large, relatively fast-growing species with high fecundity. Consequently, it has proved a good aquacultural species and supports capture fisheries in the western USA and Europe, particularly in Finland and Sweden.
Common Names: Californian crayfish, Pacific crayfish, signal crayfish

It advances quickly and can kill large trees within several years. The disease has devastated the ornamental planting and timber industry of Port Orford-cedar throughout the Pacific Northwest causing losses of millions of dollars. In natural ecosystems P. lateralis reduces populations of this important tree in riparian areas, which may have flow on effects to terrestrial and aquatic life. Control efforts are focused on reducing spread of this pathogen via roads, and the development of resistant populations.
Common Names: cedar root disease, Port Orford-cedar root disease, Port-Orford cedar root rot, root rot of Chamaecyparis
103. Phytophthora ramorum (oomycete)
Until 2000, Phytophthora ramorum, the causal agent of Sudden Oak Death, was undiscovered and unnamed. This water mould or oomycete is the cause of much concern in North America and Europe due to three factors: (i) the high level of local destruction it causes in California, (ii) the lack of knowledge of its epidemiology (due to its recent discovery), and (iii) its high prevalence in nurseries (which increases the potential of spread to a new location and/or country). The oomycete has an extensive host range, covering many plant genera and several families and including treees and shrubs and woody and herbaceous perennials. Phytophthora ramorum causes canker development, shoot drooping and leaf blight. Spores spread to new locations mainly by the nursery trade and are spread locally by vectors: soil, water and articles associated with humans.
Common Names: maladie de l’encre des chênes rouges, mort subite du chêne, ramorum blight, ramorum dieback, ramorum leaf blight, SOD, sudden oak death
104. Pittosporum undulatum (tree, shrub) English

108. Procambarus clarkii (crustacean)
Procambarus clarkii is a highly adaptable, tolerant, and fecund freshwater crayfish that may inhabit a wide range of aquatic environments. It is native to parts of Mexico and the United States and has established throughout the world as a result of commercial introductions for harvest as a food source. Invasive populations have been reported from Europe, Asia, Africa, North America, and South America. Impacts include aggressive competition with native crayfish, introduction of the crayfish plague, reduction of macrophyte assemblages, alteration of water quality, predation on and competition with a variety of aquatic species, and negative impacts on agricultural and fishing industries. Management strategies for P. clarkii include trapping and removing populations, creating barriers to prevent its spread, prohibiting the transport of live crayfish, and improving public education about it risks to the environment. Encouraging farming of native species as well as research on economically productive harvesting of native crayfish has the potential to reduce further introductions.
Common Names: Louisiana crayfish, red swamp crayfish
109. Psidium guajava (tree, shrub) English  français     
Psidium guajava is a tropical tree or shrub. It is native to central America from Mexico to northern South America. It has been introduced to most tropical and sub-tropical locations around the world for its edible fruit. In some countries the harvesting, processing and export of the fruit forms the basis of a sizeable industry. Due in part to its ability to grow on a variety of soils and across a range of climates, P. guajava has become invasive . Pastures and fields are overrun and native plants are outcompeted by this species, which has the ability to form dense thickets. This has led to its designation in many areas as a noxious weed to be controlled or eradicated. It is ranked by some authorities amongst the highest invasive categories.

115. Rhododendron ponticum (shrub)
         Interim profile, incomplete information
Rhododendron ponticum often simply called rhododendron, is an evergreen shrub that has been widely cultivated as an attractive ornamental species. In ideal conditions R. ponticum can form dense stands which can inhibit the regeneration of native species and alter plant and animal communities. Control of R. ponticum is best achieved using a combination of physical and chemical methods, however this is usually an expensive and labour intensive process due to the high numbers of wind dispersed seed produced and the ability to resprout vigorously from its stumps and roots.
Common Names: common rhododendron, Pontian rhododendron, rhododendron
Synonyms: Rhododendron lancifolium Moench, Rhododendron speciosum (Willd.) Sweet.
116. Robinia pseudoacacia (tree) English  français

119. Salvinia molesta (aquatic plant, herb) English  français     
Salvinia molesta is a floating aquatic fern that thrives in slow-moving, nutrient-rich, warm, freshwater. A rapidly growing competitive plant, it is dispersed long distances within a waterbody (via water currents) and between waterbodies (via animals and contaminated equipment, boats or vehicles). It is cultivated by aquarium and pond owners and it is sometimes released by flooding, or by intentional dumping. S. molesta can form dense vegetation mats that reduce water-flow and lower the light and oxygen levels in the water. This stagnant dark environment negatively affects the biodiversity and abundance of freshwater species, including fish and submerged aquatic plants.Salvinia invasions can alter wetland ecosystems and cause wetland habitat loss. Salvinia invasions also pose a severe threat to socio-economic activities dependent on open, flowing and/or high quality waterbodies, including hydro-electricity generation, fishing and boat transport.
S. molesta in 2013 was elected as the one of the '100 of the World's Worst Invasive Alien Species' to replace the Rinderpest virus which was declared eradicated in the wild in 2010
Common Names: African payal , African pyle, aquarium watermoss, fougère d’eau, giant salvinia , giant salvinia , kariba weed , koi kandy, salvinia, water fern , water spangles

Common Names: single horn bryozoan
Synonyms: Lepralia unicornis (Johnston, 1874), Schizoporella unicornis (Lagaaiji, 1952)
122. Scyphophorus acupunctatus (insect)
         Interim profile, incomplete information  See eradication or other absence information
Scyphophorus acupunctatus is becoming a major pest of native Agavaceae and Dracaenaceae species worldwide. Native to Mexico, it has decimated populations of Agave crops there, in particular species used in the tequila and henequen industries. The importation of ornamental Agave plants worldwide has facilitated S. acupunctatus to establish in many parts of the world, particularly in Central America and the Carribean, in Africa, Asia and South America. On its host species, it causes rot and sometimes mortality due to its larvae boring holes which then facilitates micro-organims entering the host. Due to the species being found generally inside the host species, typical insecticides have proven ineffective. However research on the species' pheromones has shown that these could be a potential management tool, attracting individual adults away from hosts to collection sites.
Common Names: Acapiche del nardo, Agave billbug, Agave snout weevil, Agave snout-nosed beetle, Agave snout-nosed weevil, Agave weevil, black weevil, sisal borer, sisal weevil

125. Sesbania punicea (shrub)
Commonly known as Brazilian rattlebox, Sesbania punicea is a deciduous, leguminous shrub that has been widely distributed from its native South American range as an attractive ornamental species. Escapes from cultivation have led to naturalisation in some areas where S. punicea rapidly forms dense impenetrable stands in riparian areas, preventing river access, excluding native species and altering habitats. Hydrology of the rivers in these riparian areas can be affected especially during flood events, raising water levels and increasing the rate of erosion. Biological control of S. punicea has been achieved in South Africa using three different weevil species and trials from the United States and South Africa have shown its vulnerability to a range of herbicides.
Common Names: Brazilian glory-pea, Brazilian rattlebox, Chinese wisteria , coffee weed, rattelbox, rattlebox, rattlepod, red sesbania, rooi sesbania, ruttle bush, scarlett wisteria, sesbania

129. Sus scrofa (mammal) English  français     
  See eradication or other absence information
Sus scrofa (feral pigs) are escaped or released domestic animals which have been introduced to many parts of the world. They damage crops, stock and property, and transmit many diseases such as Leptospirosis and Foot and Mouth disease. Rooting pigs dig up large areas of native vegetation and spread weeds, disrupting ecological processes such as succession and species composition. Sus scrofa are omnivorous and their diet can include juvenile land tortoises, sea turtles, sea birds, endemic reptiles and macro-invertebrates. Management of Sus scrofa is complicated by the fact that complete eradication is often not acceptable to communities that value feral pigs for hunting and food.

133. Trachycarpus fortunei (palm)
Trachycarpus fortunei, commonly known as the Chinese windmill palm, is an evergreen palm that is primarily cultivated for ornamental purposes. Recognisable by its large, fan-shaped leaves, it can grow in varied climates - from warm-temperate to sub-tropical. It is one of the cold-hardiest palm species. This temperature sensitivity has allowed T. fortunei to be used as a bioindicator for tracking climate change, as recent range increases correlate with climactic warming. Seeds are spread by birds, and plants are frequently documented as escaped from cultivation. However, seedlings are climatically more sensitive than adult palms and thus seedlings are not always successful in establishing, particularly in areas at the edge of the plant’s distribution. Invaded environments include fragmented and natural forests, disturbed areas, riparian zones, shrub and scrublands, urban areas and wetlands.

Biostatus not specified

1. Cryptococcus fagisuga
The beech scale insect (Cryptococcus fagisuga), along with Neonectria ascomycete fungi form the disease-complex responsible for beech bark disease (BBD) of American and European beech. Beech scale infests mainly larger sized beech trees, feeding on host tissues and causing small fissures on the bark. This initial damage to the tree allows Neonectria to enter the tree, which kills host tissue and eventually girdles the tree causing it to die. In North America the main fungi involved are N. faginata and N. ditissima, whereas in Europe N. ditissima and N. coccinea are responsible for the disease. BBD can dramatically alter forest stand composition and structure, through loss of large trees and proliferation of smaller trees that originate from root sprouting. Reduction of beech nut production and loss of large trees in infected stands may affect mammals and birds that use beech nuts as important food source and old trees as habitat. Around 1% of American beech is estimated to be resistant to BBD. Research is currently focused on modes of inheritance and propagation methods.

3. Newcastle disease virus (NDV) (micro-organism)
Virulent Newcastle disease (vND) or Newcastle Disease (NDV) is a contagious and fatal strain of Newcastle disease which is carried by numerous wild and domestic bird species. Newcastle disease virus is a paramyxovirus that is contagious and fatal to avian fauna. It is probably one of the most infectious diseases of poultry in the world and death rates of 100 percent can occur in unvaccinated flocks. Many birds die without showing any clinical signs and the virus may even cause mortality in vaccinated flocks. Newcastle virus is easily spread by bird secretions and excretions and once contracted there is no treatment. Current methods of control are aimed at preventing its spread and include restricting the import of live birds from countries where the disease is present and culling infected birds.
Common Names: atypical geflugelpest, avian distemper, avian paramyxovirus type 1 (APMV-1), avian pest, avian pneumoencephalitis, exotic newcastle disease, Korean fowl plague, pseudo-fowl pest, pseudo-poultry plague, pseudovogel-pest, Ranikhet disease, Tetelo disease
Synonyms: Ranikhet Disease, Velogenic Newcastle Disease
4. Pinus spp. (tree) English     
Pinus spp.(pines) are considered to be the most ecologically and economically significant tree genus in the world, distinguished from other conifers in their role as an aggressive post-disturbance coloniser. The natural range for pines is in the northern hemisphere, but they have been cultivated in many parts of the world, forming the foundation of exotic forestry enterprises in many southern hemisphere countries. In many of these areas, pines have invaded the adjacent natural vegetation, and they are now amongst the most widespread and damaging invasive alien trees in the world.
Common Names: Austrian pine (P. nigra ssp. nigra), big cone pine (P. coulteri), bishop pine (P. muricata), contorta (P. contorta), lodgepole pine (P. contorta), maritime pine (P. pinaster), Monterrey pine (P. radiata), Ponderosa pine (P. ponderosa), radiata pine (P. radiata), remarkable pine (P. radiata, Scots pine (P. sylvestris), wilding pines
5. Plasmodium relictum (micro-organism) English     
The protozoa, Plasmodium relictum, is one of the causative parasites of avian malaria and may be lethal to species which have not evolved resistance to the disease (e.g. penguins). It may be devastating to highly susceptible avifauna that has evolved in the absence of this organism, such as native Hawaiian birds. The parasite cannot be transmitted directly from one bird to another, but requires a mosquito to move from one bird to another. In Hawaii, the mosquito that transmits Plasmodium relictum is the common house mosquito, Culex quinquefasciatus. Passerine birds are the most common victims of avian malaria.
Common Names: avian malaria, paludisme des oiseaux, Vogelmalaria
Synonyms: Haemamoeba relicta Grassi and Feletti 1891, Plasmodium capistrani Russell 1932, Plasmodium inconsta Hartman 1927
6. Psidium guajava (tree, shrub) English  français     
Psidium guajava is a tropical tree or shrub. It is native to central America from Mexico to northern South America. It has been introduced to most tropical and sub-tropical locations around the world for its edible fruit. In some countries the harvesting, processing and export of the fruit forms the basis of a sizeable industry. Due in part to its ability to grow on a variety of soils and across a range of climates, P. guajava has become invasive . Pastures and fields are overrun and native plants are outcompeted by this species, which has the ability to form dense thickets. This has led to its designation in many areas as a noxious weed to be controlled or eradicated. It is ranked by some authorities amongst the highest invasive categories.

7. West Nile virus (micro-organism) English   
West Nile virus (WNV) is a mosquito-borne flavivirus native to Africa, Europe, and Western Asia. WNV is mostly transmitted by Culex mosquitoes in a cycle involving birds as amplifying hosts. However infected mosquitoes can also transmit the virus to other animals and humans. Most animals are “dead-end” hosts and do not contribute to virus spread or evolution in nature, because infection in non-avian species results in low virus levels that is insufficient for infection of mosquitoes.
Since its introduction into the United States in the New York City area in 1999 WNV has continued to expand its range across the United States and into Canada, Mexico and Central and South America. WNV causes severe disease humans, horses and other vertebrates. Most people infected with West Nile virus have only mild illness. However the virus can also cause severe neuroinvasive diseases, often leading to death. No specific medication exists to treat West Nile virus infection, and there is currently no vaccine available for humans. Control measures focus on reducing mosquito breeding habitat: standing water in urban areas, agricultural areas, and wetlands.
Common Names: West Nile virus

14. Butomus umbellatus (aquatic plant) English     
Butomus umbellatus commonly known as flowering rush, is a moderately tall, rush like perennial found on shores of lakes, ponds and riverbanks. It can tolerate water as deep or deeper than 2 metres, extending to the deepest range of emergent marsh species. Flowering rush can displace native riparian vegetation, and can be an obstacle to boat traffic. Once established, populations' increase and can persist indefinitely. Control of this species is very difficult, especially with herbicides because they easily wash away from the narrow leaves of this plant. Extensive physical methods of control must be employed to manage this invasive exotic. It can be spread over long distances by garden planting, and once established in a watershed it spreads locally by rhizomes and root pieces that break off. Muskrats use parts of the plant and contribute to its local spread. Boaters can also transport flowering rush on their equipment.
Common Names: butome à ombelle, flowering rush, flûteau, grassy rush, jonc fleuri, water gladiolus

23. Clematis vitalba (vine, climber) English     
Clematis vitalba is a perennial vine with climbing, woody stems that can grow 20 to 30 metres long. In the native ranges C. vitalba is associated with chalk and limestone areas, but outside of its native range, this species is found in forestlands and in the margins and openings of forested lands. It is also found in riparian areas established with willows, in waste areas, and in coastal and lowland areas. This species physically smothers and collapses indigenous forest and causes a loss of indigenous plant species. When this loss occurs there is an influx of exotic plants into gaps or grazing damage by livestock. Control using a combination of mechanical and chemical methods can be effective but is very expensive. Much research is being conducted in the hopes of discovering biological means to control this species.
Common Names: evergreen clematis, Gewoehnliche Waldrebe, old man's beard, powojnik pnacy, traveler's-joy

30. Cynoglossum officinale (herb) English     
Cynoglossum officinale otherwise known as hound's tongue in common vernacular is a biennial herbaceous plant that invades disturbed areas and waste places. It occurs widespread throughout North America, in the U.S. and Canada. The leaves of the plant, in particular the rosette leaves, are high in toxic alkaloids that can poison livestock. Hound's tongue also has a thick, deep taproot that makes it successful at competing with native vegetation for soil resources. The seeds of hound's tongue are burred so they easily attach to the fur of animals or on the clothing and shoes of humans allowing them to spread to new uninfested areas.

31. Cytisus scoparius (shrub) English     
The densely growing Cytisus scoparius is a shrub indigenous to Europe and northern Asia that favours temperate climates and is found in abundance on sandy pastures and heaths. It is sparingly naturalized in sandy soil in North America. It grows best in dry, sandy soils in full sunlight and can also do well on soils high in boron. Where introduced, it colonizes pastures and cultivated fields, dry scrubland and "wasteland", and native grasslands. Most rapid spread of the plant has occurred along waterways where the seed is distributed by water. It is also spread rapidly along roads, where the seed is distributed by passing vehicles. Wind, birds, and other animals may also transport seeds. Seed re-introduction may occur from the sheep droppings during grazing.

Synonyms: Rhamnus frangula L., Rhamnus frangula subsp. columnaris hort. , Rhamnus frangula var. angustifolia Loud.
40. Genista monspessulana (shrub)
         Interim profile, incomplete information
The evergreen shrub Genista monspessulana, commonly known as French broom or Cape broom is capable of forming dense thickets in native vegetation, on grazing land, roadsides etc. These dense infestations can exclude native species. They are toxic to cattle if grazed excessively. French broom also increase fire fuel-loads in agricultural areas and in native vegetation. Fire stimulates seed germination by breaking the dormancy of soil-stored seed resulting in dense recruitment of seedlings. A small percentage of seeds are also capable of germinating on exposure to suitable temperature and soil moisture conditions. This variation in seed dormancy and germination increases the difficulty of control.
Common Names: Canary broom, Cape broom, French broom, Montpellier broom, Montpellierbrem, soft broom

Nymphoides peltata is usually introduced as an aquatic ornament though it is not the case in its native area. However, the sale and distribution of Nymphoides peltata is slowing becoming more controlled. It can become extremely invasive in shallow, slow-moving swamps, rivers, lakes and ponds. Currently there is little information available on the control of Nymphoides peltata but hand removal for small infestations and herbicides for larger infestations seem to be the most effective.
Common Names: asaza, entire marshwort, floating heart, fringed water lily, xing cai, yellow floatingheart
Synonyms: Limnanthemum peltatum Gmel., Nymphoides nymphaeoides (L.) Britt.
64. Onopordum acanthium (herb) English     
Onopordum acanthium is a herb of the sunflower family (Asteraceae) that is native to Europe and Asia. It has been introduced to temperate climates elsewhere, including much of North America and Australia. In North America, Onopordum acanthium is a weed problem on western rangeland and produces significant economic losses for ranchers. Seeds are dispersed locally by wind, humans, water, livestock, and wildlife are involved in long distance dispersal.
Common Names: cotton thistle, heraldic thistle, Scotch cotton thistle, Scotch thistle, woolly thistle
65. Orthotomicus erosus (insect)
Orthotomicus erosus is an engraver beetle of the family Scolytidae. It is being introduced around the world, often due to the wood packaging material used in the shipment of textiles and other products. Orthotomicus erosus is a carrier for pathogenic fungi and is known to carry Sphaeropsis sapinea, which causes extensive mortality of many Pinus spp.
Common Names: European bark beetle, Mediterranean pine engraver beetle
66. Ostrea edulis (mollusc) English   
Ostrea edulis (the European flat oyster) is native to Europe and the Mediterranean. It has been introduced to the northwestern Atlantic Ocean for aquaculture. Usually found in muddy areas, O. edulis has long been harvested for food. Over-harvesting in its native range, however, has caused it to be reintroduced to Europe. While in Atlantic waters, O. edulis became infected with the disease bonamiasis (Bonamia ostrae). This disease has caused widespread mortality in the vast majority of O. edulis.
Common Names: common oyster, edible oyster, eetbare oester, Essbare euster, European flat oyster, European oyster, huître comestible, huître plate Européenne, istiride, native oyster, oester, ostra Europa, platte oester, stridia, stridie, ustritsa
Synonyms: Ostrea adriatica Lam-Middendorff 1848, Ostrea taurica Krynicki 1837
67. Panicum repens (grass) English     
Panicum repens is a perennial grass that frequently forms dense colonies and has long, creeping rhizomes. It grows in moist, often sandy soils and its rhizomes often extend several feet out into the water. Panicum repens frequently forms dense floating mats that impede water flow in ditches and canals and restrict recreational use of shoreline areas of lakes and ponds. Management of Panicum repens involves the repeated application of herbicides. There is very little physical management that can be used to control Panicum repens, as disturbance encourages its growth.

69. Phalaris arundinacea (grass) English     
Phalaris arundinacea is a cool-season perennial grass that grows successfully in northern latitudes and can be invasive in wet habitats. Since it is tolerant of freezing temperatures and begins to grow very early in the spring, it can outcompete many other species. Any moist, fertile habitat provides good conditions for P. arundinacea. It is considered a serious threat in wet meadows, wetlands, marshes, fens, old fields, floodplains, wet prairies, roadsides and ditchbanks. The invasion is promoted by disturbances, such as ditching of wetlands, stream channels, deforestation of swamp forests, sedimentation, overgrazing and intentional planting. P. arundinacea tolerates frequent and prolonged flooding as well as submergence. It is moderately tolerant of drought and saline or alkaline soils. P. arundinacea spreads within sites by creeping rhizomes and forms dense and impenetrable mats of vegetation. New sites are colonised by seeds. P. arundinacea tolerates a small amount of shade, such as forest edges but not closed forest interiors.

75. Populus alba (tree) English     
Populus alba is a member of the willow family (Salicaceae) that is native to Eurasia. It is a dioecious species and female mature trees can produce large seed crops. Populus alba spreads to new locations when mature trees release thousands of wind-dispersed seeds that may be carried long distances. It is an especially strong competitor as it can grow in a variety of soils and resprout easily in response to damage. Local spread of male and female trees occurs vegetatively via root suckers.
Common Names: alamo blanco, gattice, gin-doro, hakuyo, peuplier blanc, pioppo bianco, silber-pappel, silver-leaf poplar, urajiro-hako-yanagi, white poplar, xin bai yang
Synonyms: Populus alba L. var. bolleana (Lauche), Populus alba L. var. pyramidalis (Bunge)
76. Porphyrio porphyrio (bird)
The ecological similarity of the purple swamphen (Porphyrio porphyrio) to the Florida native common moorhen (Gallinula chloropus) and purple gallinule (Porphyrula martinica) have prompted efforts to eliminate this member of the rail family from Florida. It is not clear what negative consequences could result from these non-native birds but in other parts of the world they are noted for their aggressive behaviour and their habit of eating other bird's eggs.

77. Potamogeton perfoliatus (aquatic plant) English     
Potamogeton perfoliatus is a submerged aquatic plant that occurs in still and flowing freshwaters in temperate climates. It is known as clasped pondweed as the leaf bases perfoliate (are wrapped around the stem). This is one of the commonest pondweeds. All the leaves are under water; there are no floating leaves as in some other common Potamogeton species. It is common in lakes, ditches and slow rivers and streams, and is tolerant of quite a wide range of nutrient status.
Common Names: claspingleaf pondweed , perfoliate pondweed, redhead grass
Synonyms: Potamogeton amplexicaulis Kar., Potamogeton bupleuroides Fern., Potamogeton perfoliatus ssp. bupleuroides (Fern.) Hultén, Potamogeton perfoliatus var. bupleuroides (Fern.) Farw.
78. Ranunculus ficaria (herb) English     
Ranunculus ficaria is a perennial plant and spring ephemeral (lasting for a very short time) that spends much of the year underground as thickened tubers. In the North American region, native ephemeral wildflowers grow and flower early in the spring before leaf-out of the forest canopy. Ranunculus ficaria uses this same strategy, but starts growing earlier in the season and is far more aggressive in its use of space. It out-competes native plants through its extremely early seasonal growth and forms extensive carpets in natural areas, crowding out native plants. Management primarily consists of delicate chemical treatments that must occur before native species emerge. Care must also be taken not to cause harm to flora that is emergent during chemical treatments.
Common Names: ficaire, fig buttercup , lesser celandine, pilewort , renoncule ficaire
79. Rhamnus alaternus (tree) English     
Rhamnus alaternus is an evergreen tree native to the Mediterranean. It was introduced to many areas of the Australasian-Pacific region as an ornamental plant in the 1900s where it became an invasive tree along coastlines and forests because of its ability to form dense stands that eventually exclude all other types of vegetation.
Common Names: alaterne, evergreen buckthorn, Italian buckthorn
80. Rhamnus cathartica (tree) English     
Rhamnus cathartica commonly known as common or European buckthorn is a deciduous small tree that prefers lightly shaded conditions. It is tolerant of many soil types and can be found in open oak woods, deadfall openings in woodlands and edges of woodlands. It may also be found in prairies and open fields. It tends to form dense, often even-aged thickets, crowding and shading out native shrubs and herbs. In fire-adapted ecosystems the lack of vegetation under buckthorn prohibits fires. R. cathartica is also an alternate host of the crown rust of oats. Fire is very effective in controlling R. cathartica and is a preferred method when the population is young. In wetlands water tables have been artificially lowered in order to attempt to control this species.
Common Names: buckthorn, Carolina buckthorn, cervispina, common buckthorn , épine noire, espinheiro-cerval, European buckthorn , European waythorn , Hart's thorn , Kreuzdorn, nerprun cathartique, nerprun purgatif, tamuje
81. Rubus discolor (vine, climber) English     
Rubus discolor is a perennial species of blackberry that forms large impenetrable thickets of prickly canes.

92. Salsola tragus (shrub) English     
Salsola tragus is an annual weed that begins life as a typical multiple branched bush but then takes on a spherical form. Once the spherical form is achieved the plant breaks at the soil line and becomes a tumbleweed which is blown by the wind, spreading thousands of seeds. It is abundant in semi-desert regions and is a typical plant of salty soils, where rainfall is not abundant. It infests range and semi-arid pasture lands as well as cropland, railroad, and highway rights of way, as well as vacant agricultural, residential and industrial areas. Salsola tragus is a road hazard, as tumbling plants can surprise drivers and cause traffic accidents. It is also responsible for allergic sensitisation in Europe and North America. It should be noted that nitrates and soluble oxalates accumulate in the plants photosynthetic parts at levels poisonous to sheep.

99. Streptopelia decaocto (bird) English  français 
The Eurasian collared-dove (Streptopelia decaocto) is an extremely successful invader capable of phenomenal range expansion despite geographic barriers. In Europe, it spread from Turkey and the Balkans colonizing almost every country in Western Europe in a matter of 30 years, becoming viable breeders within two years of invasion. Believed introduced to the West Indies by accidental release of a pet trader in 1974, Eurasian collared-doves have spread throughout the Caribbean. In the early 1980's they invaded Florida and quickly established localities throughout the southeastern United States. Researchers cite factors such as genetic mutation, keen adaptation to human-dominated environments, and high reproductive potential as possible explanations for their abundant range expansion. Negative impacts include competition with endemic birds and potential disease transmission.

101. Tomicus piniperda (insect)
The international movement of non-native forest insects is a threat to forest sustainability worldwide. Tomicus species (Coleoptera, Scolytidae) are important pests of pine forest in Eurasia, Europe and the Mediterranean, with the common pine shoot beetle (Tomicus piniperda) reported to be the second most destructive shoot-feeding species in Europe. Unlike deciduous trees, which can easily replace their foliage soon after defoliation, conifers are not able to replace their foliage as readily. As such, Tomicus piniperda can permanently destroy the shoots and severely hinder the development of new foliage.
Common Names: common pine shoot beetle, larger pine shoot beetle, pine shoot beetle , PSB
102. Trapa natans (aquatic plant) English     
Trapa natans, commomly known as water chestnut, is an annual plant introduced from Asia and has become abundant in the northeastern United States where it creates a nuisance in lakes, ponds, canals and other slow-moving water. Trapa natans grows best in shallow, nutrient-rich lakes and rivers and is generally found in waters with a pH range of 6.7 to 8.2 and alkalinity of 12 to 128 mg/L of calcium carbonate. Trapa natans out-competes native plants for sunlight and spreads either by the rosettes detaching from their stems and floating to another area, or more often by the nuts being swept by currents or waves to other parts of the lake or river.
Common Names: bull nut, European water chestnut, water chestnut, water nut

106. Typha latifolia (aquatic plant) English     
Typha latifolia (cattails) are among the most common of all aquatic plants. They are often a nuisance but also perform an important function in keeping a lake healthy by filtering the runoffs. Typha latifolia form dense monocultures when there is a wetland disturbance. They can reach up to 2 or 3 metres and grow prolifically from thick underground rhizomes, forming dense rhizome mats and litter which has an impact on species diversity by alteration of habitat. Dense Typha latifolia growth and litter may reduce the opportunity for other plants to establish or survive.

107. Ulex europaeus (tree, shrub) English  français     
Ulex europaeus is a spiny, perennial, evergreen shrub that grows in dense and impenetrable thickets which exclude grazing animals. It is common in disturbed areas, grasslands, shrublands, forest margins, coastal habitats and waste places. Ulex europaeus is a very successful and tenacious plant once it becomes established and is extremely competitive, displacing cultivated and native plants, and altering soil conditions by fixing nitrogen and acidifying the soil. It creates an extreme fire hazard due to abundant dead material and its oily, highly flammable foliage and seeds. Soil is often bare between individual plants, which increases erosion on steep slopes where Ulex europaeus has replaced grasses or forbs. Spiny and mostly unpalatable when mature, Ulex europaeus reduces pasture quality where it invades rangeland. Ulex europaeus understorey in cultivated forests interferes with operations; increasing pruning and thinning costs and can interfere with the growth of conifer seedlings.
Common Names: ajonc, ajonc d'Europe, bois jonc, chacay, furze, Gaspeldoorn, genêt, Ginestra spinosa, gorse, jonc marin, kolcolist zachodni, picapica, Stechginster, Tojo, vigneau, vIrish furze, whin, zépinard des hauts
108. Verbascum thapsus (herb) English     
Verbascum thapsus is an erect herb in the family Scrophulariaceae. It is found in neglected meadows and pasture lands, along fencerows and roadsides. It can produce 100,000-180,000 seeds per individual plant and seeds may remain viable for over 100 years. Verbascum thapsus threatens natural meadows and forest openings, where it adapts easily to a wide variety of site conditions and an established population can be extremely difficult to eradicate. Verbascum thapsus was once used as a herbal remedy for bronchitis, colds and congestion.

110. Vulpia bromoides (grass)
         Interim profile, incomplete information
Vulpia bromoides Is an annual weed of native grasslands and pastures in temperate climates of both the Northern and Southern hemispheres. Weedy annual grasses can reduce biodiversity on native grasslands, impede their restoration, and alter ecosystem processes. As a pasture weed, V. bromoides reduces productivity of grasslands; it has low palatability, and its seeds can damage hides and fleece of grazing animals. It readily invade wherever disturbance occurs. Integrated management which combines pasture rest, herbicide treatment and fertilizer application is shown to reduce seed production and improve control.
