    Organism type: grass
    Agrostis gigantea commonly known as redtop, is reported to be weedy or invasive in some states in the USA and provinces in Canada. Native to temperate and tropical Asia, parts of Europe and North Africa, it was introduced for use as turf or lawn grass, as a fodder and forage species or for erosion control and revegetation purposes. Its impacts include displacement of native species in habitats where it is not managed properly.
    Occurs in:
    range/grasslands, riparian zones, wetlands
    General impacts
    Agrostis gigantea impacts include displacement of native species in habitats where it is not managed properly. It also hybrises easliy and numerous non-typical plants can be found in most populations (Tilley et al 2010).
    Agrostis gigantea is used as a lawn/turf grass, for revegetation purposes and for erosion control. It is also used as a fodder and forage species (USDA-ARS, 2010)
    Geographical range
    Native range: Temperate and tropical Asia and Europe (USDA-ARS, 2010)
    Known introduced range: United States; Canada; Greenland (USDA-NRCS, 2010)
    Management information
    It is recommended not to use Agrostis gigantea for revegetation in habitats that being considered for revegatation by native species (Tilley et al 2010).
    Agrostis gigantea can be established by seed, sprigs, or sod (Tilley et al 2010).
