    Management Notes for this Location:
    The ISSC (Invasive Species Steering Committee) of the Garry Oak Ecosystems Recovery Team (GOERT) (a partnership of a number of governmental and non-governmental agencies) which focuses on research and management of invasive species in Garry oak and associated ecosystems has developed a Decision Support Tool for Invasive Species management and Field Manual for invasive species. Please follow this link for the field manual for Passer domesticus.
    Location Notes:
    Garry oak (Quercus garryana) is a species of restricted range in Canada and North America, In Canada, Garry oak ecosystems (GOE) exist only in British Columbia ; almost exclusively within a narrow coastal strip of southeast Vancouver Island, in the nearby Gulf Islands, and in two small stands in the Fraser River Valley. In British Columbia, GOE are red-listed ecosytems that support high numbers of blue- and red-listed species of flora and fauna. The current global distribution of GOE spans an extensive north-south range, from southwestern British Columbia to southern California.

    Garry oak and associated ecosystems combined are home to more plant species than any other terrestrial ecosystem in coastal British Columbia. Many of these species occur nowhere else in Canada. These habitats also support 104 species of birds, 7 amphibians, 7 reptiles and 33 mammal species. Eight hundred insect and mite species are directly associated with Garry oak trees. Invasive species in GOE include plants and animals. At least 173 invasive species have been identified including 4 trees, 15 shrubs, 147 herbs, 1 reptile, 6 birds and 7 mammals.
