North America is considered a hotspot for many invasive species of grasses, which threatens all of the endangered native grass species and potentially threatens other grass species. Conservation tactics and management policies can help prevent invasive species from taking over and driving native North American plants to extinction.
The wildlife of Canada or biodiversity of Canada consist of over 80,000 classified species, [a] and an equal number thought yet to be recognized. [3] Known fauna and flora have been identified from five kingdoms: [ 4 ] protozoa represent approximately 1% of recorded species; chromist (approximately 4); fungis (approximately 16%); plants ...
The species is widely considered a weed even where it is native, for example being designated an "injurious weed" in the United Kingdom under the Weeds Act 1959. [37] It is also a serious invasive species in many additional regions where it has been introduced, usually accidentally as a contaminant in cereal crop seeds.
