On the North American plains, prairies, grasslands, and meadows at least 11% of grasses are non-native. [2] 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 ...

[9] Poa pratensis is the type species of the grass family Poaceae. There are two ill-defined subspecies: Poa pratensis subsp. pratensis – temperate regions; Poa pratensis subsp ...
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
Agrostis gigantea, known by its common names black bent [2] and redtop, is a perennial grass of the Agrostis genus. It is native to Europe, but in the cooler areas of North America was widely used as a pasture grass until the 1940s. Although it has largely been replaced by soybeans and more palatable grasses, it still gets some use in poor soils.
Andropogon virginicus can be problematic in pastures. Without proper herbicides, pasture management is nearly impossible with this type of weed. [8] This broomsedge bunchgrass is typically low in nutrients, so it is generally not browsed by deer or livestock, unless new growth is present. Farmers consider this grass to be a indicator of poor ...

The shrub-steppes of North America occur in the western United States and western Canada, in the rain shadow between the Cascades and Sierra Nevada on the west and the Rocky Mountains on the east.
