  2. Invasive grasses in North America - Wikipedia

    en.wikipedia.org/wiki/Invasive_grasses_in_North...

    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 ...

    en.wikipedia.org/wiki/Andropogon_gayanus

    Andropogon gayanus seeds. This tufting perennial bunchgrass can grow 4 m (13 ft) tall and 70 cm (2.3 ft) in diameter, and has hairy leaves.

  4. Invasive species in the United States - Wikipedia

    en.wikipedia.org/wiki/Invasive_species_in_the...

    The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...

  5. Andropogon virginicus - Wikipedia

    en.wikipedia.org/wiki/Andropogon_virginicus

    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 ...

    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 Although it has largely been replaced by soybeans and more palatable grasses, it still gets some use in poor soils.

  9. Lists of invasive species - Wikipedia

    en.wikipedia.org/wiki/Lists_of_invasive_species

    These are lists of invasive species by country or region. 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 ...
