Invasive grasses in North America - Wikipedia
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.
