<P> Tussock grasses or bunch grasses are found as native plants in natural ecosystems, as forage in pastures, and as ornamental grasses in gardens . Tussock and bunch grasses, in the Poaceae family, are grasses that usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies . As perennial plants usually, they live more than one season . </P> <P> Many species have long roots that may reach 2 meters (6.6 ft) or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption . Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts . The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza . The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists . </P>
