Patagonian grasslands Patagonian grasslands The Patagonian grasslands (NT0804) is an ecoregion in the south of Chile, Argentina and the Falkland Islands. The grasslands are home to diverse fauna, including several rare or endemic species of birds. There are few protected areas. The grasslands are threatened by overgrazing by sheep, which supply high-quality merino wool. Efforts are being made to develop sustainable grazing practices to avoid desertification. The Patagonian grasslands extend across eastern Tierra del Fuego in Chile and Argentina from near the southern cone, and cover part of Santa Cruz Province just north of the Strait of Magellan up to the Gallegos
Patagonian opossum of La Pampa and Choele Choel (northern Rio Negro Province). It is suggested that the Patagonian opossum may have emerged from the same ancestral group as "Marmosa". They resemble each other closely. In the winter both types have similarly thickening at the base of the tails, where fat accumulates. Yet they do not share all aspects of their lifestyle; Patagonian opossums have a specialized way to gather and consume food, which is made possible by the shortening of their skull and jaws. The shortening occurs in the premolar region; this gives the Patagonian opossum increased biting power. The general appearance
