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 Desert Volcanic Field near the Strait of Magellan. The volcanic rocks are the result of back-arc volcanism distributed mainly in two episodes: one in the Eocene and Miocene and the other from Late Miocene to Pleistocene. Despite the harsh desert environment, a number of animals venture into and live in the Patagonian. Some only live on the more habitable and geographically-varied outskirts of the desert, where food is more abundant and the environment less hostile, but all are found within the region encompassing the Patagonian.
