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 into the logs, thus fossilizing the trees and creating one of the world's best preserved petrified forests in the desert's center. The Patagonian is mainly composed of gravel plains and plateaus with sandstone canyons and clay shapes dotting the landscape, sculpted by the desert wind. The region encompassing the desert, however, has many diverse features. Ephemeral rivers, lakes, and drainage deposits from the Andes' spring melt form annually, hosting a variety of waterfowl and aquatic grasses. A variety of glacial, fluvial, and volcanic deposits are also found in the region and have significantly affected the desert's climate over time, especially
