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 Desert is the largest of the 40° parallel and is a large cold winter desert, where the temperature rarely exceeds 12 °C and averages just 3 °C. The region experiences about seven months of winter and five months of summer. Frost is not uncommon in the desert but, due to the very dry condition year round, snow is rare. The Andes, to the desert's west, are the primary reason for the Patagonian desert status as they inhibit the westerly flow of moisture from the southern Pacific from reaching inland. This creates a rain shadow that accounts for the formation of
