Patagonian grasslands and measurements for sustainable grazing, which can be used in branding clothes made of Patagonian wool. The theory, which is controversial, is that if sheep are moved frequently to emulate herds of wild animals avoiding predators they may actually help regenerate the grasslands. The decisions on where and how fast to move them depend on many ecological factors, and some academics are skeptical about whether real benefits can be achieved. 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
Patagonian crested duck female, and takes about 30 days, following which the eggs hatch synchronously. Once hatched both parents tend to the ducklings. They fledge at about 10–11 weeks old. The duck eats aquatic invertebrates such as insects and their larvae, crustaceans and molluscs. It also eats small amounts of aquatic plants such as the filamentous algae common in many ponds. The diet for the young is much the same as their parents. To get their food the ducks dive for algae and invertebrates at the bottom of waterbodies. Diet varies between fresh and salt water habitats, as well as seasonally. The Patagonian
