Wildlife such as the South Andean Deer also registered high death rates.

The endangered South Andean Deer is found in the reserve.

The reserve protects the northernmost population of South Andean deer.

The south Andean deer is well-adapted to broken, difficult terrain with a stocky build and short legs.

While previously found over much of southwestern South America, the current status of the south Andean deer is critical.

The reserve contains the most southern occurrence of Austrocedrus chilensis and is home to some South Andean deer.

Chilean huemul or south Andean deer (Hippocamelus bisulcus)

Mammals in the reserve include South Andean deer, guanacos, pumas and canines of the genus Lycalopex.

The Huemul (Hippocamelus bisulcus), also known as the South Andean Deer, is found in Chile and Argentina.

Other species include guanaco, puma (cougar), lynx, pategonian fox, dwarf armadillo, ferret, skunk, tuco-tuco and south andean deer.

One of two mid-sized deer of the Hippocamelus genus, the south Andean deer ranges across the high mountainsides and cold valleys of the Andes.

Other notable fauna reported are several species of penguins, the South Andean deer or Huemul Hippocamelus bisulcus, and the southern river otter Lutra provocax.

The Huemul, also known as the South Andean deer, is, among other areas, found in Chilean Patagonia, where NIGSA is based.

The most common of these, the Lenga beech, was also a primary food item of the red deer, causing displacement to marginal areas and increased vulnerability for the smaller South Andean Deer.

Both decreased reproduction rates and increased morbidity may be affecting the population in Argentina; predation by the Cougar, the South Andean Deer's only natural predator, remains a principal cause of mortality in Argentina.

South Andean deer There's only around 2000 of the endangered South Andean deer or huemul alive, and together with the Andean condor, it features on Chile's National Coat of Arms.

In Argentina and Chile, the red deer has had a potentially adverse impact on native animal species, such as the South Andean deer or huemul; the International Union for Conservation of Nature and Natural Resources has labelled the animal as one of the world's 100 worst invaders.

Huemul (Hippocamelus bisulcus)

The Huemul (Hippocamelus bisulcus), also known as the South Andean Deer, is found in Chile and Argentina.

Other notable fauna reported are several species of penguins, the South Andean deer or Huemul Hippocamelus bisulcus, and the southern river otter Lutra provocax.

The coat of arms shows the two national animals: the condor (Vultur gryphus, a very large bird that lives in the mountains) and the huemul (Hippocamelus bisulcus, an endangered white tail deer).
