Mountain Pygmy-possums can only be found in certain localities of Australia, namely: alpine/sub alpine parts above 1400 meters, in NSW and Victoria. The typical Mountain Pygmy-possum resides in crevices of rocks. They feed during the night. During trying times, they gather reserves by eating principally Bogong moths, but in more favorable times, they would eat plant seeds too.
There are very few marsupials which hibernate, and the Mountain Pygmy-possum is one of those. In hibernating, their metabolic rate is cut down by around 98%. They are known to hibernate for at least 3 weeks, in the coldest months.
The Mountain Pygmy-possum is not safe from extinction at present. Predators such as wild cats and foxes are of course, an ever-present danger to them. Then, there is the destruction of their habitat due to human factors/actions (like skiing, resort developing). Owing to the fact that these possums need a level (snow) of 1 meter (no less), any climate transformation has great impact on their survival.
Interesting fact: These possums were considered extinct until they were found at a ski chalet, sometime in the mid 1960s.
The Broom's pygmy-possum, burramys, mountain pygmy possum is listed as Endangered (EN), considered to be facing a very high risk of extinction in the wild, on the IUCN Red List of Threatened Species
