Along with Mt Buller Victoria and Mt Bogong-Mt Hotham Victoria, Kosciuszko National Park is one of three areas where the critically endangered species Mountain Pygmy Possum is known to habit. The Mountain Pygmy Possum (Burramys parvus) is a small, mouse- sized marsupial that lives exclusively in Australia. With all of its habitats combined, it only adds up to 5 square kilometres, less than the size of Longreach. The decreasing size of the Mountain Pygmy Possum’s habitat is due to many reasons, including loss of habitat due to the increasing size of local ski resorts, predators such as feral cats and foxes, invasive plant species, habitat loss, climate change, inbreeding, depleted food sources, fires and human intervention into their habitats.
