BIOLOGICAL ISOLATION Due to the separation of Australia from the rest of the world, Australia has evolved differently from other countries which has resulted in inhabiting unique flora and fauna. Mount. Hotham in the Victorian Alps, is home to many unique animal species such as the Pigmy Possum and the Bogon Moth. These species are only found in this area and have adapted to the cool climates that occur at Mt. Hotham . The Pigmy possum was once thought to be extinct, until one was sited in 1966 at Mount Hotham. The Pigmy Possum is also the only mammal known to be restricted to the alpine areas due to biological reasons. Mount Hotham is also home to many flora species that have also adapted to the snowy, winter climates. They include the snow gum, mountain daisy, dwarf sedge and the fairy blue bell. CLIMATIC VARIATIONS The climate and temperatures in Mount Hotham can vary even though the area is prone to snowy conditions. During the spring and summer months of the year, it doesn’t snow, and instead the climate is dry and sunny. The average temperature during the day ranges from 10-21 degrees. Due to the high altitudes that Mt. Hotham is found in, temperatures don’t usually rise as high as those on the grassy flats of Victoria. And the high altitude also means this area is subject to snow fall. GEOLOGICAL STABILITY Mount Hotham was created due to a build up of deposits and sediments over 400 to 860 million years ago, while the whole of the eastern side of Australia was still under water. The Alps began to raise due to the tectonic process that occurred and which caused Australia to separate.
