Why do we hear so much about the Australia rainforest? That is because the vast continent of Australia has a native total forest area which is perhaps the largest ecosystem in the world and the rainforests form a significant 3% or about 3.6 million hectares in a total of this nature’s bounty of biodiversity. Typically the rainforests have trees that thrive in abundant rainfall conditions growing to great heights and having large canopies under which many unique and endangered animals, insects, animals, and birds live and thrive in.
