About the rainforest
The Australian tropical rainforests contain over 2500 species of higher plants, representing more than 10% of the Australian flora. These rainforests stretch from the lowland and montane tropical rainforests of north east Queensland through to the drier and monsoonal rain forests of the Northern Territory and the Kimberley district of Western Australia.
The rainforests of the Wet Tropics area of north east Queensland are the most species rich. There is a decrease in species richness along the rainfall (strictly seasonality of rainfall) gradient to the monsoonal rain forests of Western Australia.
