In total there are 13 tree kangaroos species in Australia, Papua New Guinea: all face the same threats of habitat loss. The stocky wallaroo, with his shaggy coat and short limbs, is well-adapted for leaping around rocks.
There are quite a lot more kangaroos than people in Australia. Figures from 2 million(way too low) up to 200 million (way too high) are thrown around, but the population is usually stated as being between 20 and 50 million. There is estimated to be enough farming land to support about 200 million kangaroos.
