Koala Koalas are important to ecosystems in Australia in a few different ways. First, their droppings fertilise the forest floor, which promotes plant growth—and some small mammals and insects feast on them, too. Second, birds are known to use koala fur in their nests, as it is highly insulating. Third, koalas help preserve eucalyptus forests—if koalas disappeared, other animal populations that would then be able to access eucalyptus would surge, leading to the decimation of the trees.
