Friends of the Koala operate a native plant nursery that specialises in koala food trees and many other native plants.

Koala food trees are provided free of charge to landholders in the Northern Rivers Region where koalas reside. Other plants are sold to provide funds to run the Koala Care Centre and to enable the group to undertake tree-planting activities.

The greatest threat to the long-term survival of the koala is habitat destruction. Many of the remaining belts of eucalypts along traditional koala routes have become severely fragmented. This increases koala susceptibility to disease, motor vehicle accidents and dog attacks. The koalas are under greater stress because food is harder to find and they spend more time on the ground as trees are further apart.

One of the aims of Friends of the Koala is to encourage landholders to undertake tree-planting activities to link up the existing patches of remnant koala habitat to create a more continuous corridor of food and shelter.
