Lichens are widespread throughout Girraween National Park and can be found growing on the ground, on exposed rock or on the shaded trunks of trees.

Lichens are actually a fungus and an algae, living together in a symbiotic relationship. Both the fungus and algae can live as separate organisms, but working together they are more successful. The fungus surrounds the algal cells, protecting them and providing a larger "catchment" area for rain and dust - water and minerals that both organisms need to survive. In return, the algae can photosynthesis food for both itself and the fungus.

Lichens are fascinating and complicated organisms that play a crucial part in not only Girraween, but in the wider world as well.
