East Australian Eucalyptus Forest Food Web
Terrestrial
Temperate Broadleaf & Mixed Forests
Eastern Australia — Queensland, New South Wales, Victoria
Description
Eastern Australian eucalyptus forests support iconic marsupials including koalas, wombats, and possums in a food web shaped by fire and drought. Eucalyptus leaves are toxic and low in nutrition, yet koalas and greater gliders have evolved to specialize on them. Kookaburras, goannas, and powerful owls are key predators.

Key Interactions
- Koalas specialize on toxic eucalyptus leaves using specialized gut microbiota
- Powerful owls are the largest Australian owl, preying on possums and gliders at night
- Bushfires create landscape-scale disturbance driving regeneration and species turnover
- Hollow-bearing old-growth eucalyptus trees provide nesting habitat for over 300 species
