Koala habitat and feed trees

Koalas are ecological specialists which feed primarily on eucalyptus trees. Arguably, the most important factor influencing the number and distribution of koalas in an area is the species of trees in that area.

Koalas feed almost exclusively on a few preferred primary and secondary food tree species. If primary tree food species are not present or occur in low density, koalas rely on secondary food tree species, but the number of animals per hectare is lower. Both primary and secondary tree species vary widely on a regional, local and possibly seasonal basis.

Although primary and secondary food trees provide most of a koala’s diet, leaves from other species, including non-eucalypts, may provide seasonal or supplementary food.

The quality of habitat is also influenced by the presence of shelter trees, particularly in harsh climates. Examples of shelter trees include cypress pine and brush box.

Koala management areas

The NSW recovery plan for the koala identifies seven koala management areas (KMAs). These areas enable the status and recovery of koalas to be monitored regionally.

The KMAs are based on:

  • landscape characteristics, particularly the geographic distribution of primary or secondary food tree species
  • administrative boundaries for ease of natural resource management.

The recovery plan provides lists of koala food trees categorised as primary, secondary and supplementary for each KMA.

Within each KMA:

  • habitat characteristics and threats are relatively consistent, although there is some local variation
  • decision-makers can monitor koala population structure and deal with short-term management issues critical for conserving koalas throughout NSW.

The main koala food trees in the seven management areas are listed below:

  1. North Coast
  2. Central Coast
  3. South Coast
  4. Northern Tablelands
  5. Central and Southern Tablelands
  6. Western Slopes and Plains
  7. Far West and South West.
