Koala habitat and feed trees

Koalas feed primarily on the leaves of eucalyptus trees. One of the most important factors influencing the distribution and numbers of koalas in any area is the presence and density of their food tree species.

 

Koalas feed almost exclusively on a few preferred tree species which are of primary and secondary importance. If primary tree food species are not present or occur in low density, koalas must rely on secondary food tree species, but the number of animals per hectare is lower. The occurrence of both primary and secondary tree species varies widely on a regional, local and even a seasonal basis, meaning that koalas are unevenly distributed across their range.

Although primary and secondary food trees provide most of a koala's diet, other tree species, including non-eucalypts, also provide seasonal or supplementary food.

Koalas also require a range of other trees across their habitat for resting and shelter, particularly in extreme weather conditions. Examples of shelter trees include turpentine, cypress pine and brush box.

Koala (Phascolarctos cinereus)

Koalas feed almost exclusively on a few preferred tree species.

Koala management areas

The NSW koala recovery plan (2008) identified 7 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 provided a list 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 are a number of local variations
  • koala populations can be monitored to assess and manage short-term management issues critical for conserving koalas throughout New South Wales.
