Koalas In Care Inc. title

Koala Habitat

Koala habitat is the major determining factor in how koalas live their lives and indeed if they are to continue to survive in any particular area. Habitat serves many purposes such as providing shelter from the elements, food supply, a mating place, and a safe haven from predators.

Due to past clearing of vegetated areas for farming, logging and more recently, residential and industrial developments, koala habitat has significantly declined since European arrival in Australia. Much of the remaining koala habitat consists of a mosaic pattern of disturbed forest remnants and inadequate corridor linkages. Koalas are constantly struggling to survive in these depleted areas and are at increased risk of predator attack or being struck by motor vehicles while migrating through disturbed areas that roads transverse.

There are large variations in habitat across our area including:

  • Sandy loams of the coastal areas
  • Fertile alluvial floodplains and riparian areas
  • Rich volcanic of the upper escarpments and plateaux
  • Low fertile clay/shale ridges
  • Sub alpine areas of the Barrington Tops

Over 30 Eucalypt species are known to exist within our area, some quite common, whilst others are only in limited locations and some at their geographical limit. Koalas are also known to forage on non Eucalypt species such as Melaleucas and Angophoras.

When a project is being planned to increase koala food trees in an area, it is essential that only tubestock grown from locally collected seeds from known koala food trees are used. Unfortunately, some plant nurseries supply non-endemic species that our local koalas will not eat and these species have only weed value. It is also important to plant a variety of species to provide koalas with a varied diet.

Where trees should be planted?

  • Especially near existing koala habitat
  • Near water courses ie creeks, rivers, dams, etc
  • Between isolated remnants of habitat to provide connection
  • Adjacent to existing vegetation clumps
  • Close to fence lines
  • In quiet parks and reserves

 

Where not to plant trees!

  • Beside busy main roads
  • Close to your house
  • Fenced in with a swimming pool or dog yard
  • Close to or under power lines and pipes

 

Seed Bank

We have been collecting seed in the local area for many years and now have quite a large stock of various seeds. Contact us for more information and prices.

 

Tubestock

We have recently started to propagate tubestock for planting back into the local area. We are in the early stages of this project so stock is limited at present. We will be expanding this over time. Contact us for more information and prices.
