Koala Habitat Survey

2014 Feb Yellow Hill KoalaThe Crossing works with National Parks and Wildlife (Office of Environment and Heritage) on the biggest koala habitat survey in Australia. The project started in 2005.  The koalas between The Crossing and Tathra are the only known coastal NSW population south of Sydney.

The Wilderness Coast koalas have a unique genotype. Protecting and linking their habitat improves the chances of koalas connecting with remaining populations to the north and south.

Dr Alistair Mezler, Uni of Central Queensland, evidence to Senate Inquiry, May 2011:
…..'(these) koalas are probably the most critical population in Australia in the sense that they may represent one of only two reservoirs, very small ones, of what is the native genotype of all of the Victorian and South Australian animals left.’  

The Crossing’s habitat survey work has contributed to the Australian government listing koalas as vulnerable to extinction in NSW.  The work has also provided new insights on threatened species disturbance, climate change and ecology.

Young people have helped survey more than 250 square kilometres of forest to show where koala territories are, how few remain and what trees are important to koalas on the Wilderness Coast.

Survey and landcare support to surrounding farmers has also linked and enhanced habitat between the major coastal national parks on either side of The Crossing. The camp property and surrounds supports many endangered and vulnerable species listed on Schedules 1 and 2 of the Threatened Species Conservation Act 1995.

Koala Habitat Trees

koalaconsareamedThe most important trees for koalas on the Wilderness Coast are:

  1. Eucalyptus longifolia (woollybut)
  2. Eucalyptus globoidea (white stringybark)
  3. Eucalyptus cypellocarpa (monkey gum)

Also important are:

  • Eucalyptus tricarpa (ironbark)
  • Eucalyptus bosistoana (coast grey box)
  • Eucalyptus sieberi (silver topped ash)

The Crossing continues to involve young people in Habitat Survey as a core part of our programs.
