Koalas need another 10,000 gum trees in south-east Queensland, vet says
Thousands more gum trees need to be planted to feed a growing number of sick koalas, the Currumbin Wildlife Hospital says.
About 15,000 eucalyptus trees have just been planted at Hinze Dam in the Gold Coast hinterland to feed koalas, but senior veterinarian Michael Pyne said at least 10,000 more were needed.
He said disease was contributing to a spike in hospital admissions and finding enough food was proving a challenge.
“You’ve got one nasty killer bacterial infection in chlamydia and then you’ve got a really nasty viral disease that suppresses the immune system so together of course it’s a nasty combination,” Dr Pyne said.
Warning: devil’s advocate mode.
Kangaroo Island needs 10,000 fewer koalas.
Perhaps that’s the solution for Currumbin, rather than more eucalypts. Fossil evidence has shown that there are more koalas in Australia now than ever before, and far more than before Europeans arrived.
On Kangaroo Island, more than 12,500 koalas have been sterilised. in 2010 the estimated population was 13,000 koalas, down from 27,000 in 2001. Nevertheless, koala densities still remain above sustainable densities
>>Some regions have seen their koala populations decline over a number of years, while others have relatively high populations. For example, koala populations on Kangaroo Island and in parts of Victoria are considered too large to be sustainable for their habitat and need to be managed through supervised translocation and sterilisation.
At the other end of the spectrum, koala populations in some parts of coastal Queensland and New South Wales face an increasing threat from urban expansion, disease, habitat loss, vehicle strike, and predation by dogs. Koala populations in these areas may also be more susceptible to the effects of drought and climate change.
Due to the wide variations in population size, health and status, the Threatened Species Scientific Committee recommended that a blanket or a one-size-fits-all approach to a koala species listing would be inappropriate and did not recommend a listing of the whole or national koala population.
The Committee recommended that koala populations in Queensland, New South Wales and the Australian Capital Territory were most at risk and required listing under national environment law to ensure the species sustainability. The Committee recommended that protecting koalas in these areas provided for the best conservation outcome for the koala.<
