The Office and Environment and Heritage (OE&H) have released their Draft Far South Coast Regional Pest Management Strategy (2.11 Mb) for comment. Unfortunately the OE&H do not to take an environmental approach so any negative outcomes are generally ignored.
According to the OE&H ” . . . predation by wild dogs may have negative impacts on some threatened species. For example, dog predation can be a high source of mortality in koala populations and when combined with habitat fragmentation has the potential to cause local extinctions. While no major impacts on biodiversity have been recorded in the FSC Region, wild dogs have been identified as a potential threat to long-footed potoroo populations in the SEF NP.”
While the reference to ‘koala populations’ is consistent with their claims that koalas could be everywhere, the ‘potential threat to long-footed potoroo populations in the SEF NP’, is vague about the level of threat and the small areas this endangered species occupies. Both of these species survived the ‘threat’ posed by Dingos for thousands of years but, like many other native predators, particularly large forest owls, Dingos are now apparently extinct in local forests.
This extinction has been caused by the NSW Government’s broad area 1080 poisoning program, aimed at foxes and dogs, as well as the reduction and extinction of prey species. It is arguable that this program is based on a poor understanding of biodiversity and their commitment to 1080 poisoning assumes an understanding about biodiversity that the OE&H clearly doesn’t have.
For a different and interesting perspective on feral preditors this article is well worth reading.
