An acceptance of unreferenced anecdotes as proof (of eastern quolls being introduced to Bruny in the 1970s) alongside cynical dismissal of substantial material evidence that has passed several reviews (of foxes in Tasmania) sits very poorly with your call to just deal with facts Mr Clarke (letters, Mercury 15th).

I presume your anecdotal proof is nobody you know remembering eastern quolls to be on Bruny before 1970.

Maybe they were rare then and simply overlooked or just never officially recorded just like much wildlife there.

DNA comparisons suggests Bruny Island quolls have been separated from mainland Tasmanian populations for a lot longer than 40 years.

I remain to be convinced eastern quolls were introduced to Bruny in the 1970s. Radical boom-bust cycles are a natural feature of eastern quoll ecology and the current boom will bust.

There are no species on Bruny that do not cope with eastern quolls and or spotted-tailed quolls and devils elsewhere in Tasmania so who’s mounting the scare campaign Mr Clarke?

Eastern quolls are not top predators on Bruny. Masked owls prey on them as can cats and diurnal birds of prey are one reason they are nocturnal. Eastern quolls are extinct on mainland Australia mainly because of foxes and will be amongst the first to go if foxes get fully established here.

If you look beyond your backyard Mr Clarke you might find you actually have an asset.

Finally, I have never been head of wildlife management and my views sometimes conflict with those of the department.

I prefer to put devils on Bruny because its a restoration and not a range extension such as Maria Island, the department’s preference, and something being assessed for years before the Tasmanian Conservation Trust showed interest.
