Fancy ... in a way you are very fortunate not to have foxes down there in beautiful Tasmania.
But to think you have lost so many other birds and animals because of the eradication process with 1080 bait - is gruesome and just awful.
From your comment, perhaps there were never any foxes there in the first place ? .... I would think free ranging, wild 'families' of the Tassie 'devil' might have been a natural deterrent to any foxes. Figure they wouldn't like them too much.
Seems there has been some good progress made in curtailing the facial cancer that has infected so many of the Tassie devils. Saw where a new drug has had good success, obtained from the rainforests of Queensland ... called EBC-46. It has also been trialled for use on humans with cancer, and those trials are ongoing at this time.
There is still hope for our beloved devil, unfortunately the healthy ones that were released , were released too close to civilisation and almost half became victims to the road.
