Detail in the Devil

Recently an number of Tasmanian Devils were moved from Tasmania to NSW. The Devil population has been considered extinct on the mainland of Australia (though with occasional sightings & road kill) so the move is to a semi wild managed area. The development of the deadly Devil Facial Tumour Disease (DFTD) has caused massive decrease in numbers of Devils in their native habitat, caused in part by low genetic diversity amongst the populations.
Now that a new population is being reinstated on the mainland in semi-wild conditions there may be a chance to isolate them against the disease.
Isolation of populations on islands is common, and is done with birds such as the flightless New Zealand Kiwi & Kakapo parrot. The problem with these sorts of approaches, (other than the human costs) is that the small populations are susceptible to disease and disaster, like the floods engulfing Queensland and parts of northern Victoria.
I have often wondered how many native animals such as wombats, echidnas, reptiles, even snakes have succumbed to the floods and what it will do to these populations. Would we even know if this flood event is just another in the sorry state of Australian extinction events.
And what will be the effect of the contaminated, silt laden water on the Great Barrier Reef? No doubt there will be several research programs being planned to get this data. For our sake, (tourism & ecology both) I hope the effect of the floods will be temporary at most and not too deleterious.
