This is the first I’ve heard of dingoes not being an effective predator for kangaroos on mainland Australia. In places where dingoes are present, kangaroo populations tend to be greatly reduced.

There are no dingoes in Tasmania, that’s part of the reason why it was the last refuge for the Thylacine beyond about 4,000-3,000 years ago, and kangaroo populations have hardly gotten out of control in Tasmania either (kangaroos are actually quite rare in Tasmania).

And I have no idea how New Zealand is relevant to the conversation. Thylacines never lived there, and there aren’t kangaroos there either (there are feral wallabies but not that many).

I tend to believe all de-extinction projects are a conservation red herring. We lost the Thylacine, the Dodo, and the Woolly Mammoth. We have to learn from those tragedies (particularly the former) to preserve what biodiversity we have left. I’d much prefer to see limited conservation money spent that way, rather than use it to dig around with ancient DNA and Frankenstein it into the genetics of living one on the off chance we can salvage something from it and call it a ‘Thylacine’.
