So you want to cat-proof a bettong: how living with predators could help native species survive

"When we release a group of endangered animals into the wild, we always hope
they will survive. They usually don’t. We find bilby carcasses under bushes,
bettongs ripped apart by feral cats, and tufts of rock wallaby fur in fox
scats.

Over the last 25 years I’ve seen the devastation caused by introduced foxes and
cats firsthand during attempts to conserve our threatened mammals. At one of my
research sites, Arid Recovery, we have tried again and again to protect
bilbies, bettongs and wallabies outside fences.

Unfortunately, our native animals have not co-evolved with these canny
predators and simply don’t have the anti-predator behaviours or physical traits
needed to avoid them.

So what to do? After years of discouraging results, we’re trying something new.
We want to help our native marsupials evolve to become warier and better at
surviving. Not in fenced-off sanctuaries – but in the wild, alongside these
extraordinarily clever predators."
