"If you want to see some of Australia’s most charismatic threatened mammals
such as bilbies, boodies and stick-nest rats, chances are you’ll have to go to
a zoo – or a safe haven.
What’s a safe haven? An area safe from feral predators, such as islands too far
offshore for foxes to swim to, or mainland sites ringed with cat- and fox-proof
fences.
Recent research has suggested we can now take 29 species off the threatened
list, thanks in large part to safe havens. But unfortunately, it’s not that
simple, as we’ve found in establishing several havens. Safe havens are not the
same as the wild. When we try to reintroduce animals outside the fences, they
disappear down the maws of cats and foxes.
Yes, they fend off extinctions. But safe havens require ongoing management,
which is expensive, challenging and rarely guaranteed long term. We should not
rely on them to take species off the threatened list."
