"Breeding threatened mammals in fenced, predator-free areas is a common
conservation strategy in Australia. The method is designed to protect
vulnerable species and breed animals for release into the wild.
But our research – involving a cute, digging mammal known as a woylie –
suggests the strategy may put animals at a distinct disadvantage once they’re
fending for themselves.
We found animals bred in fenced conservation areas, known as “havens”, lost
traits they need to detect and escape predators. It’s likely this made them
less able to survive in the wild.
This unintended downside could jeopardise the survival of endangered species
such as woylies. It shows we must increase investment in managing wild
populations of threatened species, and help animals in havens get accustomed to
predators."
