Key strategies include the creation of Safe Havens or predator-free areas providing a refuge from predators such as cats and foxes, which are responsible for the decline of many native species.

These small creatures share several characteristic physical features: a plump, arch-backed body with a long, delicately tapering snout, large upright ears, long thin legs, and a thin tail. The evolutionary origin of this group is unclear, but they share characteristics from both carnivorous and herbivorous marsupials.
