Small mammals are disappearing from Booderee National Park. Introduced animals such as foxes are killing small native mammals, contributing to declines and extinctions.. Southern brown bandicoots and eastern quolls were once very common but these animals had not been seen in the park for many years. There has been significant pest management for many years in Booderee, and in 2014, 35 long-nosed potoroos, 28 southern brown bandicoots and 60 eastern quolls were reintroduced. Initially, all the animals survived but now only the southern brown bandicoots and long-nosed potoroos continue to survive in the park. Ongoing management is needed for small mammals to survive here into the future.
