Abstract

The brush-tailed rock-wallaby (Petrogale penicillata) is now extinct west of the Great Dividing Range, apart from remnant populations in the Warrumbungles and at Mt Kaputar. Previous genetic analysis has identified deep genetic subdivisions within P. penicillata, but samples from Mt Kaputar were not included. Mitochondrial DNA sequences obtained from Mt Kaputar and the Warrumbungles clustered within the Central ESU, extending its distribution north of the Hunter River onto the north-western slopes adjacent to populations of the Northern ESU. These highly threatened western populations are the only P. penicillata persisting in semiarid conditions. This makes them of particular value to the long-term survival of the species and their conservation should be a priority.
