Mammals - Barrow Island is recognised as an important refuge for native mammal species that have either declined in numbers or become extinct on the mainland. The island supports 13 species of resident terrestrial mammals, with a further two species of bat recorded as vagrants to the island. All of the terrestrial mammal species of Barrow Island, except bats, were either trapped or observed within the proposed Development area. Bats are likely to forage in the Development area, but have not been recorded. All of these species are widespread on the island, with the exception of the water-rat which is confined to coastal areas. There are no distinctive habitat features within the proposed Development area that are likely to support unusually high population densities of any mammal species. The small black-flanked rock-wallaby population does not occur within the proposed Development area. Reptiles and Amphibians - The reptile and amphibian assemblage on Barrow Island is depauperate in comparison with the herpetofauna of the adjacent mainland. Barrow Island is home to 43 species of reptiles comprising dragons, legless lizards, geckoes, skinks, blind snakes, monitors, snakes and one frog species. Most of these species, or their habitats, are widely distributed on Barrow Island. Twenty-seven species, or more than half of the terrestrial reptiles known to occur on Barrow Island, have been recorded in the vicinity of the Development area. The reptile assemblage along the proposed domestic gas pipeline route on the mainland is expected to be degraded by feral predators and habitat alteration through livestock grazing. The EPBC Act-listed Pilbara olive python is restricted to rocky habitats in the Pilbara and is not expected to occur in the sandy habitats along the domestic gas pipeline corridor.
