The Pedra Branca skink (Niveoscincus palfreymani) is endemic to Tasmania and is restricted to the rocky islet of Pedra Branca, situated 26km off the south coast of Tasmania. The species belongs to the largest and most diverse family of reptiles in the world, however, because of its remote geographic isolation, little is known of the biology or ecology of the species.
As Pedra Branca Island is the only known location for the skink, the entire island is critical to the survival of the species.
