10. Refugia in Western Australia (continued)
10.6. Reference number WA6
Refuge area: Smaller islands of Shark Bay
Biogeographic region: Carnarvon
Type of refuge: Islands
Lat./Long. 26°31’S / 113°39’E; 26°32’S / 113°46’E
Quality of refuge: Highly significant (4)
Area (km²): <100
Chief refuge value
Isolated islands free of introduced predators and land-use changes.
Small islands of 160 ha (Salutation) and 19 ha (Baudin).
Mammals: Greater stick-nest rat Leporillus conditor (E) reintroduced to Salutation Island in July 19904, 5.
Reptiles: Baudin Island Spiny-tailed skink Egernia stokesii aethiops (V) (Baudin Island).
Baudin Island Spiny-tailed skink Egernia stokesii aethiops (Baudin Island).
Egernia kingii (confined to Three Bays Island in Freycinet Estuary), 200 km north of nearest mainland population5.
Other significant species
Breeding and roosting areas for many birds, both seabirds and terrestrial species5.
Introduced species, particularly predators. House mice are present on some islands. Increased competition from other reptiles and/or accelerating weathering from climatic change may threaten the skinks on Baudin Island3.
Both Baudin and Salutation Islands are Nature Reserves.
