Conservation Systematics of the Western Pilbara Fauna

Divers collecting at the Montebello Islands – Nerida Wilson

The Pilbara landscape is ancient and diverse, where animals have been evolving and adapting for millions of years. Surrounded by deserts and the ocean, it is an isolated region where many species are awaiting discovery and description.

To document new species from the Pilbara, WA Museum (WAM) researchers will sequence DNA from many animal groups across the Pilbara and from offshore marine areas, using these data to speed up the process of systematics.

Thousands of specimens will have parts of their genome sequenced, providing a huge database

These data will help researchers identify new species, understand how these new species arose, and assess their connectivity to nearby areas. This will assist managers to conserve the natural heritage of this region.
WAM curators will publish descriptions of new species in the scientific literature. Information about new species will also be shared more widely on the WAM website.

Specimens will be documented, and maintained in the Museum’s collections for posterity to help safeguard our natural heritage.

Sequence data will help to determine the area that species inhabit. This can inform the conservation status of species, which is particularly important for rare local species that are susceptible to extinction.

Achievements to date

A team of scientists has been sequencing specimens since 2014. Groups being focused on to date include trapdoor spiders, scorpions, pseudoscorpions, skinks, mangrove birds, land snails, volutes, oysters, octocorals, hard corals and sponges.

Field trips have been carried out along the coastal Pilbara (from Broome to Exmouth), including the Great Sandy Islands, the Montebellos Islands, and Karijini and Millstream-Chichester National parks.

There are four PhD students working in collaboration with the project, focused on diverse taxa including; mammals, trapdoor spiders, marine snails and subterranean crustaceans.

Over 60,000 DNA sequences have been produced to date. We are assessing species against the IUCN Red List criteria to determine if conservation action is required. The results of these assessments, and species pages detailing the biology of the focal taxa can be found at http://museum.wa.gov.au/online-collections/projects/ncb.
