A large volume of data was collected during the Pilbara Region Biological Survey, which has taken a considerable time to sort, identify, analyse and interpret but for most groups this is now complete. Our results to date include:

  • discovery of several new cryptic gecko species, two prevalent pebble mimicking dragons and several species of sand-swimming skinks
  • collection of 13 species of frog across the arid region
  • identification of 132 non-oceanic species of birds present of survey sites
  • documentation of the geographic range, status and breeding season for 325 bird species as known to occur in the region
  • recording of more than 350 stygofauna species (groundwater fauna), of which more than 300 are newly discovered
  • the collection of more than 1,000 species of invertebrates that live in aquatic ecosystems
  • recording of more than
    • 600 species of ground-dwelling beetles
    • 245 species of ants
    • 375 species of ground-dwelling spiders
    • 22 species of scorpion
  • identification of 11 frog species and more than 140 reptile species
  • recording of 19 small ground-dwelling mammals
  • documentation from recent fossil deposits of a mammal fauna that was compromised of up to thirty six native species.
  • recording of 23 species of bats
  • the collection of more than 80,000 plant vouchers representing about 1,100 species, of which at least 8 are new to science and 25 new to the Pilbara
  • documentation of 103 weeds in the Pilbara of which up to 29 are significant habitat modifying species.

Where to next?

Now that surveying is almost completed, the challenge is to collate and analyse the enormous amount of information that has been gathered over the past years. Once this has been done, we aim to present the information and raw data via NatureMap in formats that can be accessed and used by anyone with responsibilities for or an interest in land management in the Pilbara.
The information and specimens collected through the survey will provide researchers at Parks and Wildlife, the Western Australian Museum and other institutions with material to further their investigations for many years to come.
