Over 800 sample sites were surveyed throughout the Pilbara. These sites represented a cross section of the region's soils, landforms and major geological formations, climate and vegetation types.
Sites were located on and within:

  • current and ex-pastoral leases
  • Aboriginal lands
  • unallocated crown land
  • mining tenements
  • national parks and conservation reserves.

The diversity of plant and animal life was recorded at each site. Most sites were sampled twice in different seasons of the year. A variety of methods have been used throughout the survey. These include pitfall traps for mammals, observation using night vision equipment and a radar gun for bats and plankton nets for stygofauna.The field component of the Pilbara Region Biological Survey was conducted over five years between 2002-2007. Due to the large amount of data collected during the survey, the sorting, identifying, analysing and subsequent interpreting of finding has taken another six years. The botanical component of the survey which is dealing with over 80,000 plant specimens is still ongoing.
