Project Summary Update

Projects Aims

  1. To count saltwater crocodiles in the Kimberley region;
  2. To survey Kimberley waters that have never been surveyed for crocodiles in partnership with Indigenous Rangers e.g. Drysdale River and Walcott Inlet
  3. To calculate population growth rates in river systems that have been surveyed previously
  4. Study geographical variation in abundance and population growth rate between rivers systems

To identify critical habitat for saltwater crocodiles in the Kimberley region.

Proposed Methods

  • Boat-based spotlight surveys broadscale and standardized
