Wet Tropics Vertebrate Pest Risk Assessment Scheme

Research Report
Debra A. Harrison and Bradley C. Congdon
Rainforest CRC researchers undertook a consultancy for the Wet Tropics Management Authority to design a risk assessment process that would establish the relative pest status and potential impact of exotic vertebrates within the Wet Tropics Bioregion. This report outlines the Wet Tropics Vertebrate Pest Risk Assessment Scheme. The Scheme is an Excel-based spreadsheet program that assesses pest status relative to five generic pest species characteristics:  

 
  • Previous pest history;
  • Reproductive and dispersal potential;
  • Ability to capitalise on variation in climate and/or biological events;
  • Ability to vector disease or parasites; and
  • Ability to threaten existing species via predation, competition and/or habitat degradation.
