About the report

This IR reports progress of a consultancy sub-contract between the Environmental Research Institute of the Supervising Scientist (eriss) and the Key Centre for Tropical Wildlife Management (KCTWM), Charles Darwin University (CDU). The KCTWM has a Head Contract with Parks Australia North (PAN) to develop, in consultation with Traditional Land Owners, a feral animal management strategy for Kakadu National Park. Extracts from the Introduction of the First Progress Report (Whitehead et al 2002, Section 1.0) provides background. The terms of reference (ToR) of the eriss sub-contract (see Section 2.0 for details) are to:

  1. assist with reviews on feral animal abundance and impacts in Kakadu National Park;
  2. help design quantitative models for feral pigs and buffalo capable of incorporating costs of control, incomes from exploitation, and environmental damage, all in relation to animal density;
  3. assist in consultation with stakeholder groups and in the presentation of models and their implications to stakeholders;
  4. help identify and analyse feral animal control options, in particular for feral pigs;
  5. help develop decision support tools to determine trade-offs in decision-making; and
  6. help contribute to the design of adaptive management experiments for feral pig control.

ToR 1 is encompassed in the First Progress Report of the Head Contract. Consultation with Traditional Land Owners is ongoing activity for the duration of the contract (ToR 3). Progress in the development of temporal and spatial population control models (ToR 2) is summarised here (Section 3.0). The remainder of the sub-contract comprise ToR 4–6.
