Biodiversity:  Managing pest animal and disease risk

Medium Priority

What is this issue

New and emerging pests and diseases

Impacts of the issue

Decline in ecosystem health or potential loss of significant populations of native species due to competition or disease. 


  • Unintended introductions (via people, plant material, animals, machinery and vehicles)
  • Poor biosecurity or quarantine failures
  • Climate change (shift in climatic envelopes & susceptible areas)


  • Difficulty in predicting when and where incursions may occur and what controls will be required
  • Control options may be limited
  • Spread may be rapid

Who plays a role

  • Department of Environment, Water and Natural Resources
  • Environment Protection Authority
  • Primary Industries and Regions SA - Biosecurity SA
  • SA Health
  • SA Murray-Darling Basin Natural Resources Management Board 

Strategies and Actions

Early detection and containment of new pest and disease incursions, and eradication whenever possible

  • Establish surveillance programs for the early detection of new threats
  • Develop, implement and exercise response plans and procedures for the containment and eradication of priority pests and diseases
  • Build and maintain an emergency response framework to deliver effective whole of government responses to new incursions
  • Conduct emergency responses to new incursions in a rapid, professional and effective manner

Work together with industry and the community to enhance biosecurity

  • Establish effective institutional arrangements that engage all relevant government, industry, community groups and advisory boards
  • Raise awareness of people’s responsibilities in preventing the arrival and spread of pests and diseases
  • Engage industries and communities in surveillance, detection, incursion responses and recovery plans
  • Partner with land managers and aquatic operators in managing priority pests and diseases

Respond to pest and disease threats through a coordinated and effective biosecurity system

  • Assess and prioritise biosecurity risks for all industry sectors, the environment and public amenity within the Region
  • Utilize the as required the legislative measures and powers to effectively deal with prevention, monitoring, control and eradication of declared pests and diseases
  • Participate in the assessment of government capabilities, including diagnostic and research capacities and address deficiencies on a priority basis
  • Contribute to the development and maintenance of an effective biosecurity system with a focus on science, risk assessment, information management, planning, training and communication
  • Have a strong influence on the development of state and national biosecurity programs and policies

Manage the spread of pests and diseases to reduce economic, social and environmental impacts

  • Undertake a review of current extension material available regarding the management deer
  • Undertake a regional community attitude survey. To gain a better picture of current feral deer numbers and related management issues (including disease spread)
  • Participate in the review the State deer policy and management strategy including an audit of deer farms and containment capacity of deer
  • Participate and review outcomes of the national review of deer research and management
  • Review and influence/develop policy on pigs to reduce releases/escapes
