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

  • Biosecurity SA
  • Department of Environment, Water and Natural Resources
  • Environment Protection Authority
  • Primary Industries and Regions 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

  • Maintain lake levels by ensuring there is an allocation in storage to underpin critical human water needs
  • Address the way water is delivered to the Lakes

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‚Äôs 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 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

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

  • Identify and target high-risk pathways of entry for pests and diseases
  • Develop and implement effective entry and border control procedures and techniques for detecting high risk pests and diseases
  • Apply effective containment protocols for individuals, institutions and industries that use potentially invasive organisms
  • Collaborate across state government agencies to deliver effective and efficient surveillance, management and control programs for biosecurity risks
  • Develop and implement management plans and programs to contain spread and reduce the impacts of priority pests and diseases
  • Partner with industry, community groups and advisory boards to improve outcomes from established pest and disease management
