Southern Fleurieu

Biodiversity:  Reducing the impacts of pest animals

High Priority

What is this issue

Over-grazing by kangaroos, rabbits and/or deer (unmanaged).

Impacts of the issue

  • Increased total grazing pressure
  • Decline in habitat condition due to loss of palatable native plants
  • Poor recruitment of native species
  • Increased erosion risk


  • Insufficient control of pests
  • High population growth rates of pest species
  • Increased availability of water in the landscape
  • Historical introductions
  • Farm escapees
  • Substantial harbour areas in this subregion (e.g. management of kangaroos in conservation areas)


  • Social lack of acceptability of pest control (particularly kangaroos) e.g. in Southern Fleurieu
  • Difficulty of control including; red tape, danger involved in control, restrictions on control, particularly on Public Lands
  • Less well-developed networks
  • Restrictions to some controls in residential areas
  • Often not cost effective to harvest/control

Who plays a role

  • Adelaide Mount Lofty Ranges Natural Resources Management Board
  • Agricultural Bureaus
  • Biodiversity related non-government organisations
  • Consultants
  • Department of Environment, Water and Natural Resources
  • Farm/Industry supporters
  • Horse SA
  • Industry Groups
  • Landholders
  • Local Action Planning and Landcare groups
  • SA Murray-Darling Basin Natural Resources Management Board 

Strategies and Actions

Build landholder capacity to manage pest animal species

  • Provide training in pest animal control methods (e.g. warren destruction to improve the effectiveness of rabbit biological control)
  • Connect landholders to pest control service providers, targeting absentee landholders
  • Facilitate community discussion on the impacts and management of over-abundant native animals, and raise awareness of control programs

Improve planning and coordination of pest control across tenure

  • Undertake coordinated control across property boundaries, targeting high value biodiversity assets
  • Monitor the condition of biodiversity assets to guide prioritisation of control activities
  • Monitor population density and growth rates of pest animals

Using policy/market instruments to manage the impact of over-abundant native species (e.g. kangaroos)

  • Review the Over-abundant Native Species Management Strategy (AMLR) in regard to its potential application SA MDB
  • Incorporate strategies for managing over-abundant native species into National Park Management Plans
  • Facilitate community discussion on the use of shooters for pest control on public lands
  • Investigate alternative options for the management of nuisance native fauna (including corellas and kangaroos), such as sacrificial areas
  • Investigate and promote commercial harvesting and tourism/market opportunities for kangaroo meat

Manage the impacts of deer/pigs and prevent releases/escapes of farmed populations into wild populations

  • 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
