Threatened species, ecological communities and threatening processes

Conservation and recovery of threatened species and ecological communities depends upon the preparation and implementation of recovery or action plans. For such plans to be effective, they need to clearly define the problems associated with a species or ecological community as well as have adequate research techniques to address the identified problems.

The approach that DEWNR takes with recovery planning is aligned with the Commonwealth's Environment Protection and Biodiversity Conservation Act.

Threatening processes decrease the resilience of ecosystems and populations. Science helps to prioritise which threatening processes to address.

Examples of research within DEWNR to underpin the recovery of threatened species and ecological communities are diverse and include:

  • defining habitats for a range of threatened plant and animal species
  • determining reproductive cycles and population dynamics for many threatened species
  • improving understanding of the responses of plant and animal species, and ecological communities, to changes in intensity, extent and frequency of bushfires
  • improving our understanding of pest plant and animal species, and their interactions with threatened species and ecological communities
  • partnering to merge innovative science, practical on-ground action against threats and Anangu ecological knowledge to bring the warru back from the brink of extinction
  • determining daily food intake rates of threatened birds to calculate total area of feeding habitat required for populations of known size
  • identifying effective population monitoring techniques for species with different life histories and life-cycle parameters
  • determining germination and recruitment requirements of plant species
  • partnering in the global Millennium Seed Bank project to ensure conservation of native plant seed stock
  • examining population genetic diversity and determining techniques to maintain and/or improve genetic diversity for captive and reintroduced populations
  • determining conservation status of species and ecological communities in South Australia
  • running DEWNR's marine threatened species program and its projects.
