Plants and animals need food, water, shelter, oxygen, light and other resources to survive and reproduce.

These resources provide the basic elements of habitats. They sustain and help protect life from 'bad' weather, predators, disease and other threats.

To conserve our native plants and animals, it is essential we:

  • protect and manage enough habitat to allow native plant and animal populations to live and grow.
  • Programs to achieve this include purchasing and managing nature reserves, and advising landholders who want to protect remnants of native bushland.
  • increase the amount of 'life resources' in habitats where there are not enough to allow populations to live and grow. To achieve this, the department carries out a wide range of work including revegetation to expand and protect resources for plants and animals, such as planting 'corridors' to connect isolated areas of bushland.


Revegetation is an important tool for nature conservation, including:

  • buffering remnants of native bushland against wind-blown farm fertiliser, herbicides and weed seeds;
  • creating completely new habitat. For example, where woodland habitat for birds is short, we can increase the area of woodland by planting more trees, preferably with an understorey of shrubs
  • connecting patches of bushland so that a particular target animal can move more easily between the two areas, increasing access to resources and mates.

In agricultural areas, revegetation can also be used to protect and create other land uses. For example, farmers may use revegetation to:

  • stop a salt scald spreading
  • help control wind or water erosion
  • create protected areas for domestic stock.

The innovative use of local native plants helps conserve existing biodiversity values but can also create production opportunities that would otherwise be overlooked.
