Rehabilitation - highest and best recovery where full recovery is either not possible or desirable

Maintaining and improving indigenous habitats in our utilised landscapes and aquatic ecosystems is of very high importance to the survival of plant and animal species that cannot be supported by reserves alone. Maintaining and rehabilitation indigenous ecosystems in these areas can also provide essential ecosystem services to society

Examples:

Travelling Stock Routes rehabilitation, New South Wales:
Once used by pastoralists when droving sheep to market, these areas are still used for grazing by landholders. As they are some of the best remaining examples of regional ecosystems in the agricultural landscape, they are now being managed to optimise both native ecosystem management and grazing.

Clarence Floodplain project:
The 'Clarence Floodplain Project' was established in 1997 with the aim of improving the environmental management of Council's flood mitigation infrastructure and addressing some of the past impacts of flood mitigation on floodplain ecosystems.

Sea to Hume Dam Fishways, Murray-Darling Basin Authority
As part of a broader program to restore health to the pre-existing biodiversity of the Murray, the Murray-Darling Basin Authority has installed fishways at 12 weirs and five barrages along the main stem of the Murray to restore passage for fish movement up and down the river.

Landcare movement (all states)
Since the loosely networked Landcare groups started in rural Victoria in the mid-1980s, some 4000 Landcare groups have formed all around the agricultural regions of Australia, with some government funding support. Many groups have been highly successful in achieving more sustainable farming practices to improve soil and water on farms and substantial numbers of trees and shrubs have been planted in agricultural area, improving ecosystem function.

Coastcare (all states)
Modelled on Landcare, in the mid 1990s, the Coastcare program was rolled into the Australian Governments' Natural Heritage Trust Clean Sea Program, with funding of groups starting in the mid 1990s. There are now around 2000 Coastcare groups working to protect and rehabilitate dunes around the country.
