Rehabilitation Sustainability
 
Alcoa's rehabilitation objective is to re-establish a self-sustaining jarrah forest ecosystem that will fulfil the forest land uses including conservation, timber production, water catchment and recreation. To do this our rehabilitated areas must be capable of functioning as a complete ecosystem. This means that nutrients must be recycled, plants must produce viable seed, and vertebrate and invertebrate fauna must return. Rehabilitated areas also need to be resilient to further disturbances such as fire, insect attack and drought.
 
In consultation with our stakeholders and the wider community we have developed a set of standards, known as Completion Criteria. These Completion Criteria define the standards that must be met to ensure rehabilitated areas are sustainable and able to be managed in a similar way to the surrounding unmined forest.
 
Alcoa's Environmental Department has an extensive research program that continues to investigate many of the issues relating to the sustainability and long-term management of the rehabilitated areas. This research program includes many co-operative projects with the Department of Environment and Conservation (DEC), Kings Park and all of the local universities.

Our rehabilitated forest must be capable of regenerating after normal forest management operations such as thinning and burning.
