We aim to develop rehabilitation of mined land that returns the site to a condition where its landforms, soils, hydrology and flora and fauna are self-sustaining and compatible with the surrounding land use. Rehabilitation works are scheduled to occur progressively as soon as practical after mining disturbance.
Our rehabilitation follows a natural landform design which will be implemented in all final rehabilitation. In addition to the natural landform created, plant species compositions have been selected based on vegetation types of the surrounding natural landforms. The diversity within the vegetation of the post-mining landscape will allow the re-establishment of a variety of vegetation types and formations whilst greatly increasing the value of the rehabilitation for fauna species.
Annual inspections and monitoring of rehabilitated areas occur to assess:
- Soil conditions and erosion;
- Drainage and sediment control structures;
- Runoff water quality;
- Revegetation germination rates;
- Plant health;
- Weed infestation; and
- Pest fauna.
These monitoring events identify any actions are required and the need for management strategies such as weed control or pest fauna management.
To provide habitat and enhance the final land use of the ecosystems, the following activities will be conducted in the rehabilitation areas:
- Installation of nest boxes;
- Translocation of orchid and other threatened flora species; and
- Salvage and reinstalment of habitat trees.
