Biodiversity Offset Areas are maintained under the Biodiversity Offset Management Plan (BOMP) for biodiversity conservation and enhancement purposes. The BOMP provides a framework for the implementation of ecological management actions, regeneration and revegetation strategies, controls and monitoring programs.
The conservation management objectives of our Biodiversity Offset Areas (BOAs) are to:
- Conserve and enhance native vegetation and habitats for a range of threatened and migratory species, endangered populations and threatened ecological communities across the BOAs;
- Improve the habitat values and habitat connectivity of the remnant native vegetation within the BOAs;
- Successfully establish an additional 1,104 hectares of treed vegetation within areas of existing Derived Native Grassland in the BOAs;
- Maintain 330 hectares of the BOAs as existing Derived Native Grassland; and
- Implement and maintain sustainable agricultural practices within the BOAs.
To date, the following achievements have been met in the BOAs:
- Regeneration has commenced in over 136 hectares of the BOAs;
- Natural regeneration has been documented in over 263 hectares of the BOAs; and
- 399 hectares across the Mangoola Open Cut BOAs has commenced revegetation/regeneration.
Biannual (twice a year) inspections of regeneration/revegetation areas will be undertaken over the life of the project and will assess:
- The condition of site features such as fences and access tracks;
- Evidence of erosion;
- Condition of revegetation/regeneration strategies;
- Weed infestations; and
- Evidence of pest fauna.
The Mangoola Ecological Monitoring Program is conducted on an annual basis and includes:
- Monitoring of remnant vegetation within the Mangoola Biodiversity Offset Areas;
- Monitoring of regeneration/revegetation areas within the Mangoola Biodiversity Offset Areas;
- Fauna monitoring;
- Specific threatened species monitoring;
- Stream health monitoring;
- Nest box monitoring;
- LFA monitoring; and
- Mollusc monitoring.
