Introduction
MEC Case Study: Helping Restore Mined Land for Future Handover
Project Stream: Execution
Project Stage: Environmental Management, Reporting & Monitoring Compliance Auditing
Type of Mine: Open Pit
Region: Western Australia
Commodity: Bauxite
The Challenge
A major bauxite producer required botanical monitoring across rehabilitation areas established 25 to 30 years ago to assess progress towards approved mine closure and completion criteria.
The challenge involved relocating historical monitoring plots within dense native vegetation and accurately assessing ecological recovery against surrounding undisturbed ecosystems. The outcomes would help determine whether rehabilitation areas were progressing towards eventual handback to the State, reducing long-term environmental liabilities and supporting future operational approvals.
The Approach
1. Large-Scale Botanical Monitoring: MEC mobilised a dedicated team of ecologists to undertake a large rehabilitation monitoring program across two mining operations during the spring survey season.
2. Accurate Ecological Assessment: Despite challenging terrain, dense revegetation and variable weather conditions, the team successfully relocated historical monitoring plots and completed detailed flora assessments using standardised monitoring methods.
3. Quality Data Collection & Reporting: Thousands of botanical observations were recorded, supported by GPS data, photography and taxonomic verification, before being compiled into high-quality reporting for client submission.
4. Experienced Environmental Delivery: By combining experienced Principal Ecologists with Graduate Ecologists, MEC delivered consistent field methodologies, robust data management and high-quality environmental reporting across the entire program.
The Outcome
- Rehabilitation monitoring completed across two major mining operations.
- High-quality environmental data delivered with minimal revisions required.
- Client objectives achieved, supporting long-term mine closure planning.
- MEC strengthened its capability in delivering large-scale rehabilitation monitoring programs.
Key Impact: By providing accurate ecological monitoring and reliable environmental reporting, MEC helped the client progress rehabilitation areas towards future completion criteria and eventual land handback, reducing long-term environmental liabilities and supporting sustainable mine closure.
Next Steps
Following successful project delivery, the client has invited MEC to support an expanded rehabilitation monitoring program in 2026. The proposed program would more than double the survey scope and environmental team, building on the successful partnership established during this project.
MEC: Delivering practical environmental solutions that support responsible mining, successful rehabilitation and sustainable mine closure.
