Oil and natural gas companies are required by provincial regulations to return lands they disturb to a self-sustaining natural state as close as reasonable to its original condition. Reclamation includes:
- Contouring and erosion control: Disturbed surface areas are re-contoured to blend with the original landform. Adequate erosion control will provide for site stability and generally is achieved by successful revegetation.
- Re-vegetation: The establishment of a self-sustaining native plant community is a benchmark of reclamation success, including the control of noxious weeds.
- Reclamation certification: Following reclamation, the landscape is evaluated to ensure there are no erosion or drainage issues, topsoil quality and quantity is confirmed, and the health of vegetation (e.g., plant density, height, productivity, diversity, etc.) is adequate.
