Landscaping
Landscaping is the first step in the rehabilitation process. Landscaping reshapes the mined out pit, removes pit faces and pit floors, buries large rocks and creates a final surface that blends in with the surrounding forest topography.
Landscaping also provides an opportunity to create drainage controls within the pit.
The surrounding forest has established trees to add structure to the soil, and prevent soil being washed away during rain events. Newly rehabilitated pits don't have this structure yet.
Landscaping design allows water to be captured within the pit and prevents the soil being washed off into surrounding forest.
The final landscaped pit is left 30-40cm below the surrounding forest. This allows the rehabilitation to be at an equal height with the surrounding forest once the overburden and topsoil have been returned.
The rock and wood debris is removed from the pit edges to ensure no barriers between rehabilitation and forest are created.
