After mining, to reclaim the land, the depression is filled with rocks then the top is filled with loosely graded soil. Introduction of early succession plants is important before big trees can grow. The early succession plants help in the breaking down of the rocks into soil hence making the topsoil deeper to support trees.
Answer:
In general, it is noteworthy to mention that for the restoration of land damaged by mining, a series of activities focused on its recovery can be followed: finish with what is causing the affectation; reduce the effects that are being produced by mining; as far as possible bring the land to conditions similar to those previously; incorporate biotic or abiotic elements that were in the affected lands.
Explanation:
The capacity for the successful restoration of an ecosystem affected by mining before and after the problem, it is necessary to know all the factors that were originally, such as hydrology, geomorphology and soils. It is necessary to know the causes that generated the problem, the composition and the functioning of the ecosystem before the affectation, the information about the regional environmental conditions. Finally, it is necessary to know the native biota that is required for restoration.
