Welcome to the sometimes complex world of mine rehabilitation! With the increasing awareness of environmental impacts, mine rehabilitation has become an essential aspect of mining operations and is crucial for restoring ecological balance and returning the disturbed lands to a stable and functioning landscape. Here are some key factors in successful mine rehabilitation.
Landform and soil shaping
The aim with soil shaping is to control the flow of water and create natural landforms which promote the establishment of vegetation and reduce soil erosion. On flat ground, we can add hollows for water to collect and on steeper land, diversion bunds and contour banks. As well as assisting with erosion control, soil shaping also assists in creating micro-environments for vegetation growth.
The mining process greatly disturbs the natural soil environment, hence often making it unsuitable for vegetation growth. This can be difficult to overcome, but some measures can be put in place for long-term improvement. Adding ameliorants, organic matter, and balancing the soil chemistry are crucial steps in allowing soil biology to return and fostering the establishment of vegetation. This process can take considerable time and should not be left until mine closure. In our natural environment, soils can take thousands of years to develop, so it’s important this crucial element is considered early.
Establishment of vegetation
Nature needs the soil to be stable before vegetation can occur. Hydromulching, polymer sprays and compost blankets can all be used to effectively establish vegetation cover by stabilising the soil and reducing erosion. Vegetation establishment is critical for restoring ecological balance and providing habitats for native flora and fauna to thrive, however the soil must first be stable, otherwise all efforts will be lost!
Protection of rehabilitated areas
Protecting the land from external disturbances such as grazing animals, feral goats etc. is critical in the early stages rehabilitation. Measures such as stock proof guards on tubestock plants and feral goat fencing are used to safeguard newly established vegetation cover and promote soil development. Another method of protecting the soil is the use of pioneer and cover crop species to restore soil biology, prior to the establishment of final vegetation communities, which can be difficult to establish in highly disturbed soils.
