Soil Erosion can be defined as a method of detachment transportation of surface soil particles from its origin and deposition at some other area. 6. Soil loss refers to that material actually removed from the particular hill slope or slope segment which may be less than erosion due to onsite deposition in micro- topographic depressions

Habitats are created using original rocks and timber material encouraging invertebrates insects and other fauna to recolonise the area. Reshaping of mined land blends mined areas into the surrounding landscape reduces the likelihood of erosion by reducing slope angles and lengths and allows natural drainage patterns to be re-established

Surface cover is a major factor to control erosion because it reduces the impact of raindrops falling on bare soils and wind removing soil particles. It also reduces the speed of water flowing over the land. Erosion risk is significantly reduced when there is more than 30 soil cover. Total cover is achievable for many graing and cropping systems
