The approach to rehabilitation often follows one of two main strategies, these being: (1) using a surface cover of soil or soil-like material to provide a plant growth medium, or (2) improving the physical and/or chemical properties of the residue using amendments (e.g.
For materials exhibiting less extreme characteristics (more consistent with soil-like properties), planting directly into the ameliorated, amended residue surface can be a more suitable alternative (Mendez and Majer 2008).
