Any landfill or other reclamation site will revegetate naturally given time. What happens naturally may seem to be the province of the naturalist, and little to do with the practical steps which have to be taken when we want to hasten the revegetation process artificially, which many will think is the province of the landscape architect and engineer. Yet these two processes are indissolubly linked, because they are both the outcome of the interaction between the ecological characteristics of the site and the natural requirements of plants. We cannot get effective reclamation unless we understand the ecology of the site and of the materials we want to use. This can best be illustrated by a detailed examination of the revegetation of any distinctive type of waste material. On china clay waste, natural revegetation is very slow, and earlier attempts to revegetate it artificially failed. Yet because of the nature of soil/plant ecosystems, all this is due to one major problem - lack of plant nutrients, especially nitrogen - which can be overcome simply and economically by a combination of chemical and biological techniques. It may appear that all sites are unique, and that to ensure success elaborate solutions will always be required. It is true that to achieve elaborate endpoints rapidly, extensive manipulations may be required, but a survey of different sites shows that it k when proper ecological understanding is combined with appropriate technology, that effective and self-maintaining end products are produced economically.
