Abstract

Abstract Since the costly practice of toxic spoil burial and topsoil replacement during surface mine reclamation are mandated by law, it has become feasible to consider creation of constructed wetlands for wildlife habitat as an alternative mined land reclamation practice on active or abandoned mine sites. This is also a novel approach for metigation of lost natural wetland in the past. Implementation of this concept will require proper baseline information from the biogeochemical properties of constructed wetlands developed on surface mined sites. Baseline data were collected from two wetlands developed on strip mined sites in Alabama. We took samples from each wetland in April and September 1992. Since the naturalization of these wetlands with regard to the spatial variabilities within each wetland were the main objective of this work, a natural wetland developed on undisturbed soil was sampled at the same time so that it could be used as a reference to wetlands developed on disturbed soils. The natural...
