Abstract: |
Clay settling areas (CSAs) are constructed on about 2,000 acres of land every year to contain waste clays following phosphate mining. The reclamation of CSAs to foster wetland ecosystems has been proposed for these areas but not yet demonstrated as a viable alternative, due to the lack of natural colonization of species typical of mature wetlands. Clay settling areas planted with wetland trees in an early test of forested wetland viability were revisited after twenty years. Survival and growth of species typical of riverine swamps demonstrated the suitability of planted trees in seasonally wet areas, but the general lack of recruitment does not assure long-term sustainability of the populations. After twenty years planted trees provide additional canopy structure but they are less influential in the development of soil and understory ecosystem components than site-specific exogenous factors. Engineering of CSAs to promote hydrology typical of natural wetlands and supplementing tree planting with understory species are likely to lead to more persistent and diverse wetland communities. |
