Examining the Cover and Composition of the Successional Vegetation Mosaic of Pre-SMCRA Mined Landscapes in Southeast Ohio

This research examined 10 similar surface coal mines in southeast Ohio to assess the factors broadly influencing the cover and composition of the successional vegetation mosaic. Transects were surveyed on opposing north- and south-facing aspects within each mine to comprehensively characterize the vegetative community. Statistical analysis strongly indicated that measures of vegetation cover were almost exclusively associated with edaphic properties such as soil pH and electrical conductivity. In clear contrast, species richness and the composition of the vegetative community were influenced primarily by physical landform features and the size and shape of mine extents. While some features of surface mines may act as barriers to the dispersal of native species, the element of distance is the primary limitation to natural succession. Areas furthest from the functional edge seem to be more readily occupied by non-native species once conditions improve, representing a missed opportunity for native establishment and may act as a barrier to future establishment of natives. These results may begin to simplify issues for understanding the long-term recovery of mine lands, in terms of the goals of reclamation and restoration. Furthermore, it highlights the need for incorporating more ecologically-based objectives and practices into landscape planning and management.
