“…We had expected to see an exponentially decreasing curve for measures of species density and richness with increasing distance from the forest edge (Harper et al 2005). This reversed pattern of woody seedling survival has been observed at this site with introduced seedlings (Gilland & McCarthy 2012) and is the subject of ongoing research to attempt to elucidate the mechanism driving the pattern.…”

Surface mining for coal represents one of the dominant forms of anthropogenic disturbance to forests of the eastern United States. Reclamation methods adopted under federal law in the 1970s have led to a state of arrested succession, failing to achieve pre‐disturbance conditions. New methods of reclamation have been proposed with the goal of returning mined land to its former forested state through the use of compaction reducing techniques that significantly increase fine‐scale heterogeneity. The Forestry Reclamation Approach creates topographic heterogeneity by loosely dumping overburden material into large piles to serve as a tree‐planting medium. We examined the effect of fine‐scale topographic relief, soil physical properties, and reclamation method on early plant community development on a mine site in eastern Ohio. We sampled plots at four microtopographic positions and three distances from the remaining forest edge in both experimentally and traditionally reclaimed areas of a surface mine. Multivariate analysis of variance (ANOVA) on distance matrices indicated significant differences in plant community composition among microtopographic positions and reclamation methods. Microtopographic positions also exhibited significant differences in measured soil properties significantly affecting plant community composition. Plots in the traditionally reclaimed areas had no woody plant colonization, indicating arrested succession common to sites reclaimed using traditional methods. Our results suggest that the creation of topographic heterogeneity at the time of reclamation markedly accelerates ecological succession and promotes enhanced plant community diversity. Expanded application of the methods used here could allow for a faster return to the former forested state of mined lands than traditional reclamation methods.

“…Gilland and McCarthy (2012) found that chestnut seedlings planted near the edge of existing forest (within about 16 feet) showed significantly lower growth and survival than seedlings planted away from the forest edge (75 to 150 feet). They also found that chestnuts fared better when some ground cover was present, and that seedlings survived better when planted on the sides of end-dumped FRA piles than when planted on the tops of the piles.…”

“…It not only changes the original topography but also exhibits a high bulk density (1.5~1.9 g cm -3 ) that is not suitable for plant growth (Song & Bai, 2000). The current research on the dumps is mostly focused on the properties of dumped materials (Koner & Chakravarty, 2015;Rubinos, Spagnoli, & Barral, 2015;Wang, Li et al, 2017), the spatial variability of dumped materials (Wang, Zhang, Bai, & Guo, 2015;Wang, Lu et al, 2018), and revegetation (Gilland & McCarthy, 2012;Larkin et al, 2008). However, the effects of different compaction degrees on surface runoff and the changes in the volumetric water content of a soil profile in a coal mine dump are less studied.…”

The use of heavy machinery during opencast coal mining can result in soil compaction. Severe soil compaction has a negative impact on the transport of water and gas in the soil. In addition, rainfall intensity has traditionally been related to soil surface sealing affecting water transport. To assess the effects of rainfall intensity and compaction on water infiltration and surface runoff in an opencast coal mining area, the disturbed soils from the Antaibao opencast mine in Shanxi Province, China, were collected. Four soil columns with different bulk densities (i.e., 1.4 g cm‐3, 1.5 g cm‐3, 1.6 g cm‐3, and 1.7 g cm‐3) were designed, and each column received water five times at rainfall intensities of 23.12, 28.91, 38.54, 57.81, and 115.62 mm hr‐1. The total volume of runoff, the time to start runoff, and the volumetric water contents at the depths of 5 cm, 15 cm, 25 cm, 35 cm, 45 cm, 55 cm, and 65 cm were measured. Under the same soil bulk density, high rainfall intensity reduced infiltration, increased surface runoff, and decreased the magnitude of change in the volumetric water contents at different depths. Under the same rainfall intensity, the soil column with a high bulk density showed relatively low water infiltration. Treatments 3 (1.6 g cm‐3) and 4 (1.7 g cm‐3) had very small changes in volumetric water contents of the profiles even under a lower rainfall intensity. Severe soil compaction was highly prone to surface runoff after rainfall. Engineering and revegetation measures are available to improve compacted soil quality in dumps. Our results provide a theoretical basis for the management of land reclamation in opencast coal mine areas.
