- Abstract
Appalachian forests are threatened by a number of factors, especially introduced pests and pathogens. Among these is <italic>Phytophthora cinnamomi</italic>, a soil-borne oomycete pathogen known to cause root rot in American chestnut, shortleaf pine, and other native tree species. This study was initiated to characterize the incidence of <italic>P. cinnamomi</italic> on surface mined lands in eastern Kentucky, USA, representing a range of time since reclamation (10, 12, 15, and 20 years since reclamation). Incidence of <italic>P. cinnamomi</italic> was correlated to soil properties including overall soil development, as indicated by a variety of measured soil physical and chemical parameters, especially the accumulation of soil organic carbon. <italic>P. cinnamomi</italic> was detected in only two of the four sites studied, aged 15 and 20 years since reclamation. These sites were generally characterized by higher organic matter accumulation than the younger sites in which <italic>P. cinnamomi</italic> was not detected. These results demonstrate that <italic>P. cinnamomi</italic> is capable of colonizing reclaimed mine sites in Appalachia; additional research is necessary to determine the impact of <italic>P. cinnamomi</italic> on susceptible tree species at these sites.
