dc.description.abstract Exotic forest pests and pathogens are among the most serious environmental threats to millions of hectares of forested land worldwide. In Great Smoky Mountains National Park (GRSM), high-elevation beech gaps are dominated by American beech (Fagus grandifolia Ehrh.)—a tree species that has been severely impacted by Beech Bark Disease (BBD), a non-native pathogenic complex first confirmed in the Park in 1986. In 1994, a long-term monitoring protocol was established by Park foresters to document patterns of BBD infestation, progression, and host mortality at 10 beech gap plots established throughout GRSM. The analysis of a 23-year dataset supports that the reduction in F. grandifolia basal area is driving significant shifts in forest structure and composition. The decline of the foundational species, F. grandifolia from high-elevation beech gaps will have broad consequences for associated biota, ecosystem function, and potentially, the long-term persistence of beech gaps in GRSM.
