Changes in Forest Overstory Composition on the Southwest-Facing Slope of Beanfield Mountain in Southwestern Virginia

A former oak-chestnut forest community on the southwest-facing slope of Beanfield Mountain in the Mountain Lake area of southwestern Virginia, previously sampled in 1939 and 1969-70, was resampled during the summer of 1993 to assess the successional changes in forest overstory composition that have taken place following the chestnut blight. In 1939, an oak complex dominated by white oak (Quercus alba), chestnut oak (Q. prinus), and red oak (Q. rubra) had replaced the original oak-chestnut forest. The 1969 70 study found that pignut hickory (Carya glabra) had become the leading dominant on the slope, with red oak and chestnut oak the most important codominants. However, by 1993 hickory had decreased in importance, and red maple (Acer rubrum) had become a canopy codominant. Red oak and chestnut oak were still the dominant oaks, but black birch (Betula lenta) also had become a consistent component of the community. As such, nearly seventy-five years following the blight, oaks have maintained their codominant status. Hickory is less important than in 1969-70, whereas red maple and black birch are more important.
