Abstract
The subalpine red spruce-Fraser fir (Picea rubens-Abies fraseri) forest on the summit of Mount Rogers in southwestern Virginia, the northernmost extension of this southern Appalachian forest type, was intensively sampled to obtain quantitative data on composition and structure of all strata of vegetation. In addition, data were obtained on soil chemical and physical characteristics. Although 5 tree species were present, fir dominated all size classes with spruce the only important associate. Oxalis acetosella and Dryopteris campyloptera made up > 95% of the total herb cover. The shrub stratum was poorly developed with just 3 spp. represented. This community is ecologically similar to other southern Appalachian spruce-fir forests.
