ABSTRACT: Characteristics of woody vegetation were compared across six different southern Appalachian cove forests. Trees greater than 6.35 cm dbh were point sampled and regeneration was tallied on 25 m2 subplots at all study sites. Overstory composition and structure differed between secondary and old-growth sites, which were dominated by yellow-poplar and eastern hemlock, respectively. Mean species richness and density-based diversity indices were higher in the secondary sites for both the overstory and regeneration strata. Shade tolerant species were favored in the regeneration strata at all sites, and yellow-poplar regeneration was rare throughout the study.
