The shrub layer varies from moderately sparse in portions of the south segment to very thick in the north. The most common shrub is the nonnative European buckthorn, which is found as mature shrubs, saplings, and as a carpet of seedlings in other areas. Natives found in the shrub layer at least occasionally include boxelder saplings, black raspberry, common elderberry, black cherry, and prickly gooseberry. The ground layer is somewhat species poor, but is largely composed of native species. The most common of these include Pennsylvania sedge, Virginia creeper, white snakeroot, enchanter's nightshade, poison ivy, and false Solomon's seal. The most prominent nonnative forb here is deadly nightshade, which is found only occasionally. Overall, this community is of moderate quality, but has good potential for recovery if actively managed. This is particularly true for the south segment.
