Observation Narrative	Site is part of an extensive, rocky diabase "flatwoods" supporting a relatively old stand of dry, species-rich oak-hickory forest. Soils in this area have a distinct fragipan of montmorillonite clay and alternate between being rock-hard during dry periods and waterlogged during wet periods. This plot is located on a somewhat xeric, boulder-strewn "crest" vegetated with an open stand of mixed oaks, hickories, and white ash. Cercis canadensis is a common shrub and the herb layer is dominated by xerophytic graminoids, particularly Muhlenbergia sobolifera. Composition is fairly typical of the overall stand.
