Observation Narrative
Habitat is a seasonally flooded upland which normally holds water during the spring and winter (and sometimes during wet periods in summer and fall). Similar habitats and vegetation are scattered in the Piedmont on diabase, gabbro, slate and other substrates which develop hardpan subsoils. Although Quercus phellos is the characteristic tree regardless of substrate, Quercus lyrata is a typical component of southern piedmont depression swamps on mafic substrates such as gabbro or diabase. There are few other floristic indicators of substrate in these habitats, perhaps because the hydrology and density of surface soils inhibits uptake of macronutrients by shallow rooted herbaceous plants.
Plot location: Upland depression swamp at corner of Kerr Reservoir Property, 0.95 miles WNW of jct. US 15 and Rt. 699, and 0.15 miles east of Hogan Creek.
