Observation Narrative
Rich mesophytic forest on a ravine slope downcutting into Tertiary shell deposits. Soils are circumneutral, with exceedingly high calcium levels and 100% total base saturation. Very small patches of this occur throughout the upper Black Swamp ravine system. Huge numbers of Acer barbatum seedlings were present on the survey date. Spring revisit needed, as any ephemerals present in this habitat would not be detected at such a late date.
