Observation Narrative
Seepage swamp in ravine at NW boundary of Park. Soils are calcareous and nutrient-demanding species (e.g., Carex bromoides ssp. bromoides, Packera aurea, Bidens laevis, Pilea fontana) have high cover. Trees are young - possibly logged in the recent past. Part of large, high quality occurrence in ravine. Other areas of this ravine bottom have dense cover of Asimina triloba. Little cover of exotics observed.
