This habitat has a diverse assemblage of deciduous trees and shrubs as well as abundant herbaceous taxa. Slope: 10 to 25 percent. Aspect: Northeast (generally). Geology: The underlying geology of this area is probably of lower Paleozoic age and characterized as the Octoraro Formation. It includes albite-chlorite schist, phyllite, some hornblende gneiss, and granitized members. Soils: The area where this species occurs is right on the edge of two soil zones that transition from the river’s edge to mesic conditions upslope. The first is generally referred to as Rock Outcrop. This terrestrial matrix in which plants grow is largely exposed underlying rock geology with accumulated outwash, rock decomposition, and organic debris buildup. The second is Mt. Airy (80%) and Manor (20%) Series soils, 25 to 60 percent slopes, extremely stony (MRF). (Source: California Soil Resource Lab/NRCS Official Soil Series Descriptions).
