Observation Narrative
The rocky, SE facing slope supports dry woodland vegetation, occurring below the open outcrop documented by plot SNP63. The abundance of Fraxinus americana, Carya spp., Phacelia dubia var. dubia, Muhlenbergia sobolifera and other species appear typical of dry, low elevation woodlands on greenstone. The cover of Phacelia dubia var. dubia was estimated conservatively based on the abundance of dry inflorescence remnants visible in the plot; in all likelihood the actual vernal cover of this species probably exceeds 25%.
Plot location: About 40 m upslope of the Knob Mountain Trail on the southeast slope of the northeasternmost "knob" of Knob Mountain, ca. 0.7 mi. west of Matthews Arm Campground.
