Observation Narrative
Plot provides an interesting contrast to PEDL001P. The herbaceous component is only slightly better developed but does contain scattered individuals of species characteristic of dry-mesic calcareous forests, such as Bromus pubescens and Muhlenbergia tenuiflora. Structurally the vegetation is more heterogeneous, with fewer large trees and many more subcanopy individuals < 10 cm dbh. Woody regeneration dominates the ground stratum, but here the most abundant species is Acer saccharum, seedlings of which are generally < 10 cm tall. The soil is much thinner and contains abundant dolomite cobbles; outcrops are exposed where leaf litter is absent. Stand has experienced considerable disturbance (apparently wind damage); small branches, large limbs, and bole fragments all compose coarse woody debris.
From flagged Quercus muhlenbergii (47 cm dbh; adjacent to triplet clump of Acer saccharum): 7 m @ 300 deg to stake A.
