Observation Narrative
Plot located in a classic Betula lenta-dominated boulderfield woodland on a coarse sandstone debris field. Boulders range in size from <1m to >4m across. No mineral soil is present. Beneath the stunted canopy, scrambling vines of Parthenocissus quinquefolia are common and herbaceous species are very sparse. Umbilicaria mammulata is the most prominent lichen on the boulder surfaces.
