Observation Narrative	Plot located in forested swamp just north of the most upstream beaver meadow 40 m west of main channel of Catharpin Creek in Jackson Hollow, 0.6 mi ESE of White Rock Spring and 0.8 mi ENE of Signal Mountain summit. Not permanently marked. Rock types present: quartzite boulders. An absolutely beautiful example of forested seepage swamp vegetation, unfortunately highly threatened by the potential expansion of beaver clearings and meadows located just downstream. Toxicodendron vernix is impressively large and abundant here. This community's floristic composition features several more or less montane disjuncts (Glyceria melicaria, Isoetes valida, Veratrum viride, Maianthemum canadense, Anemone quinquefolia, Mitella diphylla) along with species more typical of low elevations in Virginia (Toxicodendron vernix, Woodwardia areolata, Carex seorsa). Water pH and temperature data collected 2005-03-09. Mean groundwater pH (5 samples) = 5.03. Mean groundwater temperature (deg. C, 5 samples) = 6.22.
