Most of the park is very wet. We sampled in a site on a small hill - soils were stable and dryer with a thick organic layer. Overstory consisted of TSHE mostly and a few ACMA, ALRU, PSME and THPL. TSHE was the dominant species varying in age from sapling to old growth ~dbh 47. Some very large trees on this site 100-200 years. Thick shrub layer of BENE and RUUR forbs included mostly ferns, tons of POMU. Site seems to be healthy, very little human use since people stay on the trail NE of the plot. Parmelia sulcata was very abundant and Hypent, Hypphy and Hypmet were found. A few species of Usnea. Overall lichens were sparse and were smaller in size. Signs of a fire on old stumps and snags were seen. Slope 45%. Aspect 58°. Abundance code: 2. Substrate: PSME litter.
