ABAM dominated forest at edge of Warren Lake. Regen after fire ~65 yrs. ago. Some fire scarred snags remain from the original forest - bark looks like PIPO. The snags are all >32" dbh. Vegetation is fairly uniform around the lake but there are some large open talus areas. Lake is in a steep bowl. No cyanolichens found. A small amt of Alesar was found but nearly all were shrubby or deformed in some way. Bryoira was sparse too but appeared healthy. Many parasitized, blackened, morphologically altered Plagla & Hypogymnia were observed. In general many lichens especially nearest the lake appeared unhealthy. Slope 25%. Aspect 240°. Abundance code: 4. Substrate: TSME bo.
