Only about 30% of plot is covered by trees. At least 10% of area is barren (dispersed patches throughout). Plants very homogenous. Well developed understory of PUTR and RICE with little else. About 95% of tree cover is PIPO. A few renmant old-growth PIPO occur outside plot. Almost all potential lichen substrates are extremely exposed. Lichen community homogenous. Almost every mature PIPO and PICO holds hundreds of minor thalli on lowermost branches (Cetmer, Letvul, Letcol, Vulcan, small crusts). No single thallus on plot has reached a size greater than a quarter! Canopy appears to be even more depauperate...it looks BARE. Slope 5%. Aspect 76°. Abundance code: 4-1. Substrate: PICO cone.
