Cogswall 1949 Journal 120 Red Mtns., 5300 ft., 14 mi. S Mayfork, Trinity Co., Lab. Sep. 9 (cont.) - 2. (white fir forest) - in draws on northerly slopes or other moist, protected slopes. Dominants: Abies concolor, with considerably less of Pseudotsuga douglasii and Libocedrus decurrens, Pinus jeffreyi, Pinus lambertiana. The canopy tends to be more nearly closed than the last. In several areas, apparently nearly virgin, the canopy was completely closed except for openings where old trees had fallen. Understory, chiefly Symphoricarpos albus with some Rosa, ocasionally Brumus emarginata, Ceanothus cordulatus. There are large areas of down logs & twig litter in a few upper canyons. 6 of the 7 springs located were surrounded by this association. A few Salix regeliana and Salix sp as well as small green herbs occur around some of those springs, but their extent is insufficient to provide habitat for any riparian type vertebrates. 3. (Manzanita-Ceanothus shrubland) - on the S faces and over the tops of the moderately exposed ridges. Varying in aspect from a nearly solid growth (''chaparral'') to a sparse open formation of very low shrubs. The latter could perhaps be designated a separate association; but there are usually some taller shrubs near enough that
