Table 1 Environmental and physical characteristics of study sites. The PIPO group is the ponderosa pine group, and the ABGR group is the grand fir group. ELGL = Elymus glaucus Buckley; CARU = Calamagrostis rubescens Buckley; CAGE2 = Carex geyeri Boott; and LIBO3 = Linnaea borealis L. PAG is plant association group, which describes the relative temperature and moisture regime of sites (Powell et al. 2007). ABGR 1890 % refers to grand fir as a proportion of total reconstructed basal area in the year 1890. Sites ranged in size from 4 ha to 12 ha. Variables were calculated as the average of values for 15 systematically located plots in each site.
