His original field data for these stands, as well as examination of pre-1977 aerial photographs and the fire-killed forest (fig. 2) indicate that much of the prebum forest was composed of dense, stagnating, pole-sized Douglas-fir (Pseudotsuga men- ziesii). Western larch (Larix occidentalis), ponderosa pine (Pinus ponderosa), and above 4,600 feet (1 402 m), lodgepole pine {Pinus contorta) were also present. The north slopes of Pattee Canyon have been roaded and subjected to selective logging thoughout the 1890-1960 period on both Federal and private lands (fig. 1). Th
