As the first stage in a program to evaluate the effects of selective logging on caribou (Rangifer tarandus caribou), the biomass of forage lichens (Alectoria sarmentosa and Bryoria spp.) below 6 m on standing trees was quantified in an Engelmann spruce-subalpine fir (Picea engelmanni - Abies lasiocarpa) stand in the Selkirk Mountains of southeastern B.C. Assessment methods were a combination of ratio estimation and variable probability sampling. Total amounts of forage lichen within reach of caribou in the three mature timber plots were estimated at 67±37 kg/ha, 103±21 kg/ha and 105±37 kg/ha. This forage base is relatively low, both in terms of the herd's estimated food requirements and compared with other caribou ranges. Selective logging to a 51 cm diameter at stump height would reduce available lichen to just over one-quarter of its original amount. Within the Selkirk caribou range, selective logging should be restricted to areas used by caribou for travel. Logging of any kind should be prohibited in areas
