Arboreal lichens of the Engelmann Spruce - Subalpine Fir (ESSF) zone (Coupe, 1982) are the main source of mid to late winter forage for caribou within the drainages of the North Thompson River (Edwards et al. 1960). Clearcutting of stands within the ESSF zone completely removes the supply of lichen for a period of time. Preserving these stands from logging would cause a reduction in the annual allowable cut for the forest industry. It has been suggested that selective or partial cut logging might provide adequate lichen forage for caribou while maintaining sufficient timber supply. The impact of selective cutting on arboreal lichen cover and abundance is poorly documented for this area. Therefore, studies of lichen standing crop in selectively cut and mature forest stands are necessary.
