Abstract: [Study of 18 sites along an altitudinal transect. Lichen communities responded to rock cover, grazing, vascular plants, grazing and timing of snowmelt. "We hypothesize that domestic sheep have dispersed fragments of two lichen species [Xanthoparmelia chlorochroa and Aspicilia hispida] from western Wyoming to grazed sites along the study transect."]
