Pryor Knoll




Plate 1307X. Pryor Knoll 1942 – 2006 Viewed northwest to Pryor Knoll (9,820 ft) on Cedar Mountain. Letterman needlegrass has increased in the foreground and is less heavily grazed than in the past. Aspen has not successfully regenerated in many years due to excessive ungulate herbivory (Ohms 2003). The private rangelands on Cedar Mountain are grazed primarily by sheep. After attending a conference in Cedar City on the decline of aspen in the West, the landowner fenced the aspen clone nearest the camera on the left to exclude domestic sheep and was pleased to see the proliferation of new, unbrowsed suckers, which will eventually become saplings if the fence is maintained.
