Roger Peak





Plate 382X. Roger Peak 1948 - 1953 - 2003 The Roger Peak Photo Plot Transect was established in 1943 and reread in 1948, 1953, 1974, and 1979. The transect is situated along the Hell’s Backbone Road on the southside of Boulder Mountain. By road, the transect is located three miles east of Pine Creek and three-tenths of a mile west of the old gravel pit turn-off. When the transect was established, the area was very heavily grazed by domestic sheep and erosion was common. “Bitterbrush and oakbrush are the [most] common shrubs [on] the transect. Both have been heavily browsed and about 20 percent of the [bitterbrush] and 10 percent of the oak is dead. There are a few patches of tall oakbrush…but the majority…[is] 2-3 feet tall and [is] kept browsed off. Grass is not plentiful on this transect.” Both soil and vegetation trends were described as downward in 1953. After remeasuring the transect in 1974, Dan Baird noted that “the most striking change has been the increase in size and numbers of ponderosa pine.” In 1979, Dr. Jim Bowns, range ecologist at Southern Utah University, reported that “the trend…is definitely up and the condition is good or perhaps even excellent…This is primarily a bitterbrush range, the plant exhibiting exceptional leader growth and therefore good vigor…cattle have [used] this area this year, but utilization has been very light” - - domestic sheep use was discontinued sometime in the 1960s (unpublished reports in the range files on the Escalante Ranger District, Dixie National Forest, Escalante, UT). Plate 382x is viewed northeast along the transect centerline back towards the transect starting point - - see Plate 381x. Despite logging and thinning, ponderosa pine has increased dramatically. Bitterbrush is the most common shrub and it has declined where it has been overtopped by conifers. The juniper seen in the initial images were removed when the site was thinned during the 1980s. Grasses appear to have increased in the remaining open areas. Livestock had not used the area in 2003 nor was there any old livestock sign. Deer and elk sign, however, was abundant and many bitterbrush plants were browsed.
