Description:

Plate 331X. Coyote Hollow 1943 - 1948 - 1953 - 2003 The Coyote Hollow Photo Plot Transect on the Aquarius Plateau was established in 1943 and reread in 1948, 1953, and 1979. The transect is 2400 feet in length and is located approximately 400 yards below Coyote Hollow Reservoir. Five of the eight plots on this transect sample a silver sage meadow, while the remaining three plots sample the aspen-spruce type. When this transect was established, the range was in poor condition and soil erosion was widespread. “Between 1943 and 1948 sheep use was eliminated” on this allotment. Nevertheless, in 1953 I.H. Johsnon noted that “the evidence of deterioration of the forage resource over shadows the minor indication of some improvement…in weighing all the factors, the evidence points most strongly to the conclusion that the vegetation trend is downward…[In addition] there are no indications that soil loss is being stopped in any noticeable degree.” By 1979, however, conditions had improved for according to Dr. Jim Bowns, range ecologist at Southern Utah University, “there is presently little indication of soil movement. Condition is difficult to assess due to the low productive potential. I would judge this range to be in fair condition. Trend has been upward since the transect was established.” Dr. Bowns added that the pedestaled grass plants were the result of “frost hummocking rather than strictly soil movement due to overgrazing” (unpublished reports in the range files on the Escalante Ranger District, Dixie National Forest, Escalante, UT). Plate 331x is viewed northeast back to the transect starting point on the rocky ridge above Coyote Hollow. Both the person and the truck in the 1943 image are on the transect centerline. The entire area is dotted with mima mounds - - slightly-elevated circular landforms created by pocket gophers over hundreds or thousands of years. Sheep fescue is the most common grass while the most common shrub is silver sage, which is especially thick on top of mima mounds where soils are deeper. Despite the severe drought that has gripped southern Utah for several years, range conditions appear to have improved and there is no evidence of recent soil erosion. In the distance, conifers have increased, while aspen has declined. All aspen suckers showed evidence of repeated browsing. Silver sage appears to have declined. The area was actively being grazed in 2003 - - note the herd of cattle in the 2003 retake (center right edge). Elk use was also evident.
