Iron Spring Draw

1961

2003

Description:

Plate 340X. Iron Spring Draw 1961 - 2003 The Iron Spring Draw Photo Plot Transect on Escalante Mountain was established in 1943 and reread in 1948, 1953, 1961, and 1979. The transect is 1250 feet in length and runs across Iron Spring Draw just above the Sink Holes. When this transect was established, range conditions were exceedingly poor and soil erosion was widespread. “The area sampled by this transect is some of the most badly eroded range I have seen in a long time. The slope on the west side of [Iron Spring] Draw is cut by numerous active gullies, sheet erosion is severe, [and] Festuca ovina is pedestaled one inch to over six inches…Along the bottom the area that was once a good meadow is gutted by a wash 20 to 30 feet and more wide and four to six feet deep…The picture is one of severe depletion of the range resource. Channel banks are mostly vertical with chunks of soil breaking off into the creek…licken lines are to be found more prominent than I have ever noticed any where in Region 4. The lines can be found from about two inches to as much as 18 inches above present soil levels”. Conditions had not improved much by 1979 as Dr. Jim Bowns, range ecologist at Southern Utah University, noted that “this is one of the poorest areas that we have examined on the Aquarius Plateau. There are areas of severe erosion and active gullies….Hummocking of Festuca ovina is very prominent in this area. This condition, however, appears to be from hummocking as a result of cryopedogenic processes rather than strictly erosion caused by grazing….Condition is probably no better than fair. Trend has been slightly up since the transect was established, but is basically stable now. This is an extremely harsh site…” (unpublished narrative reports in the range files on the Escalante Ranger District, Dixie National Forest, Escalante, UT). Plate 340x is viewed southwest back to the Photo Plot Transect starting point - - see Plate 332x. This photopoint, however, is north of the transect centerline. The original image was taken to document the fresh soil eroded from the hillside. Judging by the large boulder in the lower right corner of the photographs, soil erosion has slowed considerably from what it was in 1961. Silver sage has increased. The area was actively being grazed by cattle in 2003, but use was not as heavy as it was on sites closer to the creek.
