. Description and hydrologic analysis of two small watersheds in Utah's Wasatch Mountains. VEGETATION The early history (1847 to 1930) of land use along the Wasatch Front is marked by log- ging, fire, and severe overgrazing. Timber stands were depleted, regeneration was sup- pressed, and meadow and understory grasses and forbs were depleted (fig. 6). Mud-rock floods originated on denuded mountain slopes and meadows during high intensity summer rainstorms. Since its inclusion in the National Forest System in 1933, the DCEW has been completely protected from logging, fire, and grazing by domesti

Since its inclusion in the National Forest System in 1933, the DCEW has been completely protected from logging, fire, and grazing by domestic livestock. In addition, in- tensive watershed restoration practices, in- cluding contour furrowing and reseeding, were applied to flood-source areas which in- cluded the stream bottoms and lower side slopes of both study watersheds of Chicken Creek. The areas that were contour furrowed are generally defined on the soils map (page 52) by soil type 16 and some of the adjacent areas; the furrowed areas comprised about 15 percent of both watersheds. Most of the treated area remains in grass and brush vegeta- tion, but some furrows can be seen in the low-. Figure 6. — An aspen stand that has been logged and heavily grazed. Forage is depleted, aspen regeneration is suppressed, and the exposed soil presents a serious erosion hazard. Photo- graphed during the era of severe land abuse, circa 1930. 10.
