Show 4 displacement of soil particles could be expected on recently disturbed sites during high intensity storms, but because of the proposed location of the improvements displaced material should not enter the Duchesne River. Vegetation The dominant vegetation on the proposed development site is sagebrush and bitterbrush·with some willow species and cottonwood along the Big Springs Canal above the development, and conifer, willow, and cottonwood species below the proposed site adjacent to the Duchesne River. l'here is an understory of grasses and forbs, including some introduced species. This site has been used as a horse pasture for many years. Vegetation disturbance will remove about 2 acres 0: the brush type from production; Some of this will be temporary during development, but in the long term about l~ acres will be permanently removed by the work area and access roads. Revegetation of temporary disturbed .sites, such as the ftrainfi~ld, well drilling area, and temporary access roads, will reduce the impact on vegetation. No known threatened or endangered species of plants are present on the area. Wildlife and Fish No live streams will be affected by the development if ~ork is done to a proper standard to prevent any silt movement into the Duchesne River. The site is ·located on a big game winter range inhabited primarily by mule deer. The fenced yard will be lost to deer use. It will involve about 1 acre of land as there will be a high chain link fence to prevent deer from entering the work area. Some small mammal species will be displaced through the disturbance and development of the yard and roads. There are no known threatened and endangered species of wildlife present. Fire The equipment operation and work activity at the site will increase the risk of a fire starting. Hazards should be reduced through landscaping, species conversion, and fuelbreaks as a result of road development. The new water storage facility proposed with this administrative site should. improve the fire storage and capability of preventing wildfire starting from existing and proposed structures on the mountain lands. |
