2.04.9 Soils Resource Information substratum is a pinkish -gray loam and clay loam extending to a depth of 60 inches or more. Runoff is moderate and the erosion hazard for water is slight. Wind erosion hazard is moderately severe. The unit is mainly used for rangeland and wildlife habitat. It is also used for pasture. The present plant community is mainly cheat grass, western wheat grass, big sage, and greasewood. Glendive soil is in capability unit 111 a dryland, 11 a irrigated, foothills swale range site 2. Havre soil is in capability unit 111 c dryland, 11 c irrigated, on 0 to 2 percent slopes and 11 a dryland and 11 a irrigated on slopes greater than 2 percent, foothills swale range site Fruita soil is in capability unit V1 e dryland, loamy salt desert range site. MAP UNIT: HMB - HAVRE LOAM, SALINE PHASE, 0 TO 8 PERCENT SLOPES This map unit is on nearly level to gently sloping valley bottoms and flood plains. The slope is 0 to 8 percent. The native vegetation is mainly a greasewood-shru bland community. Included in this map unit is about 10 percent Uffens silt loam, and about 10 percent Glendive loam. Included areas make up about 20 percent of the total acreage. The Uffens soil is a member of the fine -loamy, mixed, mesic family of Typic Natrargids. Areas of Uffens soils less than 1.5 acres each are designated on the map by a saline/sodic spot symbol, 0. Typically, the surface layer of the Havre soil is a light brownish gray or light gray loam about 6 inches thick. The substratum to a depth of 60 inches or more is a saline brown, grayish brown, or light gray stratified loam, silty clay loam, or sandy loam. Permeability of the Havre soil is moderate. Available water capacity is moderate to moderately high. Effective rooting depth is 60 inches. Runoff is slow and the erosion hazard for water is moderate. Wind erosion hazard is slight. The unit is mainly used for rangeland and wildlife habitat. It is also used for pasture. The present plant community is mainly cheat grass and western wheat grass with big sage and greasewood. The potential productivity is 2,500 and 1,200 pounds of air-dry vegetation in favorable and unfavorable years, respectively. This map unit is in the capability unit 111w irrigated on 0 to 2 percent slopes and 1 Vw irrigated on 2 percent and steeper slopes, foothills swale range site3. 2 Range site established in Moffat county. 3 Range site established in Moffat county.
