n U A Greasewood Shrubland vegetation type occurs on the flat terrain of the exploration area. The major soil type in this vegetation type is the Glendive sandy loam, a deep, well- drained, medium textured soil. The Havre loam, a deep, well-drained, medium-fine textured soil is also common. This latter soil is very sodic and moderately saline, characteristics ofren associated with greasewood vegetation types. This Greasewood Shrubland is a climax vegetation type. Plant species common to Greasewood Shrubland vegetation type include; trees, shrubs and subshrubs, graminoids, forbs, and succulents. Ants are a major factor in the ecology of this Greasewood Shrubland vegetation type, affecting vegetation and soil cover. Large circular shaped bare spots, 3 to 10 meters in diameter and stripped of vegetation by ants occur with symmetric spacing throughout the vegetation type. The Big Sagebrush Shrubland vegetation type occurs in deep loamy soils of drainages. Big Sagebrush occurs mainly on the Rivra Nihililoam. Plant species common to Big Sagebrush Shrubland vegetation type include; shrubs and subshrubs, graminoids, forbs, and succulents. Shadscale Shrubland occurs on extremely dry, steep, south-facing slopes bordering the Greasewood Shrubland. This vegetation type is in the torriorthent rock outcrop complex of soils, which is a heterogeneous mixture of shallow to deep soils interspersed with rock outcrops. Shad scale appears to be the climatic climax for these habitat conditions. Plant species common to Shadscale Shrubland vegetation type include; shrubs and subshrubs, graminoids, forbs, and succulents. • Juniper Woodland occurs on the steep, north and west facing slopes and ridge tops surrounding the exploration area. This vegetation type occurs mainly on the torriorthent rock outcrop complex although inclusions of Havre loam, a deep, well-drained soil. Juniper Woodland is the climatic climax for these environmental conditions. Plant species comrnon to Juniper Woodland vegetation type include; trees; shrubs and subshrubs, graminoids, forbs, and succulents. The Mountain Shrubland Vegetation type occurs mainly on north-facing slopes. The density of the shrubs vanes with the degree of the slopes. Shrub densities increase on the very steep slopes and tend to occur as patches and small clumps on the gentler slopes. The dominance of individual shrubs is most variable. Neazly pure stands of mountain mahogany occur in some sites while in other habitats, Utah serviceberry donunates. Gambel oak increases in importance at higher elevations. Soils Soil types in the proposed exploration area aze categorized by the Soil Conservation Service, U.S. Department of Agriculture, on the Douglas Plateau Area and consists of the Cameo, Badland, Battlement Loam, Hesperus, Torriorthents, Torrifluvents, Tosca Channery Loam and Wrayha-Rabbitex-Veatch Complex. The Cameo Series, 1 to 6 percent slopes, This deep, well-drained soil is on flood plains and low terraces. The native vegetation is mainly very spazse low desert shrubs and grasses. It formed in stratified alluvium derived from mixed material. The surface layer is fine sandy loam about 4 inches thick. The underlying material to a depth of 60 inches is stratified sandy loam 4
