Elevation ranges from 2,073 meters (6,800 <br />feet) to 2,560 meters (8,400 feet) within the area of intensive investigation, <br />but extends up to approximately 3,353 meters (11,000 feet) to the south in the <br />flat tops. Precipitation in the area averages 41 cm (16 inches) annually. <br />Temperature is subject to large seasonal and daily variations. In Jury, tem- <br />peratures range from an average high of 27oC (S1oF) to an average low of 6.7oC <br />(44oF). January temperatures range from O.OoC (32oF) to -17oC (1.4oF), re- <br />spectively. <br />Five major vegetation types occur in or adjacent to the permit area: <br />aspen, mountain shrub, sagebrush, grassland and cultivated land. The aspen <br />type is found in the highest areas of best soil moisture conditions predomi- <br />nantly on northerly facing slopes. Grasses make up approximately 15% of the <br />understory, major species being bromes (Bromus marginatus), bluegrasses (Poa <br />spp.), and sedges (Carex spp.). Forbs make up about 50%, major species being <br />nettleleaf giant-hyssop (Agastache urticifolia), western yarrow (Achillea <br />lanulosa), pea vine (Lathyrus sp.), meadowrue (Thalictrum sp.), and violet <br />(Viola spp.). Shrubs make up about 35%, major species being snowberry <br />(Symphoricarpos occidentalis), chokecherry (Prunus virginiana) and service- <br />berry (Amelanchier alnifolia). <br />The mountain shrub type is found on the steeper south facing slopes and <br />lower north facing slopes. Grasses make up about 15%, major species being <br />sedges, bromes, and wheat grasses (Agropyron spp.). Forbs make another approx- <br />imately 15%, major species being nettleleaf giant-hysop, western yarrow, and <br />pea vetch (Vicia sp.). Finally, shrubs make up about 70%, major species being <br />gambel oak ( uercus gambelii), snowberry, chokecherry and serviceberry. <br />The sagebrush type occurs mostly at elevations below the mountain shrub <br />' type but small patches are scattered among other habitat types. Grasses make <br />up about 15%, major species being bromes, bluegrasses, wheat grasses, and Idaho <br />' fescue (Festuca idahoensis). Forbs make up about 35%, major species being <br />mulesear (W ey thia amplexicaulis), lupine (Lu inus sp.), pea vetch and western <br />' yarrow. Shrubs make up about 50%, major species being sagebrush (Artemisia <br />tridentata), snowberry, and bitterbrush (Purshia tridentata). <br />1 <br />-3- <br />1 <br />
