SEP 13 X85 MINED LAND RECLAMATION DIVISION EXHTRTT .7 Vegetation Information* The vegetation on the permit area and adjacent lands has been classified as a Mounta Outwash range site. Potential vegetation on this site consists of approximately thirty percent cover dominated by blue grama, Indian ricegrass, western wheatgrass, needle and thread, winterfat, and fourwing saltbush. Existing vegetation is not indicative of the s potential. Successive years of over grazing have caused ecological deterioration and the: invasion of less desirable species such as rabbitbrush, russianthistle, and pricklypear. At present, the vegetation on the site consists of approximately twenty-five (25) percent cover, generally less than three (3) feet in height, made up of the following grasses, fo. and shrubs: Grasses Blue grama Sand dropseed Western wheatgrass Needle and thread Indian ricegrass Bottlebrush squirrelta.il Fendlers threeawn Tunble grass Shrubs Tall rabbitbrush Threadleaf green rabbitbrush Forbs Blueburr Stickseed Plains pricklypear Pinnate tansymustard Bractless stickleaf mentzelia Tuffed evening primrose Scarlet globemallow Pony beebalm Buckwheat Phlox Russianthistle Vegetation on the site is generally uniform with no significant variations due to soils or topography. The major limiting factor for plant growth on the site is water. Total annual hay production ranges from 300 to 800 pounds per acre air dry with an av- erage of approximately 600 pounds per acre air dry. Existing carrying capacity is ap- proximately one (1) cow/calf unit for every forty-eight (AB) acres grazed annually. * Vegetation information compiled in consultation with the Soil Conservation Service, Center Soil Conservation District.
