6.0 Revegetation - Dryland Pasture (DP) <br />6.1 General Information <br />The reclaimed dryland pasture type will be established in areas which were previously <br />sagebrush rangeland on the 1987 Travessitta - Pinon soils and on 1999 soil map units 9813, <br />98C, and 98H (see Map 2.04.9 -1). It also will be established on former irrigated lands that do <br />not have sufficient water for future irrigation. Although attempted in the past, irrigation will not <br />be employed on dryland pasture. <br />Some dryland pastures will be restored so that, if water becomes available in the future, these <br />lands could be irrigated after the liability period. <br />Seed Mix #8 has been developed for dryland pasture on this permit area, to provide a mix of <br />species that are compatible with the dryland pasture type, have a high level of utility, and will <br />provide long term protection of the resource. <br />In cases where pastureland is being reclaimed, but water for irrigation is not present, the land <br />will be reclaimed as dryland pasture. Other areas reclaimed to the dryland pasture type occupy <br />locations where the Pinon- Progresso loams complex (1987), soil map units 98C, 9813, and 98H <br />(1999), and sagebrush vegetation types occurred prior to mining (see Section 2.04.9 and <br />2.04.10). Some of these reclaimed areas will have only received ancillary disturbances during <br />mining activities. The associated disturbance relates to topsoil removal for the location of <br />roads, stockpiles, facilities, and regrading activities during reclamation. These areas were not <br />flood irrigated prior to mining because of shallow soils, rock outcrops, and topography. Since <br />these areas will remain basically unchanged in terms of topography, they will not be irrigated in <br />the postmine land use. The establishment of a dryland pasture type is consistent with both the <br />pre- and postmining land uses in the area and best reflects that which is attainable under the <br />expected site conditions and management potential. <br />Any dryland pasture reclamation will involve drill seeding of a sterile hybrid annual triticale <br />(Quickguard) as a companion crop within Seed Mix #8. Seed mix #8 is the permanent seed mix <br />for the dryland pasture. Seeding of dryland pasture will take place during either of the two time <br />frames: 1) between July 15 and September 15, or 2) between October 25 and April 15 in the <br />August 2013 PR -08 2.05.4(2)(e) - 53 <br />
