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 sagebrush <br />rangeland on the 1987 Travessitta - Pinon soils and on 1999 soil map units 9813, 98C, and 98H <br />(see Map 2.04.9 -1). It also will be established on former irrigated lands that do not have sufficient <br />water for future irrigation. Although attempted in the past, irrigation will not be employed on <br />dryland pasture. <br />Some dryland pastures will be restored such that, if water becomes available in the future, these <br />lands could be irrigated after the liability period. <br />Seed Mix #8 is specifically designed for has been developed for dryland pasture on this permit <br />area, to provide a mix of species that are compatible with the dryland pasture type, have a high <br />level of utility, and will provide long term protection of the resource. <br />Some areas will be reclaimed to dryland pasture where water is not sufficient for irrigation. Other <br />areas reclaimed to the dryland pasture type occupy locations where the Pinon- Progresso loams <br />complex (1987), soil map units 98C, 9813, and 98H (1999), and sagebrush vegetation types <br />occurred prior to mining (see Section 2.04.9 and 2.04.10). Some of these reclaimed areas will <br />have only received ancillary disturbances during mining activities. The associated disturbance <br />relates to topsoil removal for the location of roads, stockpiles, facilities, and regrading activities <br />during reclamation. These areas were not flood irrigated prior to mining because of shallow soils, <br />rock outcrops, and topography. Since these areas will remain basically unchanged in terms of <br />topography, they will not be irrigated in the postmine land use. The establishment of a dryland <br />pasture type is consistent with both the pre- and postmining land uses in the area and best reflects <br />that which is attainable under the expected site conditions and management potential. <br />Any dryland pasture reclamation will involve drill seeding of a sterile hybrid annual triticale <br />( Quickguard) in combination with Seed Mix #8. Quickguard will be planted either in the fall <br />preceding a summer perennial planting or in the spring preceding a fall dormant seeding of the <br />PR -06 June 2010 2.05.4(2)(e) - 52 <br />
