I • <br /> <br /> <br />include shale derived soils that are fine textured and have a potential for saline/alkaline <br />soil conditions. Net soil conditions are also likely to be encountered in Dry Creek or <br />areas of poor drainage. The mix contains species that are adapted to these varying site <br />characteristics and are able to provide long-term stability. Tall statured species such as <br />basin wildrye and fourwing sa Ltbush will provide structural diversity. Eleven out of the <br />twelve species are natives with the majority native to the region. The composition of the <br />mix wilt ensure a return of productivity and utility (eve is necessary to meet the postmining <br />land uses. <br />Seed Mix ~NO. 4 (Table 20-4) is a temporary stabilization mix to be used for temporary <br />reclamation of temporary disturbances in place more than one year. Temporary disturbances <br />in place less than a year will be seeded to a cover of barley or winter wheat. <br />The four seed mixes contain the following introduced species: <br />Intermediate wheatgrass <br />Russian wildrye <br />Alfalfa <br />Redtop <br />Neadow brome <br />Orchardgrass <br />Timothy <br />these species are desirable and necessary to achieve the postmining land uses and are <br />compatible with plant end animal species of the region. The species are well documented in <br />a variety of technical literature and have proven performance in meeting similar land uses <br />or reclamation goals. The species are not poisonous ar noxious. <br />Shrub end tree plantings are not planned in any reclaimed area. The majority of the <br />reclaimed sites will be reclaimed to the two types of pasture. The remaining native <br />reclaimed areas are smaller in areal extent and are, for the most part, narrow in width. <br />The proximity of adjacent native shrub communities and the limited surface disturbances will <br />allow for reinvasion of shrubs in a relatively short ecological time frame. Fourwing <br />saltbush has been included in the mix to encourage establishment of shrubs in the interim. <br />Seeding Methods. Seeding of the permanent seed mixes will be carried out during the first <br />available planting season after topsoil distribution and seedbed preparation. Spring <br />3 <br /> <br />
