In order to consider all shrub est at~l ishment technologies, concentrated seeding of shrubs <br />is included as an additional method to be used for establishment of shrub islands or <br />patches. This will be used in addition to [he mechanical or hand planting of seedling:. in <br />concentrated areas described later. The shrub seeding sites will receive approximately <br />0.5 feet of topsoil and will be deep ripped to a depth of 1.5 feet. Seed Nix No. 5 (TZ~ble <br />22-7) lists the shrub species considered for seeding in these areas. AIL species are <br />native to the mine permit area. The seed will be broadcast on a roughened seedbed <br />prepared by disking. Disking will be conducted to suppress volunteer species present in <br />the replaced topsoil. If the soils are not excessively rocky, the site may be harrowed to <br />aid in lightly covering the seed. If harrowing is not possible, seeding of these sites <br />should be delayed as late in the seeding season as practical. This will allow the <br />anticipated snow cover and freezing and thawing to aid in covering the broadcast seed. <br />Drill seeding will be considered as an optional seeding method when applying this mix. <br />The shrub seeding areas will not be seeded with the permanent mi.x. The shrub, seeded <br />areas will be approximately one to two acres in size and will generally be located on <br />north aspects or areas which may receive run-on moisture such as depressions or swal es. <br />The small relative size and scattering of the sites will reduce erosion potential in these <br />areas of low herbaceous cover. On a per acre basis, this method of establishing shrub:: is <br />estimated to be as much as eight times less expensive than the planting of seedlings; <br />however, its effettivensss can 6e variable. If monitoring indicates a greater level of <br />success in seeded versus planted areas, the seeding of concentrated shrub areas uill <br />become the preferred shrub establishment method on remaining upland sites after CDMG <br />consultation end approval. <br />SABLE 22-7 <br />Seed Mix No. 5 - Concentrated Shrub Seeding Areas <br />Seeding Rate <br />P.L.S. <br />• <br />• <br /> z~ <br />Species lbs/Acre Seeds/Ft. <br />Amelenthier elnifolie Saskatoon serviceberry 6.00 6.U <br />Amelanchier utahensis or Utah serviceberry or 6.00 6.0 <br />Seri ohidium vasevanum Mt. big sagebrush 0.25 10.0 <br />Padus virwiniana melanocerpa <br />Svmohoricaroos rotundifotius <br />Purshie tridentate <br />Chokecherry <br />Mt. snowberry <br />Antelope bitterbrush <br />TOTAL <br />7.00 0.8 <br />5.00 8.5 <br />3.00 t_1 <br />21.25 26.4 <br />• <br />1B Revised 06!19/95 <br />
