• optional method to be used for establishment of shrub islands or groupings. This will be used in addition to <br />the mechanical or hand planting of seedlings in concentrated areas. Seed Mix No. 5 (Table 13-5) lists the <br />shrub speces to be considered for seeding these areas. All species are native to the site. The seed will be <br />• <br />broadcast on a roughened seedbed prepared by disking. If the soils are not excessively rocky, the site may <br />be hartowed to aid in lightly covering the seed. If harrowing is not possible, seeding of these sites should be <br />delayed as late in the seeding season as practical. This will allow the anticipated snow cover and freezing <br />and thawing to aid in covering the broadcast seed in areas which cannot be hartowed. Drill seeding will be <br />considered as an optional seeding method when applying this mix. The shrub seeding areas will not be <br />seeded with the pemlanent mix. Disking will be considered for suppressing volunteering species present on <br />the replaced topsoil. Reducing herbaceous competition in these areas will enhance the potential for shrub <br />establishment and survival. When used, seeded areas will be approximately one to two acres in size and <br />will be located on north aspects or areas which may receive run-on moisture such as depressions or swales. <br />The small relative size and scattering of the sites will reduce erosion potential in these areas of low <br />herbaceous cover. On a per acre basis, this method of establishing shrubs is estimated to be as much as <br />eight times less expensive than the planting of seedlings; however, its effectiveness has been variable. If <br />monitoring indicates a greater level of success in seeded versus planted areas, the seeding of concentrated <br />shrub areas will become the preferred shrub establishment method on remaining upland sites after CDMG <br />consultation and approval. <br />TABLE 135 <br />SEED MIX NO.5 -CONCENTRATED SHRUB SEEDING AREAS <br />Seeding Rate <br />P.L.S. <br />Ibs/Acre Seeds/FL2 <br /> <br />Amelanchier alnifolia Saskatoon serviceberry 4.00 4.0 <br />Amelanchier utahensis °f Utah serviceberry °r 4.00 4.0 <br />Artemisia tridentate vasevana Mt. big sagebrush 0.25 10.0 <br />Prunus virainiana Chokecherry 5.00 0,6 <br />Svmohodcaroos oreoohilus Mt. snowberry 4.00 6,8 <br />Purshia tridentate Antelope bitterbrush 2.00 0_7 <br /> TOTAL 15.25 22.1 <br />TR-37 1317 Revised 1kU05 <br />
