• addition to the mechanical or hand planting of seedlings in concentrated areas described later. The <br />shrub seedurg sites will receive approximately 0.5 feet of topsoil and will be deep ripped to a depth of <br />1.5 feet. Seed Mix No. 5 (Table 22-'1) lists the shrub species considered for seeding in these azeas. All <br />spedes aze native to the mine pemtit azea. The seed will be broadcast on a roughened seedbed <br />prepazed by disking. Disking will be conduMed to suppress volunteer species present in the replaced <br />topsoil If the soils aze not excessively rocky, the site may be harrowed to aid in lightly covering the <br />seed. If harrowing is not possible, seeding of these sites should be delayed as late in the seeding <br />season as practical This will allow the anticipated snow cover and freezing and thawing to aid in <br />covering the broadcast seed Drill seeding will be considered as an optional seeding method when <br />applying this mix. The shrub seeding azeas will not be seeded with the permanent mix. <br />The shrub seeded areas will generally be located on north aspects ox azeas which may receive run-on <br />moisture such as depressions or swales. The small relative size and scattering of the sites will reduce <br />erosion potential in these areas of Iow herbaceous cover. On a per acre basis, this method of <br />establishing shrubs is estimated to be as much as eight times less expensive than the planting of <br />seedlings; however, its effectiveness can be variable, If monitoring indicates a greater level of success <br />in seeded versus planted azeas, the seeding of concentrated shrub areas will become the prefeaed <br />• shrub establishment method on remauvng upland sites after CDMG consultation and approval. <br />TABLE 22-7 <br />Seed Mix No. 5 -Concentrated Shrub Seeding Areas <br />Species <br />Seeding Rate` <br />P.L.S. <br />lbs/Acre Seeds/Ft2 <br />Amelancluer alnifolia Saskatoon serviceberry 6.00 6.0 <br /> or <br />Amelanchier utahensis Utah serviceberry .6.00 6.0 <br />eri 'dium vasevanum Mt big sagebrush 0.25 10.0 <br />Padus ~niana melanocaroa Chokecherry 7.00 0.8 <br />Svmnhoricargos rotundifolius Mt. snowbeay 5.00 8.5 <br />Purshia tridentate Antelope bitterbrush 3_00 3.1 <br /> TOTAL 21.25 26.4 <br /> <br />PR-02 17 Revised 10/05 <br />
