• is included as an optional method to be used for establishment of shrub islands or <br />groupings. This will be used in addition to the mechanical or hand planting of Seedlings <br />in concentrated areas. Seed Mix No. 5 (Table 13-5) Lists the shrub species to be <br />considered for seeding these areas. All species are native to the site. The seed will be <br />broadcast on a roughenetl seedbed prepared by disking. If the soils are not exc essiveLy <br />rocky, the site may be harrowed to aid in lightly covering the seed. If harrowing is not <br />possible, seeding of these sites should be delayed as late in the seeding season as <br />practical. This will allow the anticipated snow cover and freezing and thawing to aid in <br />covering the broadcast seed in areas which cannot be harrowed. Drill seeding will be <br />considered as an optional seeding method when applying this mix. The shrub seeding areas <br />will not be seeded with the permanent mix. Disking will be considered for suppressing <br />volunteering species present on the replaced topsoil, Reducing herbaceous compel iCion in <br />these areas will enhance the potential for shrub establishment and survival. when used, <br />seeded areas will be approximately one to two acres in size and will be located on north <br />aspects or areas which may receive run-on moisture such as depressions or swales. The <br />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 shrubs is <br />• estimated to be as much as eight times less expensive than the planting of seedlings; <br />however, i[s effectivensss has been variable. If monitoring indicates a greater level of <br />success in seeded versus planted areas, the seeding of concentrated shrub areas will <br />become the preferred shrub es tabtishment method on remaining upland sites after DMG <br />consultation and approval. <br />TABLE 13-5 <br />Seed Mix Ro. 5 - Concentrated Shrub Seeding Areas <br /> • <br /> Seeding Ra[e <br /> P.L.S. <br /> 2 <br />___ Seecies_ __ lbs[ACre_ _Seeds[Ft._ <br />Amelanchier elnifolia Saskatoon se rviceberry 4,00 4.0 <br />Amel anchier utahens is or Utah serviceberry or 4.00 4.0 <br />Artemisia [ridentata vasevana M[. big sagebrush 0.25 10.0 <br />Prunus virainiana Chokecherry 5.00 0.6 <br />$YIIIDh oricarpos oreophilus Mt. snowber ry 4.00 6.8 <br />Purshia tridentata Antelope bitterbrush 2.00 0_7 <br /> TOTAL 15.25 22.1 <br />13-21 Revised 01/15/93 <br />
