<br />Quality <br />1. select grasses, fortis and shrubs that •:rill control <br />erosion and reduce sediment. This vegetative cover <br />will reduce runoff, act as a filter to trao_ sediments <br />and sediment attached substances, increase infiltration <br />and reduce loss of :rater soluble ..^.utrients and <br />chemicals into downstream water courses. In most <br />situations agricultural chemicals coill not be used or <br />greatly reduced ~:rhich in turn will bene**i*_ surface and <br />ground crater quality. <br />SPECIFICATIONS <br />A. Species Selection: <br />1. Select grass, 'orb and shrub species that are adapted to <br />the soil and/or range site. Follow the guidelines in the <br />applicable standard and specification such as Range Seeding <br />=550, ?assure and Hayland Planting 8512, .~ildlife Upland <br />Habitat ?4anage^.ent =645 and Critical area Planting ;342. <br />Where available, use the specifications developed at the <br />area office level =or appropriate species selection. <br />2. For seedir,q rates, seedbed preparation, seeding equipment <br />requirments, planting depths, seed quality, erosion control <br />measures, management during establishment, etc., refer to <br />the above listed specifications. <br />B. Management After Establishment: <br />1. To maintain and/or renovate new or existing stands of <br />seeded vegetation, practices such as Proper Grazing Use <br />;528, Pasture and Hayland Management =510, Prescribed <br />Burning ;338, Planned Grazing Systems X556 and mowing or <br />shredding will be needed. Vegetation that consists <br />primarially of introduced cool season grass species may <br />need periodic fertilizaticn to maintain vigorous stands. <br />Soil tests are recommended to determine appropriate <br />fertilizer amounts. <br />2. Mowing and or shredding can be used to maintain grass <br />stands. These practices may be the only options in some <br />situations. Mowing or shredding should be done at a time <br />that ne*d growth will be initiated soon after the mowing or <br />shredding operation is completed. The major purpose is to <br />reduce standing decadent material and put it in contact <br /> <br />TGN #258 {page 2 of 3) SCS Colorado, January 1991 <br />
