• (e) A diverse, effective, and permanent cover of vegetation of the same <br />seasonal variety native to the area will be established over all disturbed <br />parts of the affected surface areas. <br />(i) Seeding and planting of disturbed areas will be conducted during <br />the first normal period of favorable planting conditions following <br />final preparation for seeding. Seeding will normally be done in the <br />fall from mid October through mid November for drill seeding and <br />through mid December for hydro or broadcast seeding. Spring <br />seeding will be done during March or April. Summer seeding will <br />be done from mid July through August. The seed mix to be used <br />for an area will generally be determined by the elevation of the area <br />to be seeded, see page 14-25. Table 14-8 presents the upland <br />and lowland seed mixes to be used after December 2001. Tables <br />14-4, 14-6 and 14-9 through 14-13 present the seed mixes used <br />prior to December 2001. <br />(ii) Species to be planted and amounts of seed per acre are specified <br />• in Table 14-3 -Temporary Seed Mixture and Table 14-8 - - <br />Permanent Seed Mixes .Winter wheat, oats or barley at a rate of <br />20 - 30 lbs./acre may be used as a temporary cover for dirt work <br />completed between optimum spring and fall seeding periods. <br />(iii) The seed mixture(s) will be drilled on level areas and on slopes <br />which will permit machine work along the contour. On slopes which <br />prevent safe or adequate machine work, the surface will be <br />hydroseeded or broadcast seeded. Broadcast seeding will also be <br />used for small isolated areas. Dozer tracking up and down steep <br />slopes or other roughening techniques will be used before seeding <br />to establish a better seedbed. On predominantly south and west <br />facing steep slopes, the surface will be extensively roughened to <br />provide for increased moisture retention and favorable micro sites <br />for plant establishment. <br />(iv) All seeded areas will be mulched with certified weed free grass hay <br />or straw. Approximately two tons of mulch will be used on each <br />• acre seeded. <br />14-16 (Rev. 6111/04) <br />
