E-12 <br />• Although seeding can occur on the site nearly any time between <br />snowmelt and ground freezing, the optimum time for seeding is <br />during the fall. Accordingly, the seed mixture will be seeded <br />between the time tt~e first killing frost occurs--usually sometime <br />in September--and when the ground freezes--usually sometime in <br />November. The scheduling of revegetation in this manner will <br />allow the seeds to germinate and become established early in the <br />spring when soil moisture is optimum. However, it may be <br />necessary to seed at other times in some instances to either <br />establish a ground cover to prevent soil erosion or to re-seed an <br />area in the event of failed seedling establishment. In these <br />events, seeding may occur during the spring (April-May). <br />• The seed mixture will be placed by either a drill seeder or by <br />broadcast seeding. The use of a drill seeder necessitates <br />having slopes less than 3:1 (33 percent). Drill rows will be 20 <br />to 25 centimeters apart. If the seed is broadcast, the amount of <br />seed indicated will be doubled. <br />Following seeding, :straw or native pasture hay will be applied as <br />a mulch at a rate of approximately 2 tons per acres. If <br />hydromulch is used, rate will be 3/4 - 1 ton/acre. Straw or hay <br />mulch will be mechanically crimped, using a straight running disc <br />on l0-inch centers. Normally, irrigation will not be required to <br />establish a good stand of vegetation, provided that seeding <br />occurs at appropriate timing. Any prohibited noxious weeds that <br />L J <br />
