• oats to be planted will vary according to those varieties available in a <br />given year. The oat seed will germinate rapidly to form an effective <br />temporary cover as well as a natural mulch for later permanent seeding <br />operations. The cover crop seed will be utilized on di=_turbed areas when it <br />is determina_d that planting the permanent seed mixture is less beneficial due <br />to the specific season and/or poor growing renditions due to extended <br />drought. <br />The proposed seed mixtures include a number of introduced speci?s which have <br />been included in the seed mixtures due to their proven effectiveness in <br />establishing and adapting under conditions similar to those at the Southfield <br />site. Introduced species included in the seed mixtures include the following: <br />o Intermediate wheatgrass <br />o Crested wheatgrass <br />o Cicer milkvetch <br />All of the introduced species have been utilized extensively and have proven <br />their value in revegetation of disturbed areas in the west. The noted grass <br />. species have been included in the seed mixtures due to their ease of <br />establishment, rapid growth, soil holding capabilities and forage value. <br />Cicer milkvetch was added to the reclamation seed mixture at the Division's <br />request. Inclusion of Cicer milkvetch in the seed mixture is based upon its <br />known nitrogen fixing capabilities, longevity, and palatability as a browse <br />specie. <br />In order to ensure that seed materials are of suitable quality. EFCI will <br />attempt to obtain these materials from sources most closely approximating <br />site conditions, and will deal only with reputable established seed <br />suppliers. Prior to seeding, seeding specifications will be reviewed to <br />ensure that all seed meets acceptable standards for purity and guaranteed <br />germination rates. <br />Seeding Methods EFCI will generally use one of two seeding methods <br />dependent upon the nature and aspect of the area to be reclaimed. Drill <br />seeding with a conventional rangeland seed drill will be utilized for most <br />reclamation work. Drill seeding rates, in PAS/acre, are shown for the <br />individual seed mixtures on Tables 33 and 33a. To the extent possible. EFCI <br />will drill seed along the contour in order to establish linear contour line <br />• features which help break-up sheet runoff and minimize the potential for rill <br />and gully erosion. <br />2.05.3-22 Revised 5/28/02 <br />Minor Revision No. 45 <br />
