• 4.4.3 REVEGETATION <br />The materials, methods and techniques to be utilized, and the <br />operations to be conducted in order to revegetate disturbed lands are <br />described in this subsection. Included are species selection, seed <br />mixtures, planting and mulching. Fertility testing and application of soil <br />amendments are discussed under 9.3.5.1 and are not reiterated in this <br />subsection. The specific materials and operations to be conducted on the <br />various types of soil reconstruction materials are discussed individually <br />below. <br />d.4.3.1 Species Selection and Seed Mixtures <br />This subheading includes information concerning the selection of <br />plant species for revegetation of disturbed lands. Included are <br />descriptions of the processes to be used to formulate the permanent, <br />temporary, and interseeding seed mixtures, select species for <br />transplanting, and a mechanism for compiling the seed mixtures used in <br />revegetation operations during the life of the permit. <br />• SPECIES SELECTION <br />A large number of plant species occurring in the Rocky Mountain <br />region have been evaluated with regard to their use in revegetating <br />disturbed lands by a team of reclamation/revegetation experts assembled by <br />the Plant Information Network (P.I.N.) under the auspices of the United <br />States Department of Agriculture's Western Energy Land Use Team <br />(W.E.L.U.T.). A number of the plants contained in this listing have proven <br />themselves in past revegetation efforts at the Edna Mine. Plant species <br />were selected from the P.I.N. listing for revegetation purposes at the <br />Edna Mine based on their ability to enable the revegetation program to <br />realize the goals of establishing a healthy, productive rangeland. <br />The primary considerations used in selecting revegetation species <br />were soil stabilization and adaptability to the mine site (i.e., naturally <br />occurring range including geographic and elevational distribution). <br />Secondary consideration for species selection included cover and food <br />values for wildlife, forage palatability for cattle and sheep, short-term <br />and long-term revegetation potentials, allelopathic attributes (i.e., <br />potential to hinder revegetation by inhibiting growth of other plants) and <br />• faunal toxicity potential. A listing of the plant species selected using <br />these criteria is contained in Table 4.4-1. Seed mixtures and seedling <br />Renewal-3 9.9-7 June 13, 1997 <br />
