Permit M-1977-493-Climax Mine Technical Revision 37 (TR-37) <br /> ■ All other reclamation areas will be seeded with the upland standard seed mixture (Section E-7.1.2). <br /> A concerted effort will be made to acquire the recommended seed mixture; however, species availability can vary <br /> from year to year. If substituting species is necessary, a list of alternative species has been included for each of <br /> the recommended seed mixtures in this section. The seed mixtures are designed to maintain a diversity of life <br /> forms (e.g., perennial grasses, perennial forbs, and woody plants) should there be a need to revise the seed <br /> mixture with alternative species. <br /> E-7.1.1 Temporary/Stabilization Seed Mixture <br /> The temporary/stabilization seed mixture (Table E-1) may be used in reclamation areas that require temporary <br /> cover or stabilization. This seed mixture may be broadcast or hydroseeded at a target rate of 100 pure live seeds <br /> per square foot (PLS/sf). <br /> Table E-1: Temporary/Stabilization Seed Mixture <br /> Desired <br /> Species Avg.
