0 <br />• <br />REVEGETATION PLAN <br />The approved revegetation plan emphasizes native species planting resulting in a <br />diverse, permanent, effective plant community capable of self -regeneration. <br />Species and Planting Methods <br />Plant species proposed for use in revegetation were selected considering local <br />environmental features of soils, nutritional value, slope, elevation, and <br />precipitation, as well as the vegetational potential of the site. The current seed mix <br />is entirely composed of native species. Warm season graminoid species <br />predominate in the mix, as they do in the native area adjacent to the mine. CDMG, <br />CDOW and the SCS have all agreed that sand sage (Arlemesia frlifolia) need not <br />be included in the seed mix.

In small areas requiring reseeding, CEC may employ broadcast <br />seeding methods to stimulate regrowth. Broadcast seeding rates will be twice that <br />of drill seed rates. <br />Germination of native warm season grasses has proven to be problematic in <br />reclamation. ,The preeminent factor in successful germination of warm season <br />native grasses appears to be available moisture.
