• Species Diversity Using the CMLRD-recommended method, the reclamation success standard for species diversity in the dryland pasture will be establishment of 2 cool season grasses, 1 warm season grass, and 1 perennial forbs. In addition, each of these species must have a relative cover value between 3 percent and 60 percent. Seed mixes for the dryland pasture are provided in Table 11. The rangeland/wildlife habitat will have the same diversity standard as the dryland pasture. Seed mixes for the rangeland/wildlife habitat are provided in Table 12. For the irrigated pasture, the reclamation standard will be establishment of 3 cool season grasses and 1 perennial forb. Again, each species must have a relative cover value between 3 percent and 40 percent. The seed mix for the irrigated pasture is provided in Table 13. The mix was determined using sampling data collected in the irrigated pasture area. Vegetation Cover The vegetative cover standard will be the same for all of the reclaimed vegetation types. However, it will be calculated using the applicable reference area. The vegetative cover standard for a reclaimed area will be 90 percent of the reference area as sampled at the time of revegetation success analysis (see Table 10). Production • The production standard will also be the same for all of the reclaimed vegetation types. Again, the standard will be determined using the reference areas. Production will be 90 percent of the reference area at the time of revegetation success analysis (see Table 10). Shrub Density As shown on Table 10, there is no shrub standard for the three vegetation types. The shrub standard of 333 stems/acre which existed for the rangeland/wildlife habitat type was eliminated through approval by the Colorado Division of Wildlife. Habitat enhancement of other areas in the National Forest will be conducted as an alternative to attempting to establish shrubs on the reclaimed areas. Noxious Weed Control A noxious weed control program has been implemented at the Chimney Rock Mine. This program will include an annual inspection during early summer, and if infestations are observed, a spraying program will be conducted. Recommended spraying with 1.5 pints Banve] and 3 quarts 24-D per acre, when Canada Thistle is in full bolt to 25 percent bloom should control the infestation. Other sprays will be utilized as appropriate for other noxious species. An annual report of the survey and actions taken will be submitted. • 2.05-9
