Bar b67 <br />Craig. CO 81625 <br />~- _.DYBL.Mr..._COOpYLL~• <br />As discussed with Marvin Moose. we have no objection to the Road Department <br />trying to use a more standardized seed mixture in lieu of the many different <br />miaturee required in your current permits. Since we have developed a <br />reclamation performance standard, we no longer require or formally recommend <br />specific seed miztures. Therefore, we will waive use of the seed mixtures <br />required in all active permits ae long ae revegetation meets the following <br />performance standard. <br />ReveAetation Standard <br />Reclamation will ensure growth of a diverse, self-regenerating, permanent <br />vegetative cover of the same seasonal growth ea adjoining vegetation. <br />Diversity will be accomplished if at least two (2) perennial genera and three <br />(3) perennial epeciea make up the basal cover of the reclaimed area in <br />precipitation zones thirteen (13) inches ar less and three (3) perennial <br />genera and four (4) perennial species in precipitation zones greater than <br />thirteen (13) inches. One epeciea will not make up more than fifty (50) <br />percent of the perennial vegetation by basal cover. <br />Self-regenerating vegetation will be evident if the plant community ie in good <br />vigor and there is evidence of successful reproduction. <br />Permanent vegetative cover will be accomplished if the basal cover of <br />perennial species is at least ninety (90) percent of the basal cover of the <br />undisturbed vegetation of adjoining land or the potential basal cover as <br />defined in the Soil Conservation Service Rsage Sites (s) for the area. <br />This waiver and application of this standard should give you flexibility to <br />use a more standardized seed mixture based on availability, coat and site <br />factose. <br />
