COLORADO 81625 <br />In Reply Refer To: <br />3600 (170) <br />August 5. 1991 <br />Mr. Warren Cooper <br />Moffat County Aoad Department <br />P.O. Baz 667 <br />Craig, CO 81625 <br />. Deaa.Mr.._Coopars_._..._. <br />Ae discussed with Marvin Moore, we have no objection to the Road Department <br />trying to use a more standardized seed mixture in lieu of the many different <br />mixtures required in your current permits. Since we have developed a <br />reclamation performance standard, we nc longer require or formally recommend <br />specific seed mixtures. Therefore, we will waive use of the seed mixtures <br />required in all active permits ea long ae revegetation meets the fallowing <br />performance standard. <br />Revegetation Standard <br />Reclamation will ensure growth of a diverse, self-regenerating, permanent <br />vegetative cover of the same seasonal growth as adjoining vegetation. <br />Diversity will be accomplished if at least two (2) perennial genera and three <br />(3) perennial species make up the basal cover of the reclaimed area in <br />precipitation zones thirteen (13) inches or less and three (3) perennial <br />genera and four (4) perennial species in precipitation zones greater than <br />thirteen (13) inches. One species 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 is 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 ae <br />defined in the Soil Conservation Service Range Sitee(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 />factors. <br />
