f •4 O <br />MC CLANE CANYON •~ <br />Stipulation N9: Requires combined productivity and combined cover (combined <br />within communities, between sites) data from the Munger and McClane vegetation <br />surveys to be used as revegetation success criteria. No work is required To <br />satlsFy this stipulation. Salt Creek Mining will submit a written statement <br />agreeing to this stipulation. <br />Response: Need written response from Salt Creek Mining Company. <br />Stipulation #10: Requires the submittal of woody plant density data for Grease- <br />wood, Shadscale, and Juniper communities. During discussions WRD demonstrated <br />that this information was present in the permit document in Tables 4.5-25 and <br />4.5-28. MLRD will evaluate the data to determine if it meets the requirements <br />of the stipulation. <br />Response: As stated, MLRD will complete this evaluation. <br />Stipulation N11: Justification for proposed woody plant density level success <br />criteria. MLRD is requesting a justification for the levels proposed. <br />Optimally, this justification will include citations from pertinent literature: <br />WRD will provide this discussion. <br />Response: See response to Munger Canyon Mine Stipulation #12. ,' <br />By way of review, the minimum woody plant density standards proposed far <br />the McClane Canyon Mine are as follows: Greasewood Shrubland, 340 stems <br />per acre; Shadscale Shrubland, 300 stems per acre; and Pinyon-Juniper <br />Woodland, 2000 stems per acre. Note that between seeding and transplant- <br />ing, the actual number of woody plants developing may be much higher than <br />the minimum standards. Also note that the maximum direct effort li.e., <br />transplants) is being directed to Pinyon-Juniper Woodland where the <br />greatest value of woody species exists for the greatest number of wildlife <br />species. <br />Stipulation #12: Method/means for evaluation of species diversity on reclaimed <br />areas. MLRD and WRD discussed current thinking on acceptable evaluation methods <br />for diversity. WRD will submit a discussion addressing this topic. <br />Response: Presented in the attached table are lists, by vegetation type, <br />of species occurring in the respective affected areas that exceed 3 percent <br />of the total vegetation cover. It is suggested that these numbers of <br />species by life-form be used as the minimum standards for diversity in the <br />post-mining revegetated areas at the McClane Canyon Mine. The species mixes <br />and shrub transplants specified in the reclamation plan are directed toward <br />establishment of an even greater diversity than that of these standards. <br />Yet, because of the history of grazing abuse in the area, the number of <br />species and life-forms indicated are felt to represent reasonably well the <br />level of diversity in the existing vegetation. <br />-fJ- <br /> <br />
