King Mountain Sand and Gravel Mine Ecological Resources Assessment Page 19 importance to the sage grouse. Along with the terrace sideslopes, this is the most visible portion of the property. Finally, some portion of the gravel deposits in the northwest portion of the Project site could be excluded from the mine area, in order [o further buffer the lek site one-quarter mile to the northwest of the Project site. This would provide additional mitigation above and beyond that requested by CDOW. The result is a conservation easement roughly 200 acres in size, and a mine area 120-140 acres in size. 8.0 INFORMATION SOURCES Adams, Rick A. 2003.
