Edna Mine Vegetation Final Bond Release Monitoring 2005-2006 <br />Vegetation cover is the only final bond release parameter that must be satisfied <br />by the West Ridge: Previously Disturbed area and Moffat: Previously Disturbed <br />Area. The vegetation cover standard for these areas is 47% based on <br />monitoring conducted prior to redisturbance by mining. <br />Voluntary diversity goal for West Ridge and Moffat previously disturbed lands is <br />graminoids 90%, (orbs 5% and trees/shrubs 5%. The final vegetation bond <br />release monitoring report will include an evaluation of life form distribution. <br />NOTE: This plant life form distribution is a voluntary goal and failure to meet it <br />will not prevent final vegetation bond release. <br />MOFFAT AREA: TOPSOILED <br />Moffat Area reclamation that received topsoil will have weighted averages <br />determined for cover and production liability release standards. Premining plant <br />community mapping and the actual disturbance area will be used to determine <br />the weighting factors. This will be accomplished by determining the acreage <br />within the disturbed area that was in either snowberry sage or oak/mountain <br />shrub vegetation community types. Percentages values will be calculated using <br />the acres of disturbance within these two vegetation communities. These <br />percentages will be used to weight the average cover and production values for <br />their respective reference areas and set the vegetation parameter bond release <br />standard. <br />Recommended standards for diversity of herbaceous, woody plants and overall <br />revegetation community have been established and will be used to describe <br />dominance, species numbers and utility. Herbaceous Species Diversity requires <br />the presence of at least five perennial herbaceous species with each relative <br />importance of each species equal to or greater than 3% and less than 40%. <br />Combined relative importance of the 5 species will not exceed 75%. If 6 or more <br />species have relative importance that lies within this range, then the maximum <br />Habitat Management, Inc. 4 4/8/2005 <br />
