Edna Mine Vegetation Final Bond Release Monitoring 2005-2006 <br />WEST RIDGE: TOPSOILED <br />The West Ridge topsoiled area will have weighted averages determined for <br />herbaceous 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 herbaceous cover and production <br />values for their respective reference areas and set the vegetation parameter <br />bond release 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 />combined relative importance standard is waived and does not require <br />evaluation. No other diversity standards applicable to these areas require <br />quantitative vegetation measurement. <br />WEST RIDGE/MOFFAT: PREVIOUSLY DISTURBED <br />West Ridge Previously Disturbed lands include the following parcels <br />• West Ridge outside of the topsoiled areas; <br />• Middle Moffat Haulroad outside of the Out-of-Pit spoil area; <br />• Reclaimed diversion ditch located south of the out-of-pit spoil area; and <br />Habitat Management, Inc. 3 4/8/2025 <br />
