• Determination of Revegetation Success. In order to effectively evaluate vegetative <br />reestablishment and ultimate revegetation success, EFCI will monitor revegetated areas at <br />intervals of three (3), seven (7), nine (9) and ten (10) years after initial vegetative <br />reesstabiishment. Collection of vegetation monitoring data will involve the use of similaz <br />methods to those utilized in the collection of vegetative baseline data as described in Section <br />2.04.10, Vegetation Information. Vegetation monitoring will focus on collection and <br />quantification of data for the pazameters of herbaceous plant cover, total herbaceous <br />production, species diversity, and shrub density. Necessary data to assess these parameters <br />will be collected during each monitoring period on both revegetated and reference areas. <br />The purpose of vegetation monitoring efforts during yeazs three (3) and seven (7) on the <br />bond liability period will be evaluation of revegetation trends. Resulting data will be utilized <br />as appropriate to identify any potential areas of concern so that adjustments can be made in <br />post-reclamation management plans to achieve desired revegetation objectives. Revegetation <br />monitoring data collected during yeazs nine (9) and ten (10) on the bond liability period will <br />provide a comparison between reclaimed and reference areas in order to establish and <br />document revegetation success. <br />While the line-intercept method was utilized to collect vegetative baseline information for the <br />Southfield Mine, EFCI will utilize the more efficient point-intercept method to determine <br />vegetative cover. Vegetative diversity will be evaluated using cover data and will determine <br />woody plant density using a weighted average summation of transplant clump density and <br />seeded area woody plant density (detertined by belt transect). Cover sampling will involve <br />establishment of random, 50 meter transects and use of a standard 10-point frame. Woody <br />plant density (seeded areas) will be determined using 50 x 1 meter belt transects along the <br />cover sampling lines. <br />Original baseline vegetative cover data reflects measurement of basal vegetative cover <br />because extensive grazing had significantly altered natural vegetative growth patterns. Both <br />reference and reclaimed areas have not been disturbed by grazing during the interim period <br />and will be subject to essentially the same post-reclamation management program during the <br />bond liability period. Therefore, post-reclamation monitoring will <br />• <br />TR-34 2.05.4-26 Revised 8/02 <br />
