Determination of Revegetation Success. In order to effectively evaluate vegetative reestablishment <br />and ultimate revegetation success, EFCI will monitor revegetated areas at intervals of three (3), seven <br />(7), nine (9), and ten (10) years after initial vegetative reestablishment. Collection of vegetatio^ <br />monitoring data will involve the use of similar methods to those utilized in the collection of vegetative <br />baseline data as described in Sec[ion 2.04.10, Vegetation Information. Vegetation monitoring will <br />focus on collection and quantification of data for the parameters of herbaceous plant cover, total <br />herbaceous production, species diversity, and shrub density. Necessary data to assess these <br />parameters will be collected during each monitoring period on both revegetated and reference areas. <br />The purpose of vegetation monitoring efforts during years three (3) and seven (7) on the bond liability <br />period will be evaluation of revegetation trends. Resulting data will be utihzed as appropriate to <br />identify any potential areas of concern so that adjustments can be made in post-reclamation <br />management plans to achieve desired revegetation objectives. Revegetation monitoring data collected <br />during years nine (9) and ten (10) on the bond liability period will provide a comparison between <br />reclaimed and reference areas in order to establish and document revegetation success. <br />While the line-intercept method was utilized to collect vegetattve baseline information for the <br />Southfield Mine, EFCI will utilize the more efficient point-intercept method to determine vegetative <br />cover. Vegetative diversity will be evaluated using cover data and will determine woody plain density <br />using a weighted average summation of transplant clump density and seeded area woody plant density <br />(determined by belt transect). Cover sampling will involve es[abhshment of random, 50 meter <br />transects and use of a standard 10-poin[ frame. Woody plant density (seeded areas) will be <br />determined using 50 x 1 meter belt transects along the cover sampling lines. For the Corley Property, <br />wood}' plants will not be considered in the diversi[}' evaluation and woody plant density will not be <br />evaluated. <br />Original baseline vegetative cover data reflects measurement of basal vegetative cover because <br />extensive grazing had significantly altered natural vegetative growth patterns. Both reference and <br />reclaimed areas have not been disturbed b}' grazing during the interim period and will be subject to <br />essentiall}' the same post-reclamation management program during the bond liability period. <br />Therefore, post-reclamation monitoring will <br />MR-48 2.05.4-26 Revised March 2003 <br />
