Section 4.15.8 will be applicable to these are <br />West p area was Wevinnsly considered a pre -law area which would <br />be, required to meet a cover standard only. However, the area has exp°rienced sumc <br />disturbance fmm the current mining activities. With th exception to the -rand <br />r eclaimed <br />Surface Distarbance/Post Mining Land Use, this arcu <br />established for the East Portal area. The majority of the area will he reclaimed to meet be RvIs <br />Golden roe Grassland Reforcnoc Area standards. However, some small <br />reclaimed to meet wildl3£o habitat (riparian and upland) criteria. Hies e areas llll be regraded <br />and reclaimed as appropriate for the area, including the planting be <br />traversing a wildlife habitat area. However, since these are "pre -la u ]aimed when the <br />met will be based on cover wiLL be Considered C den FAgle Reference Area <br />vegetation cover is equal ter thau 90 p <br />Cover, measured at the time of comparison. <br />Revegetation success of the wildlife riparian habitat which is wnsilercd <br />active disturbance will be based on section 4.15.8 of the regulations. Inactive areas will be <br />evaluated based on cover only. Specific success criteria parameters will be establish lication. <br />sampling of the riparian habitat z discussed <br />in the vegetation section sed referen a area for <br />This data cau be found in the 1987 data shown in F..xhihit 1 S. The plWo <br />riparian habitat is shown on Map 10, Vegetation. <br />Species diversity and visual cover estimates of interim TwIduLatiou activities <br />which occur prior to final reclamation will be moniwced in the third growing se ason <br />following seeding. This sampling will not achieve statistical adequacy. Evaluation of <br />revegeladuu efforts shall begin following the f initial seeding of a reclamation <br />year o <br />management unit_ Evaluation of seeded areas shall occur in Year 4 and two years prior to <br />final bond release. The results of the revegetation success evaluation will be submitted to ft <br />Division with the Annual Reclamation Report for the Year. <br />Vegetative cover and diversity will be sampled using, 25mctcr long- intercept transects. The <br />reclaimed area and reference aura will be sampled separately- Sampling transcet locations for <br />both reclaimed areas and reference areas will be provided on the <br />vegetation map <br />Ten ttanseets will initially be conducted in each area Sample size will be <br />determined as sufficient using the SnedecorCochran sample adequacy formula (equation 1), <br />or when 50 transects have been sampled. <br />TR-48 <br />2.05 -51 (Revised 3/3/06) <br />
