• x IPs = average reference area all hit herbaceous cover - improved pasture- subirrigated <br />Average vegetation cover will be used for reclaimed areas because successional development will have <br />established a predominantly herbaceous community even with shrubs present. <br />Revegetation success for cover in the reclaimed portions of the haul road corridor will be <br />demonstrated by comparing the all hit herbaceous cover in the haul road corridor reference area to <br />the all hit total vegetation cover of the reclaimed lands within the haul road corridor. The vegetation <br />cover in the reclaimed area haul road corridor will be considered successful if it is not less than 90 <br />percent of the cover standard with 90 percent statistical confidence. <br />The formula to be used for the haul road cover evaluation is: <br />where: <br />xrevc '90 (XIIRCJ <br />xrevc = average all hit total vegetation cover for revegetated areas <br />XIIRCc = average all hit total herbaceous cover for the haul road <br />corridor reference area <br />Cover will not be evaluated for any cropland areas of the reclaimed haul road. This is based on Rule <br />4.15.9, which states that success of reclamation for cropland will be based on production only. <br />Cover will be measured as described in Sampling Parameters and Sampling Methodologies in the <br />Revegetation Monitoring section presented earlier in this tab. Sample adequacy will be met for both <br />reclaimed and reference area sampling where applicable. All sample points will be randomly located. <br />Production. <br />Reclamation success for production in the mine area will be evaluated by comparing herbaceous <br />production in the reclaimed areas to the weighted herbaceous production value determined from the <br />extended reference area. Herbaceous production will be estimated by clipping the current year's <br />above ground herbaceous biomass randomly located 1/2m2 to 1m2 sample plots. Fencing or <br />exclosures will be used to exclude livestock prior to sampling, where necessary. Production will not <br />be evaluated in the shrub and tree establishment sites. These sites are intended primarily as woody <br />plant establishment sites. These areas will be treated to reduce herbaceous competition for increased <br />woody plant survival. <br />RN -03 37 Revised 10/10 <br />
