�e <br /> modification; the value for "t" should be for a one tailed <br /> distribution, and the value for "d" should be specified to be . 1 . <br /> Note that formula parameters were listed on page 194, but the <br /> formula itself was not included. Appropriate sample adequacy <br /> formulas for reclaimed area sampling are set forth in the <br /> Division's recent bond release guideline, and it is suggested that <br /> the approaches listed in the guideline be incorporated in the <br /> application, along with the reference area sample adequacy formula. <br /> Reference to maximum sample size for production and woody plant <br /> density sampling on page 195 should be deleted; sample adequacy <br /> must be obtained for demonstrations of revegetation success. <br /> c) There should be no need for separate line intercept <br /> transects for woody plant cover and herbaceous cover as indicated <br /> on page 194. <br /> d) On page 195 and 195a, it is stated that species diversity <br /> will be based on relative cover or production for herbaceous <br /> vegetation, and relative density for shrubs. However on page 195b <br /> a separate standard specific to each of three identified vegetation <br /> communities is presented, and each of the three standards <br /> incorporates a relative cover based diversity standard for shrubs. <br /> The references to relative density based diversity standards for <br /> shrubs should be deleted, or the proposed standards should be <br /> modified as appropriate. <br /> e) The proposed standards for species diversity specific to <br /> each of the three identified vegetation communities would be <br /> somewhat cumbersome to apply in practice, and would necessitate <br /> separate bond release evaluation for adjacent reclaimed parcels <br /> which might otherwise be treated as a single unit. The following <br /> diversity standard which would be applicable to all reclaimed areas <br /> is suggested for consideration: <br /> 1 shrub species <br /> 1 perennial forb species <br /> 1 cool season perennial grass <br /> 1 warm season perennial grass <br /> To be counted towards the diversity standard, a species shall <br /> provide at least 38 relative cover, and no single species shall <br /> represent more than 40t relative cover. <br /> f) For similar reasons, a simplified woody plant density <br /> standard applicable to all reclaimed areas is suggested. A <br /> standard of 800 stems per acre would be acceptable to the Division. <br /> 5. As has been discussed during inspections over the past year, <br /> the 1991 revegetation effort at the regraded North Decline Area was <br /> not successful , and remedial measures will be required. A remedial <br /> revegetation plan for this area will need to be submitted by no <br /> later than September 25. 1995, to allow for approval and <br /> implementation during the fall seeding season. The plan will need <br />
