• Bond release requests will contain final revegetation monitoring <br />results which demonstrate that the reclaimed areas meet or exceed release <br />criteria. Final revegetation monitoring will include cover, productivity <br />(annual biomass production) and diversity. Statistical adequacy <br />requirements as specified in the regulations will be met. Ground cover, <br />production and diversity will be compared to their respective standards <br />established in 9.9.2 using appropriate statistical tests as described in <br />2.4. Final revegetation monitoring results will be submitted to the CMLRD <br />with the phase III bond release request for the area. <br />4.6.4.3 Revegetation Monitoring Methods <br />Diversity and cover will be measured using randomly generated ten- <br />point frame transects. Starting locations for transects will be determined <br />by overlaying the permitted area with a numeric grid. Transect direction <br />will also be randomly generated on one of the 16 points of the compass. <br />Transects that meet the edge of the monitoring area will be randomly <br />redirected into the monitoring area. Each data point recorded will specify <br />litter, rock, bare soil, or the individual species of plant. <br />• Productivity (annual biomass production) will be measured by clipping <br />0.25 mz hoop plots that are randomly selected along the 100 meter diversity <br />and cover transects. Only herbaceous species will be considered in <br />productivity clippings. Air-dry or oven-dry weights may be used, with the <br />standard conversion equation used for comparison (Bonham or equivalent <br />(oven-dried weight is 90 percent of air-dried weight)). <br />Woody plant density will be measured using random, 50-meter long, <br />modified-belt transects. The transects will be two meters wide. Each <br />individual woody plant observed within the transects' area will be counted <br />only once (each woody plant with multiple stems will be counted as only one <br />plant). <br />4.6.5 STUDIES <br />This subsection has been included in order to provide a common <br />location where pertinent studies or other monitoring conducted on <br />revegetated areas at the mine may be compiled for historic purposes and <br />future use. Appendix 9.4-B has been set aside for the inclusion of interim <br />revegetation monitoring results. Appendix 9.9-C has been set aside for the <br />• insertion of the results of phase III revegetation bond release monitoring. <br />Appendix 9.9-D contains the study required by the OSMRE which compared <br />Renewal-3 9.4-23 June 13, 1997 <br />
