An example of how the forage quality diversity production sampling data obtained from the <br />sampling of the Dryland Pasture reclaimed areas will be compared to the Dryland Pasture <br />Reference Area can be made based upon the data presented in Section 2.04.10. If bond release <br />sampling were to be performed using these data, the forage quality diversity standard as found in <br />Appendix Table 2.04.10-25 - Dryland Pasture Reference Area - Production, yields an average <br />value of 8.40 g/l/4m2. Ninety percent of this value, which equals the probable revegetation <br />success forage diversity standard, equals 7.56 g/1/4m2. This would mean that the forage <br />production of "desirable species" on the Dryland Pasture reclaimed areas would have to be equal <br />to or greater than 75 percent of 7.56 g/1/4m2 or 5.67 g/l/4m2. <br />As are described in the Weed Management Plan, Montrose or San Miguel County listed noxious <br />weed species will not be counted toward the revegetation success standard for cover or <br />production in any reclaimed area. For the purposes of this demonstration, a statistically adequate <br />production sample will be taken, or a minimum of 30 observations. <br />As are recommended in the Bond Release Guideline, the cover and production contribution of <br />annual and biennial species will be excluded prior to the determination of the total perennial <br />herbaceous forage production. Therefore, as provided for in the CDRMS regulations, all <br />annuals, biennials and listed noxious weeds will be deleted from the reclaimed and reference <br />area data prior to success comparison. Sample adequacy will be tested during field sampling <br />using the formula in DRMS Regulation 4.15.11(2)(a). <br />During bond release field sampling for cover, at least 15 cover transects and 30 production <br />transects will be collected from each sample area. Sample adequacy will be tested after 15 cover <br />and 30 production samples are taken. Sampling may continue if necessary to reach sample <br />adequacy, or sampling may be terminated before sample adequacy is reached if an alternative <br />statistical method (approved by DRMS) can be used that does not require demonstration of <br />sample adequacy. <br />Reclaimed area cover and production will be compared to a standard equal to the mean values <br />measured at the reference area by sampling, as described below. Revegetation will be <br />considered successful if the mean value for the reclaimed site can be demonstrated to equal or <br />exceed Q (Q=90% of the standard). One of the four methods, discussed in Rule 4.15.11(2), will <br />be used to compare mean values at reclaimed sites to Q, depending on the mean values and <br />whether sample adequacy was reached during sampling. In the event that sample adequacy is <br />achieved for both sites, and the sample mean from the reclaimed site exceeds the standard then <br />revegetation success will be determined by direct comparison (Regulation 4.15.11(2)(a)). <br />However, if sample adequacy is not achieved for one or more sites then one of the statistical <br />comparison tests found in Rule 4.15.11(2) will be used to determine the successfulness of the <br />parameter in question. <br />Section 10S.4(2)(e) Page 24 May 2015 <br />
