This section is divided into the following subsections: 4.4.1 <br />OVERVIEW, 9.9.2 BOND RELEASE SUCCESS STANDARDS, 9.9.3 REVEGETATION, <br />9.4.9 MONITORING, and 9.9.5 STUDIES. <br />4.4.2 BOND RELEASE SUCCESS STANDARDS <br />This subsection contains a description of the success standards for <br />revegetation that permanently reclaimed lands will be required to meet for <br />Phase III release of reclamation performance bonds. Success standards for <br />Topsoiled Rangeland, Substitute Soil Rangeland and Riparian reclaimed plant <br />communities are described by category below. Also, the methods to be used <br />to measure the parameters of cover, diversity, productivity and woody stem <br />stocking are presented. The following provides a listing of the various <br />areas and the reclamation success standards/criteria applicable to each <br />area. <br />1. West Ridge: <br /> a. Topsoiled areas in Sections 19 and 23, T9N, R86W, under <br /> permanent program revegetation success criteria - Cover, <br /> production and diversity based on reference area <br /> comparisons. <br /> b. Previously disturbed areas using substitute soil <br /> reconstruction material lincluding opportunistically <br /> salvaged topsoil material in Section 13 and 29, T4N, <br /> R86W) - cover standard of 978 (based on pre-redisturbance <br /> cover value) <br />2. Moffat area: Cover, production, diversity, and woody stem <br /> density based on reference comparisons, except for woody stems. <br /> The woody stem density standard is 1000 stems per acre. <br />3. Facilities areas: Cover standard of 47~ (based on West Ridge <br /> pre-redisturbance cover value). <br />9. Center Ridge: Cover standard of 928 (based on previous bond <br /> release approval for remainder o£ Center Ridge). <br />Renewal-3 <br />4.4-1 June 13, 1997 <br />
