as a shrub conducive reclamation procedure, CDMG may be contacted to initiate alternate reclamation procedures for the remainder of Colowyo reclamation. [As of March, 2008, these test plots had not been constructed because of the impending revision to the reclamation plan. Because of this revision and the reasonable promise of success for the new proposed procedures, construction of these test plots has been placed "on-hold" until as such time as they may become necessary.] As a result of negotiations with CDOW and DRMS regarding approval of TR-72, Colowyo has committed to implementing three field trials in the future as reclamation progresses. 1) Colowyo agrees to establish one small (not greater than 1 acre) aspen establishment area on associated disturbance in an area where the original lithology is still intact. The location and specific plan for this area will be developed on a site specific basis as the opportunity to implement such a trial presents itself. 2) Colowyo agrees to establish one small (not greater than 1 acre) tall shrub establishment site that that displays a thick topsoil condition. The location and specific plan for this area will be developed on a site specific basis as the opportunity to implement such a trial presents itself. 3) Colowyo agrees to establish one small (not greater than 1 acre) tall shrub establishment site with thin topsoil conditions. The location and specific plan for this area will be developed on a site specific basis as the opportunity to implement such a trial presents itself. It is understood that these areas will need to be planned and established prior to the completion of active reclamation activities in the the South Taylor Mining Area. 4.15.7 DETERMINING REVEGETATION SUCCESS: GENERAL REQUIREMENTS AND STANDARDS The following text in this section and the next section (4.15.8) supersedes all previous text on this subject matter. During the summer of 1980, two reference areas were selected to represent the two major vegetative communities to be disturbed, sagebrush and mountain shrub. The locations of these reference areas are shown on the Vegetation map (Map 4) and Regional Vegetation map (Map 3). Extensive, detailed vegetative sampling was performed, duplicating the methodologies as described in Section 2.04.10. The reference areas were sampled for herbaceous cover, herbaceous production and woody plant density. Species diversity was determined utilizing herbaceous cover data from the premining inventory of the sagebrush and mountain shrub communities. The reference areas are each approximately seven acres in size. 4.15-12 Revision Date: 3/14/08 Revision No.: TR-72
