June 6, 2012 C-1981-016/Hawk Nest E & W JRS <br /> <br /> <br />RECLAMATION SUCCESS (cont.): - Production data was based on the dry weight of all live grasses and forbs <br />(2012 growth only) clipped from either a 0.25 or 0.5 square meter quadrat that was placed to the right of each <br /> <br />degrees for approximately 1 week. Samples were then weighed on an analytical balance and a pounds/acre <br />production amount was calculated. <br />- Based on the sampling, the east mine had a live vegetative cover value of 24.3% and a hydrologic cover value of <br />79.4% (hydrologic cover includes live cover, litter and rocks). The east mine had an average productivity rate of <br />586 pounds/acre. The three dominant species at the east mine were western wheatgrass, intermediate wheatgrass <br />and slender wheatgrass, with relative cover percentages of 10.6%, 3.1% and 2.9%, respectively. The percentage <br />of relative cover from noxious weeds at the east mine was 2.0%. The cover at the east mine was sufficient to <br />stabilize the surface and no erosional problems were noted. <br />- Based on the sampling, the west mine had a live vegetative cover value of 28.1% and a hydrologic cover value of <br />85.6% (hydrologic cover includes live cover, litter and rocks). The west mine had an average productivity rate of <br />519 pounds/acre. The three dominant species at the west mine were crested wheatgrass, yellow sweet clover and <br />western wheatgrass, with relative cover percentages of 16.0%, 5.3% and 5.1%, respectively. The percentage of <br />relative cover from noxious weeds at the west mine was 2.8%. The cover at the west mine was sufficient to <br />stabilize the surface and no erosional problems were noted. <br />- Based on the sampling, the bleeder entry area had a live vegetative cover value of 24.0% and a hydrologic cover <br />value of 79.5% (hydrologic cover includes live cover, litter and rocks). The bleeder entry area had an average <br />productivity rate of 192 pounds/acre. The three dominant species at the bleeder entry area were smooth brome, <br />western wheatgrass and intermediate wheatgrass, with relative cover percentages of 17.5%, 2.0% and 2.0%, <br />respectively. The percentage of relative cover from noxious weeds at the bleeder entry area was 3.0%. The cover <br />at the bleeder entries area was sufficient to stabilize the surface and no erosional problems were noted. <br />- Ba <br />had an average productivity rate of 528 pound <br />crested wheatgrass, western wheatgrass and yellow sweet clover, with relative cover percentages of 7.9%, 7.4% <br />and 2.7%, respectively.
