• Canada thistle was found in the Sagebrush and Improved Pasture Affected areas This <br />• species likewise has occurred in the Seneca II Mined and Reclaimed Land and it has been <br />the target of weed control efforts. <br />Livestock Carrying Capacity <br />Livestock carrying capacities for cattle based on study production data from 2008 would be <br />estimated as follows. <br />Mountain Brush Affected Area - 0.453 aum /ac <br />Mountain Brush Extended Reference Area - 0.471 aum /ac <br />Sagebrush Affected Area - 0.599 aum /ac <br />Sagebrush Ext.

Area — 0.723 aum /ac <br />Little Grassy Creek - Preliminary Wetland /Riparian Characterization <br />is (Photographs 59 through 66) <br />As part of the Sage Creek Mine baseline study, a preliminary characterization of areas potentially <br />to be affected by surface facilities was conducted. These areas located along the portion of Little <br />Grassy Creek within the Seneca II permit boundary (Map 7) were examined on October 10, 2008. <br />Part of this reach of the drainage lies within a natural channel (Photographs 59 through 61 and 63 <br />through 65) and part lies within mine reclamation in a recreated channel (Photographs 62 and <br />66). The purpose of this preliminary characterization was to generate a rough idea of the extent <br />of obligate hydrophytes that might evidence the presence of wetland conditions and at the same <br />time also assess the extent of adjacent area that though subirrigated likely was not wetland in the <br />formal (U.S. Army Corps of Engineers, USACOE) sense. This effort was reconnaissance in <br />nature and not intended to satisfy USACOE delineation criteria. <br />The area along Little Grassy Creek surveyed extended from north to south along a distance of <br />approximately 1.3 mi. (see Map 7). Another side - drainage extends down across reclamation from <br />the east then runs parallel to Little Grassy Creek before joining it near the north end of the studied <br />reach (Map 7). The vegetation of this side drainage was also included in this reconnaissance. <br />• 34 <br />
