The following areas are outside the permit area. <br />6.11 Channel Bank The channel bank is directly adjacent to the Tuttle Draw water surface. It <br />is continually saturated with water and supports a variety of native and introduced hydrophytic <br />graminoids and forbs. Closest to the stream, the bank is lined with scirpus (Scirpus <br />americana). Intermingled and moving away from the bank, are rushes and sedges (typically <br />Carex nebrascensis and Carex occidentalis) along with horsetail (Equisetum kansanum), salt <br />grass (Disticlis stricta) and alkali sacatone (Muhlenbergia asperfolia). In some areas coyote <br />willow (Salix exigua) and saltcedar (Tamarisk sp.) predominate. The channel also has a few <br />cottonwoods (Populus fremontii and Populus longifolia) and Russian olive. Intoduced species <br />have also invaded the channel bank. The species include alfalfa, Russian knapweed, <br />milkweed. Plantain (Plantago lanceolata), Yellow and white honeyclover <br />6.12 Alluvial Terrace The alluvial terrace is comprised of sands, loamy sands and sandy <br />loam deposited by major flood events. The terrace is 1 to 5 meters above the stream channel <br />and is dry at the surface but receives subsurface moist from the stream. The alluvial terrace <br />has had varying degrees of human activity. The most intensively managed parts of the alluvial <br />terrace are an irrigated hayland pasture owned by Johnson and irrigated pastures owned by <br />Martin and Lloyd. The majority of the alluvial terrace have had disturbances with the removal <br />of native sagebrush, rubber rabbitbrush, four -wing saltbrush and greasewood. Abandoned <br />areas have been reinvaded with these species along with Russian knapweed, Lappula, <br />burdock, cheatgrass and pricly pear cactus. The remaining native trees are Fremonts <br />cottonwood and longleaf cottonwood. Russian olive has invade along with saltcedar in a few <br />areas. <br />6.13 Sagebrush Reference Area This reference area was established in the initial permitting <br />of the mine and is to be replaced by the new dryland pasture reference area. In agreement <br />with the CDMG, it was tested in the1999 sampling program. The sagebrush reference area <br />represents remnants of native rangeland that has not been converted to the more <br />characteristic intensive agricultural land uses in the area. The sagebrush reference area is <br />located at SW1 /4, NE1 /4, Sec. 36, T.47N., R.16W. Between the old Peabody Site to the north <br />Revised September 2010 (PR 06) 2.04.10 -83 <br />
