systems or water storage for that purpose. The vegetation around these ponds is similar to <br />that found in the swale type and along the irrigation ditches. <br />Soil map units 98A, 98D, 98E, 98F and 98G have a sagebrush -grassland potential native plant <br />community characterized by the Semidesert Loam Range Site. This Range site is described in <br />the 1987 study within this document. <br />Soil Map units 98C, 986, and 98H have a pinyon -juniper woodland potential native plant <br />community characterized by the Pinyon -Juniper Woodland Site Description. This Range site is <br />described in the 1987 study within this document. <br />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 americana). <br />Intermingled and moving away from the bank, are rushes and sedges (typically Carex <br />nebrascensis and Carex occidentalis) along with horsetail (Equisetum kansanum), salt grass <br />(Disticlis stricta) and alkali sacatone (Muhlenbergia asperfolia). In some areas coyote willow <br />(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 loam <br />deposited by major flood events. The terrace is 1 to 5 meters above the stream channel and is <br />dry at the surface but receives subsurface moist from the stream. The alluvial terrace has had <br />varying degrees of human activity. The most intensively managed parts of the alluvial terrace <br />are an irrigated hayland pasture owned by Johnson and irrigated pastures owned by Martin <br />and Lloyd. The majority of the alluvial terrace have had disturbances with the removal of native <br />sagebrush, rubber rabbitbrush, four -wing saltbrush and greasewood. Abandoned areas have <br />been reinvaded with these species along with Russian knapweed, Lappula, burdock, <br />cheatgrass and pricly pear cactus. The remaining native trees are Fremonts cottonwood and <br />longleaf cottonwood. Russian olive has invade along with saltcedar in a few areas. <br />February 2015 (TR -66) 2.04.10-82 <br />
