<br />0(1'549 <br />" Whooping crane (Grus americana), American peregrine falcon (Falco peregrinus), <br />least tern (Stama antiserum), piping plover (Charadrius me/odus), and black-footed <br />ferret (Mustala nigripes). <br /> <br />Several other species are proposed as candidates for listing as threatened or <br />endangered species including the swift fox (Vulpes ve/ox), mountain plover <br />(Charadrius montanus), Arkansas darter (Etheostoma cragim), and Colorado butterfly <br />plant (Guara neomexicana spp. coloradensis). Most of the above threatened, <br />endangered, or proposed species are also on Colorado's state list of threatened or <br />endangered species or are a species of special concern. <br /> <br />The watershed project is not expected to have adverse impacts on any of these <br />threatened, endangered, proposed, or special concern species. <br /> <br />Numerous popular game species are found in the area including: scaled quail, <br />pronghorn, white-tailed and mule deer, cottontail and jackrabbits, ring-necked pheasant, <br />a variety of waterfowl species, and numerouS fish species. <br /> <br />Non-game species are widely represented in the watershed with a variety of shorebirds, <br />songbirds, mammals, reptiles, amphibians, and fish adding diversity to the wildlife in the <br />area. <br /> <br />Wetlands <br /> <br />Many wetlands in the watershed area are located along ditches, drains, and the <br />Arkansas River bottom. These wetlands are primarily PFO (Palustrine Forested), <br />R40W (Riverine, Intermittent, Open Water), R20W (the Arkansas River (Cowardin, <br />1979) and PEM (Palustrin emergent). Irrigated fields also contain a small acreage of <br />wetlands caused by seeps and inefficient water management practices. These wetlands <br />are generally PEM (Palustrine Emergent). The project may result in loss or reduction in <br />size of irrigation induced wetlands in irrigated fields. Estimated average of wetlands in <br />the watershed are: <br /> <br />Type 1,11,111 <br />Type V, VI <br /> <br />3,000 Acres (PEM) <br />12,000 Acres (POW, PFO, R20W, R40W) <br /> <br />Wetlands were digitized using GRASS version 4.2. Data from the 1975 NWI (National <br />Wetland Inventory, USFWS) and NRCS wetland inventory maps from 1990 were <br />transferred to 7.5 minute quadrangle maps for digitization. The actual acres estimated <br />to be affected were adjusted to account for project participation. There will be no net <br />losses of wetland functions due to project action. Mitigation actions will compensate for <br />wetland losses (see alternative "Effects' sections). <br /> <br />Archaeoloav and Historic <br /> <br />Much of the region is in private land and has not been open for study. Cultural remains <br />have been observed and indicate that the area was utilized from the Holocene, The <br />most intensive period of prehistoric use was the Plains Woodland and Early Plains <br /> <br />14 <br />
