The cultivated land in the <br />project area provides foraging areas for big ganle. waterfowl, and upland game species. <br /> <br />3.10.4.1 Alternative 1 - No Action <br /> <br />The No Action Alternative would have no effect on terrestrial wildlife in the project area. <br /> <br />3.10.4.2 Alternative 2 -Improve Routing of Pawnee Creek Flood Flows (Proposed <br />Action) <br /> <br />With Alternative 2, approximately 45 acres of land would be temporarily disturbed. <br />Approximately 43 of these acres represent wildlife habitat including 33 acres cropland and 10 <br />acres of upland/riparian habitat. Following construction, approximately 28 acres of cropland <br />would be returned to crop production and 5 acres occupied by dikes and levees would be <br />revegetated with native grass species. The disturbed upland/riparian areas would also be <br />reseeded with native grass species. Cropland and upland/riparian habitat is abundant within and <br />adjacent to the project area; therefore, wildlife species could move into surrounding areas during <br />construction. Repopulation of disturbed areas would be rapid after the disturbed areas are <br />revegetated. Temporary disturbance of 33 acres of cropland and 10 acres of upland/riparian <br />vegetation and the conversion of 5 acres of cropland to native grasses would not have a <br />noticeable long-term effect on local wildlife populations in the project area. <br /> <br />3.10.4.3 Alternative 3 - Pawnee Creek Overflow Cutoff <br /> <br />With Alternative 3, approximately 41 acres ofland would be temporarily disturbed. <br />Approximately 39 of these acres represent wildlife habitat including 32 acres cropland and <br />7 acres of upland/riparian habitat. Following construction, approximately 28 acres of cropland <br />would be returned to crop production and 4 acres occupied by dikes and levees would be <br />revegetated with native grass species. The disturbed upland/riparian areas would also be <br />reseeded with native grass species.

None of the alternatives would be expected to have an adverse effect on <br />aquatic resources in Pawnee Creek. <br /> <br />3-18 <br />
