Alex P. Schatz January 12, 2001 page 2 not consider the concrete lined drainage channel to fall under Corps jurisdiction. However, both the Last Chance Ditch and the seep ditch fall under the jwisdiction of the Corps. The Last Chance Ditch and the seep ditch appeaz to contain all three criteria necessary to fall under Corps jwisdiction. Two ponds aze located within the Lohman property. The fast pond is located in the northeast comer of the south hayfield. The second pond is located in the southeast corner of the lower cow pastwe. Both fall under the jwisdiction of the Corps, as waters of the United States. Jurisdictional Wetlands Regulated jurisdictional wetlands encountered in Colorado include submergent, emergent, wet meadows, sloughs, swface water drainage ditches, bogs, and potholes. Within the Lohman property, potential jwisdictional wetlands were observed within pockets in the south hayfield and the cow pastwe southeast of the Lohman residence. Within the French property, potential jwisdictional wetlands were observed within a triangle at the southwest property boundary. Jwisdictional wetlands continue from this triangle along the ditch that runs north parallel with the road that sepazates the properties. Preble's Meadow Jumping Mouse Habitat The Preble's meadow jumping mouse (Zapus hudsonrus preblei~ is a federally listed threatened species which generally occurs neaz wetlands and water bodies. Currently, the U.S. Fish and Wildlife Service (USFWS) and Corps are requiring habitat assessment and/or live-trapping surveys for all projects in potential Preble's habitat. The property was evaluated for potential Preble's habitat, based on the current USFWS guidelines. No potential Preble's habitat was found within the properties. Ute Ladies-tresses Orchid Habitat The Ute ladies-tresses orchid (Spiranthes di/uvralis) is a federally listed threatened plant species characteristically found in wet meadows and alluvial flood plains below 6500 feet in northern Colorado, southwestern Wyoming, and the Uintah Basin of Uta1L Habitat assessments and/or pedestrian surveys during the blooming period are required for sites within the South Platte River 100 yeaz floodplain and in characteristic habitat which includes azeas with a seasonally high water table, wet meadows, stream channels, floodplains, azeas with vegetation in the facultative wet or obligate classification, and jwisdictional wetlands. Potential critical orchid habitat was identified within the potential jwisdictional wetlands located at the Lohman property within the south hayfield and the cow pastwe located southeast of the Lohman residence.
