4 <br />Wetland Evaluation at the Duckworth Property <br />July 2003 <br />Prepared by: <br />Warren R. Keammerer, Ph.D. <br />Keammerer Ecological Consultants, Inc. <br />5858 Woodbourne Hollow Road <br />Boulder, Colorado 80301 <br />Introduction <br />This report presents the results of a wetland delineation at the Lafarge <br />Duckworth Property site in Weld County, Colorado. The wetland delineation study <br />focused on an area along and in the vicinity of Idaho Creek. hr addition to mapping <br />wetlands, an assessment of the status of Ute Ladies Tresses orchid (Spiranthes diluvialis) <br />and Colorado Butterfly plant (Gaura neomexicana ssp. coloradensis) was conducted. Field <br />work for this project was conducted in late June-July 2002. <br />Methods <br />Wetlands were delineated using a combination of air photo interpretation and <br />field checking. An aerial photo base map at a scale of 1 inch equals 200 feet was used to <br />evaluate the location of wetland areas within the study area. These areas were visited in <br />the field and were evaluated relative to wetland status using the U. S. Army Corps of <br />Engineers (198'7) wetland delineation manual. Boundaries of delineated wetlands were <br />flagged in the field and were subsequently surveyed using standard surveying <br />procedures. Reed (1988) was used as the basis for categorizing the plant species <br />observed in the wetland areas. Ixr cases where species were not listed in Reed (1988), <br />wetland indicator status was assigned on the basis of how the species tend to grow <br />within the region. These assignments were based on the experience of the author of this <br />report. <br />As part of the field work, all observed species occurring within wefland areas <br />were recorded. Field searches and compilations of the species lists aided in the <br />assessment of the potential status of the occurrence of Ute Ladies Tresses Orchid and <br />potential habitat for this species. Part of the field work for this project was conducted in <br />late July (2002) at a time when Ute Ladies Tresses Orchid would have been in flower. <br />Permit#: 3- Confidental?: Wl~ <br />Class: ~ Type-Seq.: <br />From: To: <br />Doc.
