Obli ate Upland Species: Occur in wetlands in another region, but occur almost always (estimated probability >99 percent) under natural conditions in non-wetlands in the region specified. If a species does not occur in wetlands in any region, it is not on the National List of Wetland Species. (While the U. S. Department of Interior National List includes many species, there are instances when non-wetland species that are not included on the National List can be found in wetland areas.) As part of the field work, all observed species occurring within wetland areas were recorded. Field searches and compilations of the species lists aided in the assessment of the potential status of the occurrence of Ute Ladies Tresses Orchid and potential habitat for this species as well as similar information for Colorado butterfly plant. The field work for this project was conducted between May and September 2004. RESULTS Threatened and Endangered Plant S ecies. Two species of concern could occur within the project area: Ute Ladies Tresses Orchid (Spirantltes diluvialis) and Colorado butterfly plant (Gaurn neomexicann ssp. coloradensis). These species occur in wetland areas in the Front Range region of Colorado. Known populations for the orchid species occur in the Boulder area within the South Boulder Creek drainage. Colorado butterfly plant is known from a location near Ft. Collins. Ute Ladies Tresses Orchid was not observed in any of the wetland areas that that were evaluated as part of this study. In general, the habitats that occur within the Ft. Lupton areas are not appropriate for this species. Some of the species that are known to occur with Ute Ladies Tresses Orchid were observed; however the species that were observed tend to be widespread and occur in many wetland settings where Ute Ladies Tresses Orchid does not occur. Colorado butterfly plant was not observed in any of the wetland areas that were surveyed. Small-flowered gaura (Gnura parviflora) was observed in several different locations; however the two species are easy to distinguish and have very different habitat requirements. It is unlikely that either of these two species occur within the project area. Descriptions of Wetlands. Wetlands identified on each of the project properties are described in the sections that follow. The sections include general descriptions of the sites, maps of the wetland areas, descriptions of the wetlands, lists of species observed in the wetland areas and photographs of the different wetlands. -5-
