Groups 1 and 4 are in T1N R67W, and Groups 2, 3, <br />and 5 are in TIN R66W, alt located in the Fon Lupton Quad. <br />Traps were set each evening between 4 PM and 6 PM and opened between 6:00 AM <br />and 8:00 AM the following morning. The weather during the trapping survey was mostly <br />light rain with scattered thunderstorms. Temperatures were cool with highs around 60°F <br />and lows around 40°F. The traps used were Sherman large folding and non-folding <br />aluminum and steel traps with galvanized treadles and doors. Traps were baited with <br />Omelene. <br />Ecological Features of the Site <br />The South Platte River and associated riparian corridor flow along the eastern border <br />of the study area from south to north. Levels of the river were high throughout the <br />trapping survey. A mixture of wetlands, riparian forests, and barren sandbars occur along <br />the river. Wetland areas occur in low-flow backwater areas and areas along the main <br />channel with slow flowing water. Vegetation in wetland areas along the river varies. <br />Dominant vegetation consists mostly of understory species such as prairie cordgrass <br />(Spartina pectinata), reed canarygrass (Phalaris orundinacea), poison hemlock (Corium <br />maculatum), and cattail (Typha latifolio). Small patches of soft-stem bulrush (Scirpus <br />tabernaemontani), lady's thumb (Polygonum persicaria), and blue vervain (Verbena <br />hastate) occur in backwater areas. Sandbar willow (Salix exigua) is the dominant shrub <br />layer in wetland areas along the river. Riparian areas are dominated by plains <br />cottonwood (Populus deltoides), peach-leaf willow (Salix amygdoloides), Russian olive <br />(Elaeagnus angustifolia), and sandbar willow. Understory vegetation consists primarily <br />of smooth brome (Bromus inermis), Canada thistle (Cirsium arvense), showy milkweed, <br />poison hemlock, and poison ivy (Toxicodendron rydbergii).
