Use Of Netted-Cage Traps In Population Management And Research Of Urban White-Tailed Deer, Kurt C. Vercauteren, Jeff Beringer, Scott Hygnstrom
Great Plains Wildlife Damage Control Workshop Proceedings
Growing populations of white-tailed deer (Odocoileus virginianus) in urban areas often conflict with local human interests and present challenges to natural resource managers. Netted-cage traps can be an important tool for management of urban deer populations where traditional control methods may not be appropriate or acceptable. We discuss the design of netted-cage traps, trapping techniques, and the handling of trapped deer.

Nine types of footsnares were tested on captive coyotes (Canis latrans) at the United States Department of Agriculture Predator Research Facility. Preliminary results indicate that the E-Z Lee, Nelson, Freemont, and Godwin leg snares can be effective in restraining coyotes while causing only minor leg injuries. Additional testing will be required to determine the effectiveness of these devices in different field situations. Four types of coyote leg-hold traps were evaluated to determine the injuries they inflict on captured coyotes. The No. 3 1/2 McBride padded trap caused the least injury in comparison to 3 other trap models that …

Specialized radio transmitters were developed for use in monitoring large mammal trap and snare activity. Prototype devices were manufactured by 4 wildlife telemetry companies based on specifications we developed in consultation with electronic engineering personnel. Power outputs from individual transmitters ranged from 10 to 100 milliwatts (mw). Range testing in the gently rolling terrain of northeastern Colorado indicated that ground-tracking distances with truck-mounted dual beam antennas exceeded 40 km. Field tests were conducted using transmitters with traps and foot snares set for coyotes (Canis latrans) in California, black bears (Ursus americanus) in Oregon, and mountain lions …
