Wildlife Damage Management Conference Proceedings
The California least tern (Sterna antillarium brownii) is an endangered, small (cm), ground-nesting shorebird that winters along the Pacific Coast of Central America and nests in colonies on coastal dunes and beaches from southern Baja to San Francisco, California. It was one of the originally listed species contained in the Endangered Species Act in 1970. Major nest sites remain at Marine Corps Base Camp Pendleton. During the past 15 years, adult tern counts have increased from about 300 to over 600 breeding pairs at the site. This poster provides results of an empirical analysis of annual fixed-cost agreements …

Wildlife Damage Management Conference Proceedings
The white-tailed deer (Odocoileus virginianus) may cause more damage than any other wildlife species. Deer damage occurs in various forms including crop production, automobile accidents, aviation collisions on runways, disease transmission, degradation of natural ecosystems, and destruction of ornamental plantings. One practical method of controlling deer damage is through the use of exclusionary fencing. White-tailed deer are challenging to exclude as they are able to jump 3.0-m fences or fit through spaces > 20 cm wide. Some deer problems (disease outbreaks, aircraft runways, and busy highways in deer migration corridors) may necessitate the installation of effective fencing no matter …

The National Wildlife Research Center (NWRC), based in Fort Collins, CO, is the research arm for the Animal Plant and Health Inspection Service’s Wildlife Services Program. Its mission is to resolve conflicts between wildlife and humans. The NWRC established a GIS (Geographic Information System) function in 1996. The relevance of GIS to two projects are featured in this poster. Project 1 was conducted in 1996 and was a joint effort between the NWRC and the California Department of Food and Agriculture (CDFA). In this project, 60 Chinese ring-necked pheasants were radio-instrumented and their movements studied. The main goal of the …
