unting is the most important tool available to wildlife managers. Sportsmen and women spend countless hours afield pursuing whatever species they favor, helping manage wildlife populations in the course. They also provide this valuable service for free, and contribute millions towards conservation in the process. This devotion has led to the rebound of a number of species, including whitetail deer and the Eastern wild turkey. The monies from license sales and excise taxes is used to manage lands, both game and non-game species, and a number of hunter-supported conservation organizations performing valuable research. But there are certain areas where hunting cannot be used as a management option. Some such areas are airports. Getting around an airfield has many special challenges, with movement through some areas being coordinated by the tower or ground managers. In the case of commercial airports, security clearances are required as access to aircraft is strictly controlled. While there are other government and private agencies that perform animal control work on civilian airports, the United States Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services is the most prolific. Wildlife Services is the agency that is charged with alleviating issues caused by animals on a large scale. WS conducts disease monitoring and abatement in animal populations, such as avian influenza surveillance and inoculation of rabies vectors, dealing with animals that carry and transmit the deadly disease with bait drops or traps, as well as vaccination-and-release programs. Another specialty is population management of keystone species to limit habitat damage and agricultural loss. They are perhaps best known, and vilified, for aerial shooting of coyotes in the West.
