Fences are the most important tool to control mammals at
airports with recommended heights between 3.0 m and 3.7 m, and
configurations employing barbed wire, razor wire, outriggers, and
Electrobraid deer fencing. A successful integrated approach to
animal management includes lethal control. However, airport
managers must ensure that animal suffering is minimized and
concurrently eliminate attractants while implementing lethal
control measures in order to provide a long-term solution. Culling
remains an immediate but short term animal management technique.
A zero tolerance policy for deer and other large mammals in
airport operating areas has been recommended by Cleary and
Dolbeer (2005). Lethal control has also been used to curtail populations
of coyotes (which chew electrical lines), rodents (which
attract predators) and bird populations. Although expensive and
with some operational limitations, falconry can be effective for
controlling birds. The Falco Robot GBRS, a natural looking, remote
controlled flying device, has also been tested with some success
(Iori et al., 2009).
