Wildlife Management
Background
The management of wildlife on and near airports is not usually an
easily solved problem. This management can be as diverse as habitat
manipulation to use of predators to repelling wildlife to lethal control of wildlife.
Types of wildlife associated with safety issues at airports include birds,
mammals and reptiles. This section contains sources/references the reader may
find useful in establishment of a personal management plan for their local airport
.
Birds
Birds' make-up 97% of the reported strikes, mammals about 3% and reptiles less
than 1%. (FAA) The large number of bird strikes has resulted in a major effort by
United States and Canadian airports officials to find ways to handle this problem,
including the establishment of a Bird Strike Committee.
The following resources provide information on controlling birds
at the airport:
Habitat
Animals are attracted to areas that reflect their natural
habitat and provide basic living needs such as food and water.
By understanding and controlling possible animal habitats at the
airport, wildlife strike risk can be reduced. For additional information
on habitat modification or other procedures for controlling hazardous
wildlife at airports, see FAA's Wildlife
Hazardous Management at Airports and the
Transport Canada Control Procedures Manual
Improving Awareness of Wildlife-management Issues.
Airport Planning --Airport planning
plays an important role in bird strike hazard reduction. Proper
planning of an airport can help to recognize land uses on or near the
airport site that can potentially attract wildlife. By controlling
these land uses, bird strike hazard can be reduced. From archival
data, it has been found that some of the most hazardous wildlife to
airport operations include:
- Gulls
- Waterfowl
- Raptors
- Deer
Land uses that attract these species of wildlife include:
- Putrescible-waste disposal operations
- Wastewater treatment facilities
- Wetlands
- Dredge spoil containment areas
Recognizing existing wildlife attractants, as well as mitigating the
creation of new wildlife attractants on or near the airport will help
to reduce the risk of wildlife strikes. For more information, see
the FAA Circular 150/5200-33,
Hazardous Wildlife Attractants on or Near Airports
and Transport Canada's
Bird Hazards - Discussion of Bird Hazards at Airports.
Habitat Deterrence --Improper landscaping can attract animals
to the airport and create wildlife hazards, while proper landscaping
can deter animals away. Some plants provide food or shelter for
potentially hazardous wildlife and should be avoided, while other
plants may repel wildlife. Habitat deterrence is an effort to create an
environment around the airport that is unattractive to potentially hazardous
animals.
For Information on deterrent landscaping see:
General Deterrents:
Other Habitat Information --Understanding an animal's
habitat is key to creating a habitat deterrence. The following resources
provide information as to the habitats of many different species.
Other Wildlife
Mammals are the most
common animals other than birds which are associated with aircraft strikes.
Mammal strikes are only a small per cent of the total recorded strikes,
but strikes with large ungulates including deer are extremely dangerous.
The number of white-tailed deer in the US has increased from 100,000 in
1900 to 26 million in 2000. In a ten-year period of 1990-1999 430 civil
aircraft were involved with collisions with deer.
