Reducing birdstrike risk Ian Witter, BAA Airside Operations Reducing birdstrike risk You cannot guarantee to prevent birdstrikes, but you can do things to reduce the risk. Numbers of birdstrikes do not tell you much about the risk

Bird Control
On site, continuous bird patrol, mobile in a vehicle Trained staff Equipment to scare birds – distress calls, shellcrackers Log all activity Include off airport monitoring of known attractants and overflights

Habitat Management
Key factor is to understand and reduce attractiveness of airport Grass management
long grass policy, 15-20cm, regular topping cuts Bottoming out spring, dense thick upstanding sward Fertiliser, Herbicide, Insecticide – soil sampling
Management plan to reduce attractiveness
net water bodies bird proof buildings etc etc

Risk Assessment for each airport
- Historical strike data
- Birdstrike species identification – very important – you can help!
- Probability - based on average number of strikes
- Strikes over 5 years, average per rolling 5 years by species
- Severity - UK National damage figures for each species
- Matrix – High/Med/Low – Red/Amber/Green
- Purpose is to prioritise to reduce damaging birdstrikes
- BAA uses the measure – the number of birdstrikes with species
classed as high or medium risk each month or year.
This better describes the risk than using the total number of birdstrikes,

Audits & Safeguarding
Internal BAA audits CAA Aerodrome Licensing audits FERA detailed risk assessment and standards check every year
check bird control skills, techniques, equipment check off-airport attractants and monitoring regime
Safeguarding process
Town and Country Planning Consulted on proposed new developments – bird management plans 10 in place, plus hundreds of flat roof planning conditions (gulls)
