Zoologist conducts experiment to keep the skies safe for aircraft

Li Dong grows plants to ensure the safety of aircraft.

The 33-year-old hopes that planting Wedelia trilobata, a low-growing species with yellow flowers and a special smell, will keep birds away from the Nanning Wuxu International Airport since there is no food or nesting space for them.

As there are more flights than before and China's ecology is improving, birds are a major problem in civil aviation. Collisions often occur during takeoffs, the initial climbs and landings, and pose a significant threat to aircraft safety.
