4.2. Flight route and passageway
There are some selected sites for the installation of wind turbines in Lebanon, which are near roads used by migratory SNX-5422 in spring and in autumn. Klaiaat and Quaraoun are two selected sites that are near a flyway used by migratory birds in spring, Daher El Baydar is near a flyway used by migratory birds in autumn. But, Marjyoun is nearly two flyway used by migratory birds, one in spring other in autumn . reported that the area used as a flight route and passageway has less risk of the wind farm, and in addition migratory birds pass once a year next to almost selected sites except Marjyoun, where they pass twice a year. So the likelihood of negative impact of wind turbines on birds in these sites is low.
Although birds can detect turbines, long lines of turbines have a potential barrier effect . Shorter turbine rows could reduce this effect, allowing birds to avoid them more easily. If the area is a passageway for migration birds, the rows of turbines could have this potential barrier effect in the migratory trajectories.
