Abstract

To predict the most hazardous areas for collisions with wind turbines by greater white-fronted geese Anser albifrons around their stopover sites, the relationship between flight altitude of geese and the distance from takeoff sites was studied at lakes Izu-numa and Kabukuri-numa in February 2009, the period when the geese started their spring migration. The model showed that the geese reached a low risk altitude, over 100m, at 3km from the takeoff sites. It suggests that the risk of collision with wind turbines by greater white-fronted geese decreases to a minimum in areas further than 3km from stopover sites, because most wind turbines currently used are less than 100m in height.
