Many studies have shown that wind farms can have negative impact on bats. Records of dead bats under wind turbines were discovered in different countries, in some cases reaching very high numbers (ex. Ahlen 2003, Johnson et al. 2003, Kerns &Kerlinger 2004, Arnett 2005), however, it is not well understood, why bats collide with wind turbines (Ahlen 2003).
In Croatia, two wind farms were built near the Adriatic coast, on in 2004 and the other in 2006. Recently, few sporadic checks of areas under the wind turbines revealed bat casualities at both locations. Record of one finding was reported in Slovenian bat magazine (Jancar 2006). Here we summarize all records of dead bats, found under wind turbines in Croatia.
