Abstract: Wind power construction and plans for further construction projects have given rise to concern as to their impacts on birds and bats. Collisions of these species with wind turbines have been reported round the world. The review concerning the impacts of wind power projects on birds and bats in international peer-reviewed literature and reports on the impacts of wind power on these species, commissioned by the Ministry of Economic Affairs and Employment, was conducted on 1 March–30 May 2017. Based on the literature, birds and bats collide with wind turbines in in highly varying numbers, and the location of the turbines is important in terms of collision mortality. There is also considerable variation in the susceptibility of different species and sub-species to collide with wind turbines. In some places large numbers of birds and bats have collided with wind turbines built in unfortunate locations in terms of these species, but hardly any impacts on their population size have been observed. In the case of bats, in particular, lack of information on the ecology and population size of the species makes it difficult to detect changes in the population. For some bird species the disturbance and blocking effect of wind turbines may be more significant than collision mortality, but in most cases these impacts are restricted to the immediate vicinity of wind turbines and no impacts on the population size in larger regions have been observed. Based on research the building of more wind turbines in Finland is not likely to cause a significant threat to bird and bat populations, if the turbines are located in areas where their population densities are low and the risk of collisions can be minimised. However, there is not yet enough information on the impacts of wind turbines on birds and bats, and further studies and monitoring are needed to make sure that new wind power building projects will not affect the population sizes of species that are susceptible to collision in the future. In Finland, in particular, more research focused on bats and long-term monitoring of the impacts of wind turbines after they have been built are needed.
