The effect of artificial light at night on the European bats

At the moment, the Milky Way is no longer visible to more than a third of humanity; light pollution is increasing faster than global population growth - changing the environmental conditions at night dramatically. At the same time, the effects on plants and wildlife are currently insufficiently understood. In this publication in EUROBATS, Jens Rydell and collegues focus on the situation for European bats, offering guidelines for consideration of bats in lighting projects.

Although the bats are almost exclusi­vely nocturnal and extremely sensitive to multiple effects of light pollution, its negative impact on bats alongside essential measures needed to pre­serve unfragmented nightscapes for these animals are often disregarded during impact assessments, planning and operation.

In this volume, the authors compile available evi­dence related to the effect of artificial light at night on the European bats. Based on the current state of knowledge, solutions are proposed concerning possible ways to avoid, mitigate and compensate the adverse effects which lighting projects may have on bats and their functional habitats. Research priorities for future studies, re­quired for in-depth understanding of the problem, are also outlined.

To "Guidelines for considerationof bats in lighting projects".

And for those who are more interested in bats, Jens Rydell et al. has just come out with another paper in Journal of Bat Research and Conservation where they present a remarkable display of bats in Cimetière du Père-Lachaise (the Père Lachaise cemetery) in Paris. You find it HERE!
