Impact of light at night: preventing habitat loss and habitat fragmentation by adapting night-time illumination

The Light-on-Landscape project provides essential information on how to effectively mitigate the impact of light pollution on wildlife at night. It resolves a key problem in the prevention of habitat loss and landscape fragmentation for nocturnal species: the lack of knowledge on the threshold light intensities at which species abandon their habitat, or stop using crossing structures and corridors when moving around in a wider landscape. These thresholds are expected to vary with the spectral composition of the light, but these may also be different for novel, adaptive lighting measures. Here, we investigate whether dark or low-light zones prevent habitat fragmentation, and how lighting designs can avoid negative effects on wildlife corridors crossing roads. We do this by establishing the distance-response relation of four nocturnal species groups to light with different spectra. These groups – bats, mice, mustelids and amphibians – are strongly dependent on landscape structures. We explore the effects of adaptive lighting and maximize its effectivity by optimizing its characteristics, such as intensity differences and switching time.
