More about city lighting....and it's effects on urban species
Kingston/Elmbridge Riverside so-called wildlife corridor Hale et al have just published another interesting paper that found that even for the most common species of bat in urban areas, lighting can act as a barrier to movement, so the fine-scale positioning of lighting can be critical. Gaps in tree lines should be narrowed and light levels minimised. Also, bats seem to cross in the darker parts of gaps, implying that lighting has additional costs/risks that the bats are trying to minimise see here: Gap crossing thresholds for urban bats This and similar papers can be downloaded from the Lights and Wildlife Yahoo Group. Lighting around my house from space With this in mind, consider the effect of urban densification and light pollution on the town centre neighbourhood by the Old Post Office development proposed by St George with its 19 storey glass towers. Many species reach a tipping point when the amount of built surface rises above 60% of the built environment.Thi
