| | | Bats and Lighting
I was down at Slapton and on the campsite was a black Landrover with the legend "Bats and Lighting" ( I thought it was a band at first) they were doing a survey of the effects of lighting on local bats. I have not read the results yet. Bats and Lighting Research Project http://www.bats.org.uk/pages/bats_and_lighting.html

I think there is quite a bit of research into this because the known impacts are rather fuzzy and complex. Some species are happy to forage around lights, drawn in by the insects trapped by the light (pipistrelles and serotine for example) while other species are actively deterred by lighting (brown long-eared bat and horseshoe bats).
Add to that potential confusion resulting from lighting effectively reducing invertebrate numbers because the trapped adults don't get to breed and lighting increasing the populations of some bats which then out-compete the species that are deterred by light.
I recommend a book called the 'ecological consequences of night lighting', its an easy read and very interesting.
but for there to be enough work to pay for a nice branded landrover I'm quite surprised!

Emma was chairman of The Avon Bat group. I met her on the campsite and we looked at each other for a while until I said "Avon bat group?"
Slapton with its Ley and reed beds and the wooded areas inland support several bat species, these are attracted to the warm air above the site shower block for the Moths and insects

Not that I have managed to watch much of Autumwatch but I did catch a bit about street lighting in London. They are installing LED street lights which apart from using less energy also create less light polution with the light only going straight down in a narrow beam, they also switch off with motion sensors for people passing by and hence should help the bats (well apart from the ones that don't mind the lights and the insects attracted). There is no UV either to attract the insects. | | |
