Hello from Glasgow-ish.
Hello from North Devon
Hi from Edinburgh
Fiona, If we want to reduce the impact on bats, what colour should we advise people to use when illuminating their drives/gardens? Thanks
Hi Andy, I suggest using as little light as possible (ie low lumens), focus it just on the drive rather than shining it up into the sky, and switch it off when it isn't needed.
Thanks, I am dealing with a man who wants to use a lot of lights and refuses to reduce them in numbers. Although not committing a criminal offence I would like to direct him to changing the colours if that would reduce the impact. They are mainly yellow at the moment, thanks
Re. colours, generally warmer colours are considered better for wildlife. As I mentioned, it's a bit complicated in terms of how much different species benefit (dark being consistently best!) but blue and Ultra-violet not good for mammals and invertebrates. Try to avoid halogen.
Thanks, will make sure he doesn't use halogen and steers away from blue
I’m so sorry I have to rush out. I really hope this is recorded so I can catch up later. thank y everyone
I heard Redwings the other night
So, all of the speakers this evening have spoken primarily about static lighting, but I wonder what research, if any, is being done on the possible effects of transient lighting events? (e.g. passing-by of a vehicle headlights.)
Very good point about transient lighting. It is actually quite difficult to study because headlights are linked with other factors such as noise, pollution etc. However, we have far more unlit than lit roads, and on many of these, there is considerable light from headlights. It would recommend always using permanent barriers (such as earth bunds) rather than fencing as a light barrier as the latter tends to be removed/falls down over time.
I have unfortunately got to shoot off but thank you everyone it was very interesting
Really interesting talks. Thank you to all presenters.
Very fascinating thank you all presenters
thanks all, very interesting and good to know there are a few options to take away to recommend for future developments (warmer lights and part-lighting)
Thanks for your responses folks!
Boyes, Douglas H.
Here's a review looking at the ecological impacts of headlights: https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/1365-2664.13157
Cheers Douglas (p.s. like the shirt!)
Thank you Katy and to all the speakers lots to think about.
Excellent speakers. Thank you. Perhaps a petition to get street lights turned off in villages earlier?
thanks - really enjoyed it
thank you all. Really interesting :)
Thank you - very interesting
