Reports note that Gladsaxe replaced its standard white LED fixtures with specialized red LED streetlights along Frederiksborgvej. The installation was strategically placed near a known bat colony to mitigate the impact of artificial light on the nocturnal ecosystem. By shifting the wavelength of the light, the city sought to maintain essential road safety for drivers while protecting the natural behaviors of local wildlife.
The project identified the common pipistrelleand the brown long-eared bat as the primary species targeted by this conservation effort. These animals rely on specific dark corridors for navigating between their roosting sites and their feeding grounds. When traditional white light spills into these areas, it can create “light barriers” that the bats are often unwilling to cross, effectively shrinking their available habitat.
We did? I should probably go into town and have a look
Let me know what you find. Bonus points if you spot a bat.
Went for a bit longer evening walk with the dog, so I could look down into the village. The lamp I could see was just normal yellowish, I didn’t check the other one, but I don’t think that someone would only change one and not the other.
First I’m hearing of it…
Picture please
Apparently it’s one street near our capital. That’s a 4 hour drive each way and a total bridge toll of about 60€… I wanna see it, but not that bad
Circadian rhythm in animals?
Bats not willing to cross illuminated areas.
Pretty sure they have to be invited.
Only if someone lives in that illuminated area. And only if the bat in question likes blood.
Some bats. Bats where I live take full advantage of the street lights.
The bats where you live don’t follow janteloven. “Do you think you’re special enough to go to the light? You are not better than us, you little shit! Get back into the dark!”
Yay Bats! Yay Denmark!
I wonder if the red light would not be visible when the bright light of oncoming traffic wash out your night vision.
Denmark just got Mario Kart for the VirtualBoy?
