German mayors call for night-time ban on robot lawnmowers to protect hedgehogs

Leaders say automated mowers' blades threaten nocturnal animals as studies highlight risks to wildlife

German mayors have called for a nationwide ban on night-time use of robot lawnmowers to protect hedgehogs and other small nocturnal animals from being killed or maimed in the dark.

Recent studies have highlighted the threat lawnmower blades pose to wildlife active between dusk and dawn, prompting growing calls for regulation. Hedgehogs also tend to curl into a ball when threatened rather than running away, making them harder for a robot mower's sensors to detect.
