German mayors are taking a stand against the nightly use of robot lawnmowers, citing the need to protect hedgehogs and other small nocturnal animals from harm. This issue has gained traction due to recent studies highlighting the threat lawnmower blades pose to wildlife, especially during their active hours between dusk and dawn. Hedgehogs, in particular, are vulnerable due to their instinct to curl into a ball when threatened, making them harder for robot mowers' sensors to detect.
The call for a nationwide ban on night-time lawnmower use comes from Claudia Kalisch, the vice-president of the German federation of cities and the mayor of Lüneburg. She emphasizes the importance of green spaces for both animals and humans, especially in urban areas where property development and intensive agriculture encroach on natural habitats. Kalisch argues that a ban is a logical step to protect wildlife and enhance the quality of life in cities.
The concern extends beyond lawnmowers; motorised leaf blowers and vacuums also pose risks to hibernating hedgehogs. Additionally, road accidents are a significant factor in the decline of hedgehog populations across Europe. Researchers at the University of Oxford have made significant strides in understanding hedgehog behavior, discovering that they can hear high-frequency ultrasound. This finding has led to the development of sonic repellers as a potential solution to keep hedgehogs away from dangerous roads.
The impact of robot lawnmowers on hedgehogs is particularly concerning. Injuries from these machines place a significant burden on animal care centers, and many hedgehogs with cut injuries are found days or weeks after the accident, enduring considerable suffering. German law already protects hedgehogs, with fines of up to €65,000 for trapping, injuring, or killing them.
While several German cities have already banned night-time use of robotic lawnmowers, a statewide ban in Bavaria failed to pass. However, the movement continues to gain momentum, with mayors and citizens alike advocating for the protection of hedgehogs and other wildlife. The future of hedgehog conservation in Germany remains uncertain, but the efforts to date demonstrate a growing awareness of the interconnectedness of human and animal well-being.
