The test will "greatly aid hedgehog conservation, by enabling manufacturers of robotic lawn mowers to ensure their models are hedgehog-friendly before they are put on the market," according to lead researcher Sophie Lund Rasmussen. "Cut injuries from robotic lawn mowers are placing an enormous burden on many hedgehog care centres and using up important resources, as these injuries often require above-average care and treatment," said Anne Berger of the Leibniz Institute for Zoo and Wildlife Research.t machine mowers.
