Brown hares have declined significantly in the UK and face welfare threats from agricultural intensification, coursing, and changing land management practices.
Brown hares suffer welfare impacts from agricultural operations including nest destruction by spring cultivation, mortality from harvesting machinery, and loss of the field margin habitat that provides shelter and food in winter. Leverets left by their mothers are sometimes incorrectly assumed to be orphaned and picked up by well-meaning members of the public, which causes distress and usually reduces survival chances. Illegal hare coursing, despite the legal ban, continues in some areas and causes acute welfare harm through exhaustion, injury from falls, and dog attack. Hares that escape coursing dogs suffer prolonged physiological stress even when physically uninjured.
