British hedgehogs have declined by 30-50% since 2000 due to habitat loss and fragmentation. Understanding their welfare needs in urban and rural environments helps conservation efforts.
Hedgehog welfare in agricultural and suburban landscapes is directly shaped by human management decisions. Metaldehyde slug pellet use causes direct poisoning that produces convulsions and organ failure over hours — a welfare concern for thousands of individuals annually. Strimmer injuries from cutting unmown grass or leaf piles cause severe, often fatal wounds in animals that shelter in vegetation. Road mortality contributes significant annual deaths, particularly of juveniles dispersing in autumn. Garden pond drowning — hedgehogs that fall into ponds without exit ramps — causes unnecessary mortality. Each of these individual welfare harms is preventable through simple management changes. The population decline trajectory, if continued, represents welfare harm at scale as individuals living in increasingly fragmented landscapes face starvation, reproductive failure, and isolation. Urban gardens connected through Hedgehog Highways and managed with wildlife in mind provide some of the best remaining hedgehog habitat.
