The hazel dormouse faces multiple welfare challenges from habitat loss in the UK, with population declines of over 70% making targeted conservation and welfare interventions increasingly urgent.
The welfare concerns for dormice extend beyond population conservation to individual animal experience. Animals that wake from hibernation during warm spells in winter burn energy reserves without food being available, potentially dying from starvation or cold when temperatures drop again. Habitat fragmentation forces dormice to cross open ground to reach other woodland patches, exposing them to predators like domestic cats and vehicles. Poorly timed woodland management operations can disturb nest boxes and hibernating animals, causing potentially fatal cold exposure. The species' extreme sensitivity to disturbance means welfare and conservation interventions must be conducted by trained personnel only.
