The dormouse is listed as Vulnerable on the IUCN Red List due to significant population declines.
Threats
Habitat fragmentation and loss
Intensive agriculture
Climate change affecting hibernation patterns
Conservation Efforts
Woodland preservation and rewilding projects
Reintroduction programs in protected areas
Legal protection in the UK under the Wildlife and Countryside Act
Conservation efforts focus on habitat restoration and reducing human impact on dormouse populations.
