Wildlife Welfare

Wild Harvest Mouse Welfare

Harvest mice are the UK's smallest rodent and face significant habitat loss from agricultural intensification. Conservation management maintaining suitable habitats protects their welfare.

Key Facts

Harvest mice build tennis-ball-sized spherical nests woven into tall grass stems
They require tall, tussocky grassland including reed beds and arable field margins
Agricultural intensification has dramatically reduced suitable habitat
Population decline has been significant but monitoring data is limited due to their secretive nature
Grass margin management under agri-environment schemes can benefit harvest mouse populations

Welfare Considerations

Harvest mouse welfare is linked to tall grassland habitat availability. Conservation management creating and maintaining suitable habitats benefits individual mice and population viability.

What You Can Do

Support agri-environment schemes that maintain tall grassland and field margins
Create harvest mouse habitat in gardens with uncut grass areas
Contribute to harvest mouse monitoring through citizen science schemes
Advocate for grassland management policy supporting small mammal conservation
