Conservation of small mammals including yellow-necked mice and harvest mice in UK agricultural and woodland habitats.

Key Facts

Harvest mouse populations have declined significantly due to habitat loss
Harvest mice build intricate spherical nests woven into grass stems
Yellow-necked mice are associated with ancient woodland and old orchards
Both species are monitored through the National Small Mammal Survey
Grass margin creation at field edges supports harvest mouse populations

Welfare Considerations

Small mammals face welfare risks from agricultural intensification and loss of hedgerow and grassland habitat, with field margin management delivering direct benefits.
