Tiny Harvest Mice Hunted in Scotland's Largest Nature Reserve
2 Feb
Summary
- Surveys are planned to confirm the presence of critically endangered harvest mice.
- Nests were recently discovered in Tarras Valley, suggesting a potential population.
- Tarras Valley Nature Reserve is one of the UK's largest community-led projects.

Southern Scotland's Tarras Valley Nature Reserve is initiating a hunt for the UK's smallest rodent, the harvest mouse. This species is considered critically endangered in Scotland. Recent discoveries of woven grass nests on the 10,500-acre reserve have sparked hope that a population may inhabit the land.
The Tarras Valley Nature Reserve is a significant community-led initiative, having expanded significantly since its inception. The finding of harvest mouse nests was unexpected by reserve management.
These surveys are part of a national effort led by the Mammal Society. Reserve managers are eager to confirm the presence of this scarce species, which would further enhance the reserve's status as a haven for wildlife.
