Last year, we ran a pilot across six Dartmoor parishes: Buckfastleigh West, Chagford, Dunsford, Horrabridge, Ilsington and Mary Tavy, and asked residents to let us know where house martins are nesting. This year we are extending the project to all of Dartmoor. You can now submit sightings of house martin nests anywhere within the Dartmoor National Park area.
