National Dormouse Database (NDD)

This dataset is a collation of individual records of dormouse sightings and/or evidence from England and Wales mostly between 1988 and 2022, although there are a few earlier records. Records originate from a variety of sources, with the collation held and maintained by People's Trust for Endangered Species (PTES). It is an incomplete directory of sites due to the ad-hoc nature of data collection. Some sites are regularly monitored using nestboxes as part of the National Dormouse Monitoring Programme (NDMP) ñ these sites are indicated in the attributes and more detailed biometric data are held by PTES who administer the monitoring programme. The original database held by PTES includes the record source but this is not included in the Atlas version.
