Other Mammal Data from National Dormouse Monitoring Programme (NDMP)

Quality Control

All records are from fully trained and licenced dormouse monitors often with several years surveying experience. Recorder names are held by PTES in the original database. All records have been checked using the NBN Record Cleaner.

Method steps

1. Standardised nest box checks are carried out by fully trained and licenced dormouse monitors as part of the National Dormouse Monitoring Programme (NDMP), which is coordinated by People’s Trust for Endangered Species. All records will be of animals found in the boxes, some of which may have additional biometric data held by PTES. Data are then entered online by the monitors.

England and Wales. The hazel dormouse does not occur in Scotland or Northern Ireland. The dataset is biased towards places where NDMP sites have been set up, with higher concentrations of sites potentially occurring in counties where proactive mammal/dormouse groups exist. Grid references normally refer to the centroid of a wood/woodland parcel rather than the actual sighting location.
