National Pine Marten Monitoring Programme


Bringing together pine marten records
About the programme
The National Pine Marten Monitoring Programme (NPMMP) brings together pine marten records from across Britain to support the conservation and recovery of the species.
It combines data collected through monitoring by volunteers and professionals, sightings reported by the public to Vincent Wildlife Trust (VWT), and records shared by partner organisations, including Local Environmental Record Centres.
All data is collated through a GIS-based system, helping to build a national picture of pine marten distribution.
Supporting pine marten recovery
Pine martens are protected under the Wildlife and Countryside Act (1981), so monitoring must not disturb them. The den site of a pine marten is also protected from disturbance and pine marten den boxes should only be monitored by individuals following the guidance set out in the Pine Marten Den Box Monitoring Guide.
The programme collects data from non-invasive monitoring such as trail camera records at bait stations and den boxes, along with pine marten scats that have been verified through DNA testing. This work provides valuable evidence of where pine martens are present, if they are breeding and how the species is expanding into new areas.
By bringing this information together, conservationists can track recovery across Britain, target conservation action more effectively, and make the best use of limited resources.

Contribute your data
You can submit a range of monitoring data, including:
- Trail camera records at den boxes
- Trail camera records at baited and non-baited monitoring stations
- Pine marten scats (only those confirmed through DNA are included in Marten Map)
If you have an incidental sighting of a pine marten to report, please let us know.
