NI Mammal Recording Project

The Centre for Environmental Data and Recording (CEDaR) is based within the Curatorial Department of National Museums NI and is a partnership with NI Environment Agency (NIEA) and the Environmental Recorders’ Group (ERG).

CEDaR has been operational for 30 years and has led the way on the wider recording of a diverse range of species Groups, both within NI and across the island of Ireland.
Mammal recording has always been an important element of our activities, and the Centre has been involved with a number of recording projects since 1995.

To celebrate the 30-year milestone, and as part of a variety of events, the Centre has launched its latest recording initiative. The NI Mammal Recording Project (2025–29), marks the twenty-fifth anniversary since the completion of its previous bespoke mammal recording scheme (1995–2000), and provides a contemporary focus on our knowledge of the status and distribution of mammal species throughout Northern Ireland.

This latest project will combine the involvement of Citizen Science recording, with current activities based within University Departments, the wider eNGO sector, etc.
We encourage all active recorders to continue the submission of their mammal sightings. When verified and validated, these sightings will be collated within the copy of the Recorder 6 database at CEDaR.

To widen the recording base, and to facilitate currently interested recorders, we anticipate rolling-out a programme of training courses. Watch out, as these will be advertised in future copies of the CEDaR newsletter.
If there is a requirement for equipment, e.g., camera traps, etc., you may wish to consider becoming a member of ERG and applying for funding!

Further details for this NEW recording project will become available in due course.
In the interim, please continue your recording activities. We are always very appreciative of your efforts and the continued flow of records to the Centre.

Keep a look out for all mammal sightings, both alive and dead, and send through to CEDaR on the form below.

Notes about using the map:
  • use the + sign on the right hand side of the map to change the base mapping used from Google to OpenStreetMap.
  • To create an accurate and useful record, use your mouse to drag the area of interest to the centre of the map window and use the zoombar on the left hand side to zoom in tight to the area where you made the sighting. When you have zoomed in, click on the location - this will autofill the Spatial Reference box above.

Please tick all the species you saw and any other information about them.

Determiner: if you have had an expert confirm the identification of a record please add their name in the 'Determiner' field. This will help when the record is being verified.
