Submit records to the National Mammal Atlas

Mammals in the British Isles are under-recorded, resulting in a lack of knowledge about where mammals are or how well they're doing, which hinders conservation progress. The National Mammal Atlas Project (NMAP) aims to produce the first atlas in over 20 years to present vital new baseline distribution data, which will be continually updated through ongoing monitoring, to effectively inform future conservation decisions.

The Mammal Society is working to collate existing records from various sources, but we also need YOU to submit records online here whenever you see a mammal or their signs to fill the gaps on the maps! We need records for all species, common or rare.


NMAP is collecting data from ad hoc sightings and in parnership with record centres. Derek Crawley, Atlas & Local Groups Officer on Council, is overseeing this currently. Two funded regional projects MaMoNet Wales and MaWSE additionally support data collection. Email or for more information. 

What Happens to my records submitted online?

Your records, once submitted to our online form, are stored with the Biological Records Centre's (BRC) iRecord database, where they will be verified for accuracy.

Eventually our records will be uploaded to the National Biodiversity Network (NBN) Gateway, the "data warehouse", to add to existing record sets.

What if I can not identify what I have seen?

If you can not ID what you've seen, and have a photo, visit iSpot, where a community of mammal experts can provide an identification for you. iSpot will then forward your record to us for inclusion in the atlas.

You can also ask your local County Mammal Recorder, who will be a local expert and can discuss your sighting with you and tell you what you are likely to have seen. Many CMRs are also verifiers of records for NMAP.

What about records submitted or held elsewhere?

We are working with local record centres and national datacentres to regularly share information in an open process. If you have submitted records to a local recorder or scheme that you know shares data with the BRC or NBN, you don't need to submit them here. Most local recording schemes will do this. They are usually either dedicated organisations, or based with the local authority or wildlife trust. County mammal recorders are also usually affiliated to them.

Where can I find my local record centre?

There are record centres covering every county in the British Isles and are coordinated through ALERC in England, BRISC in Scotland, LRCWales in Wales, and CEDaR in Northern Ireland.

What if I have large numbers of records to submit?

Large record sets can be submitted directly to and will be uploaded to the atlas. They can be sent in any form.    

How does The Mammal Society work with others to monitor mammals?

The Joint Nature Conservation Committee (JNCC) is a public body of 24 partner conservation organisations, co-ordinated under DEFRA that advises the Government on UK and international nature conservation.

The JNCC established the Tracking Mammals Partnership (TMP) in 2005 to improve the quality, quantity and dissemination of information on the status of mammal species. While the TMP is less active, The Mammal Society has taken the lead in ensuring more mammal information will be openly available through the development of the National Mammal Atlas Project.
