We collect data from various sources including our BDS deer app. The app is free and allows anyone to record and send us a deer sighting.
As wild deer are secretive and notoriously difficult to count accurately, recording their physical presence allows us to identify trends in spread or decline.
In addition, alongside our regular survey, we are also conducting a more comprehensive survey looking to deer abundance to establish actual densities.
The abundance survey volunteers visit a survey area within an allocated 1km square during Spring and Autumn and record the deer signs that they find.
HELP WITH THE DEER DISTRIBUTION SURVEY
Everyone can help with the British Deer Society deer survey including BDS members, wildlife groups, organisations, and the general public.
If you have a smartphone you can install our free deer app. The app has information on the deer species to help with identification and an easy report a deer sighting tool.
Even if you are not sure of the species you can simply snap a photo and attach this with your sighting and we can help identify the deer.
If you don’t have a smartphone you can still take part. Simply email your sighting including the date. time, location, species, number of deer and any observations to firstname.lastname@example.org.

SURVEY MAPS SHOWING THE CHANGING DEER PICTURE
The deer survey mapped results show both overall distribution and changes in the range of the various species over the five years since the last survey.
For the first time reindeer were included in the 2016 survey. As expected, a free-roaming presence was recorded in a limited area of the Scottish Cairngorms, while the remaining reports were of captive animals in zoos, parks, and other collections. This information is being consolidated and expanded on in the Society’s ongoing survey of Enclosed and Captive Deer.
Over the decades the mapped results have been acknowledged as the accredited record of where deer are located wild within the UK.
The British Deer Society maps are used widely by scientists, researchers, students, and the media and have appeared in books, scientific publications and been used to illustrate several countryside TV programmes.
