Home // Get involved // Surveys // Join our Mammals on Roads survey

To date, over half a million kilometres of road have been surveyed through Mammals on Roads. Its findings alerted us to the fall in hedgehog numbers and were the basis for projects such as Hedgehog Street and further research to uncover the reasons for the decline.

How does the survey work?

We want to know about your route and what you see along the way, dead and alive. This information is compared year to year, alerting us to changes in the wider population. Mammals on Roads has been running for 15 years enabling us to guide our conservation action where it is most needed. 

Journeys should include twenty miles or more on single-carriageways—in several sections or a single stretch—and should be outside of towns or built-up areas.

A passenger should record the sightings and the survey’s perfect for those summer holiday getaways! Why not get the whole family involved recording Britain’s mammals?
