Welcome to Make the Adder Count 2024. Started in 2005, this long-running survey aims to encourage springtime counts of adders, with the objectives of informing local conservation projects/interests and gathering a long-term surveillance dataset.

Thank you to all the volunteers who have returned their data from 2021 and are helping to build up the dataset. We are now delighted to be able to present the results of the first 10 years, which are published in the Herpetological Journal:  pdf Gardener et al Make the Adder Count - population trends from a citizen science survey of UK adders.pdf (2.19 MB)

Make the Adder Count encourages experienced observers to gather data in a standardised way (by making at least three and, ideally, five or six counts of adult snakes basking after emergence from hibernation) so that information may be pooled to build a picture of trends in adder populations nationally.

The project is being co-ordinated by ARGUK. To take part please contact Angela Julian at: This email address is being protected from spambots. You need JavaScript enabled to view it.
