The beaver, this genius of riverbank engineering, this manager of wetlands like the Lys, this ancestral architect. Many nicknames. But who is he really? Signs of his presence have been found on the Prés du Hem. Among other things, he left us pencils, whistles and chopsticks. If you'd like to find out more about the traces he leaves in his wake, his diet and his way of life, come and discover with us.
We suggest that you divide the activity into two parts. A first part in the classroom and a second part in the field.
