Help to put Mammals on the map

Herefordshire Mammal Group (Previously known as Herefordshire Action for Mammals - HAM) is dedicated to the conservation of mammals in Herefordshire.  We aim to teach people about mammals and to encourage them to learn more about them by taking action themselves. 

Our activities include recording the distribution and population size of mammals throughout Herefordshire, conservation work, workshops and training days, talks and visits, providing advice on species and habitat conservation and identifying threats to local habitats. We also provide opportunities for students to expand their practical experience in working with mammals. 


Events are added to our website as they become confirmed.  Many are first listed on our FaceBook page.  Some events may not be advertised for various reasons, so if you have a particular interest please contact a member of the committee or the species co-ordinator

Check out our Events Calendar for full information.
