This spring, leading wildlife conservation charity People’s Trust for Endangered Species (PTES) is calling for volunteers across the UK to take part in its popular annual Living with Mammals survey, in a bid to track changes in our wildlife.

­Volunteers are needed to record sightings of any wild mammals they see each week in their gardens, local parks or other green spaces, such as allotments and churchyards. The results enable conservationists to better understand how our environment is changing, how these changes impact wild mammal populations, which need the most help and where conservation action is needed.
