On a delightful spring morning at Marden Park, just inside the M25 in East Surrey, we enjoy a walk with expert site manager Nick. He fills us in on how nature and people are benefiting from this special place and explains some of the challenges here too, including dealing with the effects of ash dieback and climate change.

Wildlife is thriving here thanks to the mix of woodland both young and old, veteran trees, rare chalk grassland and more. We see butterflies and signs of badgers during our visit, and volunteer Celia tells us all about efforts to help the endangered dormouse as part of the important National Dormouse Monitoring Programme.
