Helen Mark joins a group of asylum seekers as they help with a tree-planting project in Denbighshire. She hears how - without a car, and with rural buses both scarce and expensive - refugees rarely get access to the countryside. The group of people she meets have travelled to Wales from Liverpool for the day, but come originally from all over the world. She hears about the experiences of four of them - from Iraq, Iran, Namibia and Togo. They spend the day working alongside local conservation volunteers from the nearby village of Tremeirchion, sharing food, stories and songs. The project is organised by the charity Action Asylum, which has joined forces with the North Wales Wildlife Trust to get more than two thousand trees planted on former farmland near Offa's Dyke path. For the asylum seekers, who are not allowed to work while their cases are being assessed, it's a chance to contribute and do something constructive. With incredible views of the mountains in the distance and the Welsh coast spread out beneath them, Helen hears how working in the countryside is beneficial for both the environment and the refugees' mental health.
