Politicians keep promising more trees – seen as good for the environment and for fighting climate change. Trees are also big business sustaining vital rural jobs. So will lots of new planting keep everyone happy? Chris Bowlby explores forestry’s future in one of its key locations – Northumberland. He visits the huge forest at Kielder, and a rural factory turning thousands of logs into essential materials for millions of British homes. But there are problems too – a thicket of bureaucracy surrounding planting, and questions about what sort of trees really do bring environmental gain.
