The government plans to plant 30,000 hectares of trees each year by 2025. But how practical is it and what would the real impact be? Eleanor Rosamund Barraclough talks to Dr Julie Urquhart of the University of Gloucestershire about why we need more information about carbon capture to help select the best places and the best tree species to plant. William Macalpine is based at Rothamsted – his project explores how cutting back and coppicing willows as a crop encourages a rapid growth cycle and replenishment. His presentation Willow Power at the 2008 Chelsea Flower show demonstrated the versatility of willow and the number of varieties. He argues we need longer term funding and to break the 5 year funding cycle for farmers, and researchers. Dr Julie Urquhart is Associate Professor of Environmental Social Science at the University of Gloucestershire. She’s an ambassador for the Future of UK Treescapes programme, a collaboration funded by UK Research and Innovation, the Scottish and Welsh government and DEFRA.William Macalpine is a willow breeder at Rothamsted Research, looking at shrub willows as a sustainable energy source. He is also a Chelsea Flower Show Gold Medal winner, for a display entitled ‘Willow Power’.
