Students following the PRIDE and XL courses at Tenby's Greenhill School in Pembrokeshire spent the last two days of term planting 20 free trees to enhance their school grounds and social areas, thanks to a joint initiative by National Grid and Pembrokeshire Coast National Park. The trees, including beech, oak, wild cherry and sweet chestnut, are part of a 400-sapling donation to the National Park by energy company National Grid. During its recent essential maintenance work on their high-voltage overhead transmission lines bringing electricity to West Wales, the company had to fell 100 trees. Thanks to National Grid's policy of planting four new trees for every one removed, local schools such as Greenhill and other organisations have benefited through bidding to the National Park for the trees. Helping with the tree planting, National Grid project manager, Wayne Hewson, said: "The PRIDE course carries out a range of excellent alternative project work with 14 to 16-year-olds who have difficulty coping with mainstream education. Thanks to this National Grid initiative, they have been able to learn through the land and it's great that both they and the school will benefit from this. "National Grid works in partnership with the Tree Council to provide native trees for suitable locations such as this. Staff and pupils will be able to benefit from the trees for many years to come and we've been very impressed with the enthusiasm and dedication everyone has given to the initiative," Wayne added. Greenhill head of Vocational Studies, Carol Hicks, said: "Projects like these help young people fulfil their potential. Society is in need of a range of different skills and activities such as the tree planting scheme have helped give our PRIDE students a start in developing a number of skills to meet these needs.
