The Friends of Westonbirt Arboretum charity works in partnership with the Forestry Commission to ensure that Westonbirt is supported, cared for and enjoyed. As the National Arboretum, Westonbirt is the UK's finest tree collection and one of the world's most important arboretums. It is also one of the most popular attractions in Gloucestershire and the Cotswolds. By joining us or giving your support, you can be part of the long-term future of this world class conservation site.
