Protecting Westonbirt Arboretum,
a national treasure

We are a charity with over 33,000 members who support The National Arboretum in connecting people with trees to improve the quality of life. Westonbirt Arboretum is a remarkable place with a beautiful and inspiring landscape where people can visit to enjoy and learn about trees.

With 15,000 trees specimens, 5 national trees collections and seasonal activities for all, visitors can come along to Westonbirt throughout the year and be met with a whole new environment as the seasons come and go. There's always something new to discover. A membership with us allows you to be a Westonbirt advocate, caring for one of the world's most extraordinary arboreta and gives you access to enjoy the arboretum, wander amongst the trees while protecting a cherished part of the Cotswold's much-loved landscape.

Never before has the need to adapt and prepare for the future been so great or your support been more vital.
