​​​​​​​​​​​​​​​​​Tree Buddy Trails

​Tree Buddy Project - creating tree trails in Blackburn

This volunteer project focuses on the trees in Blackburn; finding out more about their stories and benefits and sharing these with visitors and locals.  The initiative celebrates the many historic trees we have within the town and helps to protect them for future generations.

A number of volunteers embarked on this project in Summer 2022.  Their work has helped Blackburn BID to create and launch guided tree trails through the town centre.
