Thank you to the donors, sponsors, volunteers, and community partners who continue to move
The Britton Fund forward. As we celebrate 20 years of caring for trees together, your engagement in 2026 helps turn ideas into action — supporting research, advancing education, and
strengthening the tree-care community across the West and beyond.
We are grateful for your continued support. Together, we care for trees.
