The Arnold Arboretum relies on the strength of a dedicated community of supporters that respects the beauty and wonder of the natural world. You can make a difference!

In 2023, we relied on gifts from current members and donors to cover 17% of our $19.5M annual operating revenue. In addition, we are fortunate that past and present donors have established endowments that fund most of the remaining 83% of our expenses. We need your financial help to keep our landscape vibrant and our research and educational mission active. Join or renew as a member, make a one-time gift, initiate a commemorative bench dedication, or consider a planned gift to help us plan for the future.
