A new era for forests
Building on the momentum of the 9th American Forest Congress, a landmark gathering that called for a new era of forest stewardship, we welcomed more than 1,200 participants across 42 events at Treehouse. Partners from philanthropy, policy, conservation, Indigenous leadership, finance and technology came together to explore how forests—and nature more broadly—can shape the future of climate solutions.
