The Arbor Day Foundation’s Alliance for Community Trees network is composed of community-based organizations dedicated to planting and caring for trees. These passionate nonprofits are the boots on the ground — the purest and best definition of grassroots. Their hands are in the dirt; their impact is undeniable. And as a unified force, they are changing towns and cities across the country.
Vibrant Cities Lab has a new look, new resources and new ways to get involved in greening your city. We’re introducing several new digital resources including a Cool Corridors Guide, Urban Forestry Roadmap and Forest Health information that will help urban foresters and related professionals build thriving programs for their communities. On December 31, 2025, old.vibrantcitieslab.com (note the new URL) will close. Make sure you download any resources or action guides you don’t want to miss. Get involved with us by sending your feedback on the new website or sharing your best urban forestry success stories with us at info@vibrantcitieslab.org.
