A Critical Time for Preserving The Arroyo Seco

This is a very exciting and dynamic time for the Arroyo Seco—that great canyon that flows through our communities to link the San Gabriel Mountains all the way to downtown Los Angeles. We been able to accomplish a lot recent, and now plans are being developed along the Arroyo to restore more natural conditions and to promote ecosystem health and biodiversity.

Your contribution will help support vital preservation and restoration efforts, volunteer activity and educational campaigns, while protecting our region's greatest natural treasure for future generations. Please give generously so that we can continue and expand our work to protect and enhance the Arroyo!
