California Arbor Week

California Arbor Week works to unite our members, cities, businesses, and individuals to educate Californians on the value trees provide to building successful, healthy cities and neighborhoods. An important message every day of the year, March 7-14 is a chance for Californians of all ages to celebrate our natural wonders and most treasured resources together. Be a part of California Arbor Week. Plant a tree. Join in a community event. Teach our youth.

The California State Assembly and Senate have approved Resolution ACR 10 (Dickinson) establishing March 7-14 of each year as California Arbor Week. The measure urges all California residents to observe the week with appropriate tree planting activities and programs.  The resolution (ACR 10) was introduced by Assemblymember Roger Dickinson and was sponsored by California ReLeaf.

ACR 10 recognizes that trees are a vital resource to our communities and serve as an important link with nature for California’s residents. Trees are a valuable economic asset in our cities and towns and play a role in energy conservation, improving air quality, protecting water resources, providing habitat, and contributing to the overall health of residents.
