Arbor Week

Arbor Week Logo

Trees are an essential part of California's climate and are vital to improving the state's air quality and water conservation. To help educate Californians on the value that trees provide to building successful, healthy cities and neighborhoods, California celebrates March 7-14 of each year as California Arbor Week.

CAL FIRE is partnering with California ReLeaf to encourage cities, nature groups, schools, and youth organizations to celebrate California Arbor Week by planting trees in their communities. California ReLeaf is an alliance of community-based groups, individuals, industries, and government agencies working to protect the environment by planting and caring for trees and the state's urban and community forests.

Research shows that trees clear pollution from the air, catch significant rainwater, add to property values, cut energy use, increase commercial activity, reduce stress, improve neighborhood safety and enhance recreation opportunities.

The goals of Arbor Week include educating Californians about trees, encouraging tree planting, teaching elementary school children the environmental, social, and economic benefits of trees, and protecting the state's valuable natural resources.

As part of the department's mission, CAL FIRE is charged with protecting California's forests by maintaining the sustainability of the state's natural resources including timber.
