Learn about the benefits of urban trees
Trees improve the quality of the air we breathe.
Trees remove carbon dioxide from the air by sequestration.
Trees filter air pollutants, including ozone and particulates.
Trees produce life-supporting oxygen.
This recent study from the US Forest Service Northern Research Station suggests that trees’ improvements to air quality help humans avoid more than 850 deaths and more than 670,000 instances of acute respiratory symptoms in a given year!
Trees help Californians store, clean, process, and save water.
Trees help keep our waterways clean by reducing stormwater run-off and soil erosion.
Trees filter chemicals and other pollutants from water and soil.
Trees intercept rainfall, which protects against flash flooding and recharges groundwater supplies.
Trees need less water than lawns, and the moisture they release into the air can significantly reduce the water requirements of other landscape plants.
Trees conserve energy, making our buildings, systems, and properties more efficient.
Trees mitigate urban heat island effects by providing shading.
Trees provide shade, moisture and windbreaks, decreasing the amount of energy needed to cool and heat our homes and offices.
Trees improve mental and physical health for people at every age.
Trees create a desirable environment for outdoor physical activity and encourage active lifestyles.
Trees reduce symptoms or incidence of attention deficit and hypertension disorder (ADHD), asthma, and stress.
Trees reduce exposure to UV radiation, thus reducing the risk of skin cancer.
Tree views can speed the recovery time for patients recovering from medical procedures.
Trees produce fruit and nuts to contribute to healthy diets.
Trees create a setting for neighbors to interact, strengthen social ties and create more peaceful and less violent communities.
Trees contribute to the overall physical, mental, and social well-being of individuals and communities.

Trees create employment opportunities for people to start, develop, and succeed in their careers — making California’s cities and towns better places to live, work, and play.
- There are more than 50 million sites available for planting new trees and approximately 180 million trees in need of care in California’s cities and towns. With plenty of work to be done, California can continue job creation and economic growth by investing in urban and community forests today.
- Urban forestry projects provide critical training to young adults and at-risk youth along with opportunities in the public works sector. Additionally, urban forestry care and management create both public and private sector jobs while also creating a healthier, cleaner, and more livable environment for decades to come.
- See the economic value of trees on CAL FIRE’s Urban Forestry Economic Impacts Fact Sheet.

“Urban Forests are critical to changing the quality of environmental health in our communities; our approach promotes restoration and environmental stewardship.” — Kemba Shakur, Urban ReLeaf Executive Director
“We are taking youth that are on the fringe of being employable, at-risk youth, and giving them training. At the same time they are required to complete their diploma, which makes them competitive in the job market.” — Nathan Higgins, CSET Project Manager
Trees make our communities safer, more valuable, and more fun to be a part of.
Tree planting, care and management generate jobs in both the public and private sectors.
Trees can increase the value of residential property by 10% or more.
Trees can boost business and tourism in commercial areas by providing shadier and more inviting walkways and parking lots.
Trees attract new businesses and residents.
Trees cut costs for heating and cooling and landscape water.
Trees are powerful and do so much for our families, neighborhoods, and the world.
