Tree San Diego

Tree San Diego is a 50l(c)(3) tax-exempt organization addressing the significant deficit in the San Diego region’s tree canopy, thereby contributing to human and environmental health. We collaborate with governmental, non-profit, and private entities including ones that work for human and environmental sustainability and justice. Our mission is to significantly increase the number and impact of urban trees in San Diego County and beyond–by adding right trees, in right places, for right reasons, with right care, i.e., “Terrific Trees”.


Trees Planted


The tree canopy in the San Diego region is estimated to be 60 – 70% below what it should be for the health of both humans and the environment. The most concerning aspect is that the percentage of tree canopy may actually be decreasing, making a bad situation worse. There are many contributing factors, such as drought, tree disease, and human indifference and neglect. One factor has been the absence of a non-profit urban forestry organization dedicated to promoting the increase in the quantity of quality tree canopy in our region. All other major metropolitan areas in California have benefited from having one or more such non-profit organizations in place for decades. Tree San Diego was established to fill that void and will grow to be a strong force in reversing the trend in our tree canopy.
