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.
