California has a goal of increasing urban tree canopy cover by 10% by 2035 (per California AB 2251: Urban Forestry: Statewide Strategic Plan). However, an open source, reliable dataset with multiple years of high resolution canopy cover maps has not been created at the statewide scale.

This webmap shows urban tree canopy in California, along with population and environmental characteristics that can help identify communities disproportionately burdened by risks that urban tree cover may help ameliorate.
California’s urban tree canopy covers 15% of the urban areas and contains an estimated 173 million trees. The annual value of ecosystem services from these trees has been estimated at $8.3. billion and the urban forest asset has been valued at $181 billion (McPherson, E., et al 2017).The tree canopy layer was created by EarthDefine, LLC ...
Urban Tree Canopy assessments allow communities to prioritize planting/greening goals based on social, economic, and ecological criteria such as flooding, wildlife habitat, urban heat island/heat stress, public health (e.g., asthma), crime, income, and other variables. The information from these assessments has been used to inform UTC goals ...
Jul 20, 2023 · By sharing their suite of tools and data with others, the USC Dornsife researchers offer others a playbook to increase their urban tree canopy while respecting environmental justice goals. “Tools like ours combined with a strong community voice and advocacy can help people make a case for policies and funds necessary to make a difference in their neighborhoods,” Pastor says.
One of those tools — the urban tree canopy viewer — can help inform how organizations plan their urban forestry projects. These open-source, interactive maps of Hawai'i and California were developed by the Forest Service and state urban forestry programs with data from the census and national weather service.

An Urban Tree Canopy (UTC) assessment, which provides a measure of a community's tree canopy cover, is important for understanding the extent of a community's forest or tree resource. UTC assessments are often used for establishing and implementing municipal tree canopy goals as part of broader urban greening and sustainability initiatives.
