KEY FINDINGS <br />16 1 CITY OF PLEASANTON URBAN FOREST MASTER PLAN <br />Increasing Species <br />Diversity with Climate <br />Adapted Trees Will Help <br />Create a More Resilient <br />Urban Forest <br />The City's inventory currently contains 23,722 individual <br />trees, comprised of 114 genera, and 250 species. Of the <br />total 250 species, 36 species making up 11,132 trees, or <br />40.2% of the total City inventory, are likely to be poorly <br />adapted to Pleasanton's future climate if temperatures <br />continue to rise as predicted by California's Fourth <br />Climate Change Assessment (Cayan 2018). Species <br />predicted to be poorly adapted include American <br />sycamore, coast redwood, and maple (Acer species) <br />which combined comprise 2,279 trees or 11.5% of the <br />City's inventory and typically need higher levels of water <br />and cooler temperatures to thrive. California is continually <br />adapting to changing climate conditions with policies <br />that restrict water use and require the removal of non- <br />functional turf. These changes in statewide policy may <br />make it difficult for the City to supply the supplemental <br />
