This paper describes our initial evaluation of survival and performance of 14 species of trees being tested in Southern California's Inland and Coastal communities as part of the statewide Climate-Ready Trees study. Overall, 88% of all trees survived the first three years and survival rates for trees in reference sites (95%) were greater than for trees in parks (84%). Survival rates were higher in the Inland parks where growing conditions more closely matched the arid environments from which many of these species originated. Differences in species' survival rates and performance are presented and discussed.
