A major focus of the UC Cooperative Extension (UCCE) Master Gardener program in San Bernardino County is the “Trees for Tomorrow” project in partnership with the Inland Empire Resource Conservation District and over 30 other community-based partners and agencies. Over the past three years, over 1,200 climate-resilient trees have been
Why is this project so important? California has the lowest per capita tree canopy cover in the United States, a mere 108 square feet, disproportionally impacting people of color. Many neighborhoods in both San Bernardino County have tree canopy cover far below the recommended 25% - 40%, directly linked to extreme heat, high ozone concentrations, and high rates of cardiovascular and pulmonary diseases. A major reason for this low canopy cover is the result of fewer trees being planted in disadvantaged communities with low tax bases than in others. Another major reason is due to poor tree species selection and long-term maintenance, resulting in fewer than 40% of urban trees, on average, living beyond 20 years.
An important aspect of the project is its strong bilingual educational component that includes written tree planting and care information and in-person presentations describing the attributes of the climate-resilient tree species offered and tree care tips. Both help ensure that trees reach maturity, maximizing their ecosystem and social benefits. Another key

UC Cooperative Extension (UCCE) Master Gardeners of San Bernardino County are partnering with UCCE Area Environmental Horticulture Advisor Janet Hartin, the Chino Basin Water Conservation District (CBWCD), the United States Forest Service, and Mountain States Wholesale Nursery on two 'climate-ready landscape trees' studies. The goal of the projects is to identify tree species that will remain healthy under drought and higher temperatures in the greater Los Angeles basin. Twelve tree species that are native or non-native but adaptable to California conditions were selected for the study at UC Riverside (top photo) due to their expected potential to mitigate impacts of climate change. In addition, the potential ability of a four-inch layer of organic mulch to reduce soil evaporation and weed growth is being assessed on four of the twelve species in a second study at CBWCD in Montclair (bottom photo). Species included are Parkinsonia x Desert Museum (Desert Museum Palo Verde), Prosopis glandulosa 'Maverick' (Maverick Mesquite), Chilopsis lineris 'Bubba' (Desert Willow) and Pistacia 'Red Push' (Red Push Pistache). Trees were planted in late 2016 and received adequate irrigation for one year to assure adequate early growth. Irrigation was tapered off in 2017 and trees now receive no supplemental irrigation. The first round of results will be reported in December, 2019. Nine UCCE Master Gardeners are assisting in the CBWCD research project (bottom photo).
