To date, over 1,800 climate-ready shade trees and tips on their planting and long-term care have been provided by UC Master Gardeners and over 20 partners to residents of low shade neighborhoods in San Bernardino and Riverside Counties through the “Trees for Tomorrow Start Today” project. Tree species given away are identified from research projects including the joint University of California/United States Forest Service (USFS) study at UC Riverside as well as from other research, local observations, and input from the green industry and academic colleagues.
Why is this project so important? 95% of Californians now reside in cities and suburban environments. Resulting urban heat islands created by built environments coupled with impacts of climate change can be mitigated through nature-based solutions. Planting climate-ready shade trees now will help ensure cooler urban areas in the next several decades as trees mature and maximize their urban ecosystem benefits. Fortunately, the shade from a single well-placed tree can decrease surface temperatures of black asphalt and artificial turf by more than 70 degrees F in hot inland and desert cities. Studies show that surrounding air temperatures can also be reduced through the transpiration process.
A major goal of the"Trees for Tomorrow Start Today" project is to enhance tree canopy cover in low shade neighborhoods also plagued with much higher than average levels of air pollution and pulmonary and cardiovascular disease incidence. Events over the past month have occurred in Fontana, San Bernardino, and the Salton Sea.

Community nutrition and health advisor builds bridges across cultures in Tulare, Kings, Fresno and Madera counties
At a young age, Irene Padasas – UC Cooperative Extension community nutrition and health advisor for Tulare, Kings, Fresno and Madera counties – saw first-hand how environmental health conditions can impact a family's choices.
When she was in fourth grade, her parents moved their family from bustling Manila, capital of the Philippines, to a small town on a distant island. Her younger brother, who had been hospitalized at age 3 for a year due to complications from meningitis, had to re-learn how to walk and talk.
Padasas' mother hoped that leaving the more polluted urban environment would benefit his long road of rehabilitation. “The decision was made to ensure a better quality of life for my brother,” Padasas said. “So my parents decided to just move to the countryside.”
The family settled in a beach town in largely rural Aklan province, near the center of the Philippine archipelago.
“There are advantages living in a place like that, where you're close to nature; there's not much traffic; the community is very tight,” Padasas said. “You feel like you're part of this small community where everybody is looking after each other.”
Contributing to that sense of community – and cultivating close relationships to ensure the health and well-being of all – are just some of the reasons why Padasas chose her line of work in Cooperative Extension.
Padasas oversees the delivery of two federal nutrition programs in her region – CalFresh Healthy Living, University of California and the Expanded Food and Nutrition Education Program. She develops, provides and evaluates Extension programs in partnership with the diverse populations of the Central Valley, including a variety of Latino, Mexican Indigenous and Asian communities.
Despite differences in culture and background, Padasas works to find common ground and build bridges – often through a joke and a laugh.
“Humor is such a big part of Filipino culture; with the challenges that I encountered in life, humor was so important in getting through and bouncing back,” she said. “That part of my culture is an important aspect of me to build relationships and genuine connections and introduce the work that we do; they don't see us as a ‘researcher from University of California,' they see us just like them, just like anybody else in the community.”
Growing up near both the beach and farmland in Aklan, Padasas feels an affinity for the agricultural landscapes and lifestyles in the San Joaquin Valley. She remembers feeding her family's chickens and pigs and playing among the neighbors' cows and water buffalo.
“I feel like whenever I drive to different places here in the Central Valley, it reminds me a lot of my childhood back in the day,” she said.
Nevertheless, Padasas misses the food in the Philippines – especially the seafood that she grew up eating, succulent prawns and enormous fish found nowhere in California.
“We would wait by the shore for whatever the fishermen would sell – it's really fresh fish, literally fresh from the boat,” she recalled.
Mealtimes were central in the childhood of Padasas and her siblings, who both live in the Philippines and help care for their parents; her brother is an engineer and her older sister is a teacher. Food was and remains a focal point for sharing and connecting, within their household and across the culture.
“When I was growing up, my parents made sure we were spending time as a family, eating together during dinner and sharing special meals on weekends,” Padasas said.
Chance encounter leads to an Extension career
Padasas returned to the Manila metro area for college, at the University of the Philippines Dilliman, where she earned a bachelor's degree in special education. After working as a special ed teacher for about seven years, she went to graduate school at Ateneo de Manila University for her master's in developmental psychology.
Originally intending to pursue a career as a child psychologist, Padasas said her path changed when she met Maria de Guzman, a University of Nebraska professor and Ateneo de Manila alumna, who returned to her alma mater to present her research on “yayas” – live-in caregivers for children in the Philippines.
Intrigued by that study, Padasas leaped at the opportunity to pursue a Ph.D. with de Guzman at Nebraska, where she would write her doctoral dissertation on social capital – such as personal relationships and networks – as predictors of college success for underrepresented minority students.
It was also de Guzman, herself an Extension specialist, who guided Padasas on that career track.
“I knew at that time I wanted to work in Extension, but it was a vague concept to me because in the Philippines we don't have Extension as part of the university,” Padasas explained. “Dr. de Guzman was the one who really introduced me to Extension.”
During graduate school in Nebraska, Padasas gained valuable experience working with a diverse range of ethnic minorities and refugees, including Latinos, Filipinos, Yazidis and Congolese. She especially enjoyed working with children and teens – a favorite aspect of her work that continues to this day. Padasas said that, when given the opportunity to discuss her academic background, she mentions her educational experience to young people.
“I always make sure to talk about my work as a research scientist – to encourage these kids, especially those from underrepresented minority groups, to see themselves in my shoes, to show them that: ‘You could also become like me, a person of color, a researcher, and that's not an impossible path for you,'” Padasas said.
That academic track – and her entire life's journey – have prepared Padasas well for her current role, within an organization that spans the state of California and all its diverse communities.
“I think that's the beauty of the work that we do at UC ANR,” she said. “We are provided with so many opportunities to connect and to create impact for so many people across different populations.”

Welcome to Fall!
It's my favorite season and likely for many of you, as well. Beyond the holidays and extra time with family and friends, nature radiates its beautiful hues. In addition to lovely foliage, deciduous trees often expose exquisitely shaped and sturdy trunks. And, of course, there is the lovely fall foliage showcased by many species.
Did you ever wonder why trees "turn" color in the fall? The short answer: It's primarily a function of long, cool fall nights and short, sunny days. The longer answer? Chlorophyll is responsible for the basic green color of leaves we see in spring and summer and is a necessary component of photosynthesis, which uses sunlight to manufacture sugar (food) that is stored during the dormant period of the year. Carotenoids produce yellow, orange and even brown pigments in crops such as carrots, squash, bananas and many ornamental plants such as daffodils and poppies. Anthocyanins are red and orange in color and are most linked to lavish displays of brilliant fall foliage. They also give rise to coloring of strawberries, plums and cherries.
Here's the kicker: While chlorophyll and carotenoids are present in leaf cell chloroplasts throughout the entire growing season, during fall chlorophyll begins to break down. Voila! The lovely yellow and orange hues we all look forward to seeing are finally exposed. In addition, red hues (called anthocyanins) are produced in fall. So, in reality foliage doesn't "turn" orange or red at all.
Interestingly, the actual timing of color change varies across species and appears to be genetically inherited. The same species will exhibit a similar color scheme in cool temperatures in higher elevations at nearly the same time as it does in warmer lower elevation climates.
The intensity of color can vary quite a bit however. Where do temperatures enter the picture? Both the amount of color and the overall intensity of fall color is very linked to weather conditions that occur prior to and during the actual time the chlorophyll in leaves winds down. The most brilliant displays occur after several warm, sunny days and cool, crisp (above freezing) nights. This is because although lots of sugars are made in leaves during sunny daytime hours, the corresponding cool nights prevent the sugars from moving out. The amount of soil moisture also helps ensure that from year to year fall colors vary even in the same trees. So, either a late spring or a prolonged drought can both delay the display of fall color by a few days or even a few weeks.
What's the recipe for the most brilliant fall display? Most likely a warm, moist spring followed by a warm summer and sunny fall with cool autumn nights. Although fall color is not nearly as spectacular in lower elevations of Southern California compared to other colder areas of the nation, the liquidambar or American sweet gum (Liquidambar styraciflua) offers some pretty impressive fall color and an impressive 300 to 400-year life span. (Did you know that liquidambar got its name because it at one time was a sought-after chewing gum for Native Americans?)
Two “climate-ready” tree species with lovely fall foliage that grow in both the west portion of the county and the desert are the ‘Keith Davey' Pistache, a large street and park tree sporting crimson to scarlet colored foliage and its relative, the ‘Red Push' Pistache, a hybrid between P. atlántica x P. integerrima) which has lovely red foliage as it emerges in Spring as well as Fall. Others include the Raywood Ash (Fraxinus oxycarpa 'Raywood') sporting a reddish-purple hue in the fall, and the ‘Sunburst' Locust (Gleditsia triacanthos var. inermis 'Sunburst') which offers a vivid display of fall color. Unfortunately, it is susceptible to the Invasive Shot-Hole Borer. If you have one of these lovely trees already, take good care of it to help it stand up to this aggressive pest!
Happy Fall! Enjoy the cooler weather, family and friends, and lovely trees!

UC Cooperative Extension team in Sutter and Yuba counties showcases UC ANR programs, community partners
When dozens of elementary schoolers gathered to watch a live calf birth at Tollcrest Dairy in Yuba County, their comments ranged from “disgusting but cool” to “I saw something that maybe I'm too young to see.”
Expanding horizons, growing knowledge and gently pushing some limits were at the heart of a four-week day camp, Ag-Venture, organized by the University of California Cooperative Extension office serving Sutter and Yuba counties.
Throughout July, more than 80 campers – ages 5 through 12 – explored agriculture and science topics through field trips across the region, hands-on activities and lively presentations by UCCE advisors, UC Master Gardeners, 4-H specialists, UC Master Food Preservers and CalFresh Healthy Living, UC educators. All these groups fall under the umbrella of UC Agriculture and Natural Resources.
A grant from The Center at Sierra Health Foundation funded this day camp for underserved youth focused on agriculture and natural resources – the first of its kind in the area. Exploring the themes of “Interesting Insects,” “Foods and Farms,” “Woods and Water” and “Awesome Animals,” the campers learned directly from community experts and UC ANR scientists.
“Some of the kids might think scientists are only wearing lab coats and working with genetics and DNA and human-based science, but here they got to see agricultural scientists and natural scientists,” said Rayna Barden, the 4-H community education specialist who led the camp. “It was a cool way to showcase what ANR does and what we have to offer.”
Youth gain wide range of experiences, knowledge
Visits to local farms and ranches – with many chances to greet the animals – were a highlight for many of the camp participants.
“I liked learning about agriculture and the interactive activities,” said a fourth grader. “I saw a baby cow coming out of its mama, and they [farm staff] had to use a tool. It was cool.”
A sixth grader said: “I learned that feed is made up of everyday items, like almond shells and beer hops!”
“Sheep, cows and goats have one stomach and four chambers,” added another sixth grader.
That digestive tidbit was absorbed by the campers after a visit with UCCE livestock and natural resources advisor Dan Macon at Sierra Foothill Research and Extension Center, a facility operated by UC ANR in Browns Valley.
“We have 4-H kids and FFA kids in high school who still don't know how the four chambers work!” Barden said. “These kids had it and it was so cool to see that they remembered that from a previous day.”
Time and time again, Barden said she was amazed at how much the campers retained. After a visit to Bullards Bar Reservoir, a seven-year-old was able to explain why the dam is curved. Another young boy could draw his own interpretation of the water cycle. And several campers talked about the rice presentation for weeks.
Whitney Brim-DeForest, UCCE county director for Sutter and Yuba counties and a rice advisor, had the participants touch and feel different rice seeds and varieties. The campers also got to plant a few rice seeds to take home.
“But their favorite part – and what they talked about for the rest of camp – was the tadpole shrimp,” Brim-DeForest said. “We brought some live and preserved specimens, and they loved them!”
Sparking ideas for future careers
One third-grade camper said she enjoyed learning the differences between agricultural pests and beneficial insects.
“And you can do stuff to help the good bugs,” she said, adding that she would like to pursue a career working with animals and nature.
Expanding awareness among young people of new career possibilities was exciting for Ricky Satomi, UCCE forestry and natural resources advisor for Sutter and Yuba counties. Using interactive exercises (such as those developed by California Project Learning Tree, another UC ANR-affiliated program), Satomi shared his knowledge about resource competition, watershed filtration and fire behavior in forest ecosystems.
“It's always a pleasure to introduce students to the natural resources where they live,” Satomi said. “This is particularly critical given the current workforce shortage we face in forestry; I hope their experience at Ag-Venture will spark interest in future forestry careers, where these students can work to better their local forest communities.”
Young people from local colleges and universities also gained invaluable experience during the camp. Four students helped prepare the camp: Yasmeen Castro Guillen (Chico State), Alana Logie (Yuba College), Jayla Pollard (Folsom Lake College) and Adam Yandel (Chico State). Three more helped lead the camp as counselors: Hector Amezcua (Yuba College), Alyssa Nott (Butte College) and Jillian Ruiz (Chico State).
“They did such a fantastic job, mentoring the kids and serving as positive role models, and we have seen tremendous growth in all of them, too – in confidence, skills and knowledge,” said Brim-DeForest.
A true community effort
Barden emphasized that the sweeping scope and in-depth, intertwining lessons of the camp were only possible through broad support from the greater community. Brim-DeForest highlighted the partnership with Yuba City Unified School District, as well as with Sutter County. Camp HQ was in Ettl Hall, a Sutter County building; campers visited the Sutter County Museum; they also met Yuba-Sutter public health officer Dr. Phuong Luu.
Additional collaborators included Melissa Ussery, CalFresh Healthy Living, UC nutrition program supervisor; Rene McCrory, 4-H secretary; Johnny Yang, UC Master Gardener and Master Food Preserver program coordinator; Matt Rodriguez, 4-H youth development advisor; and Nicole Marshall-Wheeler, 4-H youth development advisor.
“Honestly, we could plan all of this, but without the community's support, our program never would have worked smoothly,” said Barden, who grew up in the small town of Sutter. “Having all of our guest speakers, having all the people who were willing to have up to 50 kids on their property – it just shows how much our community is about our youth.”
Brim-DeForest said Sandy Parker, the camp nurse, exemplifies that spirit. A UC Master Gardener and 4-H alumna and volunteer, Parker also invited the campers to her family ranch, where she introduced the children to her farm animals and Great Pyrenees guardian dog.
The campers certainly appreciated the generosity, teamwork and energy that went into Ag-Venture. Barden said that many of the participants originally had only signed up for one or two weeks – but loved the camp so much that they asked to register for more. And she added that the “vast majority” of them said they want Ag-Venture to come back and would attend in the future.
“Our youth are just so resilient and so willing to learn,” Barden said, reflecting on the camp overall. “Whereas adults, we're usually a little more timid at things, these kids just were willing to dive in, head first, and be in that moment and try to take away as much as they could from what they were offered there at camp.”
