UC ANR program trains volunteers to accurately identify and report infested trees, protecting forests and encouraging civic engagement through participatory science.
The Issue
Invasive pests are one of the main threats to our urban and natural forests. Tiny beetles, like the invasive shothole borers (ISHB), attack trees and cause their decline and death. Even though ISHB can have devastating effects to urban and natural forests throughout Southern California, many trees can still be saved with proper management, allowing infested areas to recover over time. Detecting infestations early is key for successful management of this pest and to prevent spread to new areas.
Participatory science can be a useful tool to identify ISHB-infested trees and help monitor high-risk areas throughout the state. However, accurately identifying the presence of ISHB is challenging because the beetles spend most of their lives within the tree, hence we must rely on signs and symptoms to determine if the tree is infested (to learn more, visit www.ISHB.org)
How UC Delivers
Given these challenges, we wanted to know if participatory science can still be a good tool to monitor for ISHB. We created a training program to teach volunteers how to identify ISHB-infested trees and evaluated how different training modalities can make volunteer's observations more accurate.
UCCE Urban Forestry Advisor, Beatriz Nobua-Behrmann, teamed up with the California Naturalist program to develop a reporting tool in iNaturalist and a six-hour training that included an online course, two workshops, and after-training office hours for follow-up questions. They ran two trainings: one fully online in October 2020, and one that included an in-person component in October 2021. A total of 34 participants were trained, including volunteers from the California Naturalist and the Master Gardeners programs, and other community members.
Each participant reported up to five ISHB-infested trees. Each report included descriptive data of the individual tree, level of infestation, geolocation, and pictures of the signs and symptoms observed. To evaluate the accuracy, first UC experts assessed each report and determined if the tree was probably infested or not based on the submitted pictures. Then, UC experts located and re-assessed the same trees in the field. The data collected by the volunteers was compared side-to-side with the data collected by the experts to evaluate the accuracy of volunteer-collected data.
The Impact
Participants of this program learned how to identify and report ISHB-infested trees and the importance of early detection to successfully manage invasive pests. Despite the challenges of correctly identifying infested trees, participants applied what they learned by submitting more than 122 reports of suspected infestations. After experts re-assessed the reported trees, we learned that volunteers collected overall high-quality data, but training modality seemed to make a substantial difference in the accuracy of the IDs. Volunteers who received in-person training were significantly more accurate (96% correct ISHB IDs) than the ones who received online training only (85% correct IDs).
Many program participants are now participating in the Master Gardeners Emerging Tree Pests Program and are sharing this information with the public, helping to create awareness in their community, demonstrating how UC ANR's civic engagement helps to protect California's natural resources.
All the incorrect IDs confirmed in the field were also previously flagged as possibly incorrect during the first evaluation of the reports from the pictures. This means that future quality control can safely rely on experts evaluating the pictures in the reports without having to re-evaluate the tree in person. Thanks to this study, we now know that community-based data can reliably contribute to the local and state-wide efforts to monitor the presence of ISHB, especially if in-person components are included in the trainings. Future steps of this program include delivering more trainings and using the data collected by the volunteers to inform the current ISHB distribution map available to the public. Having accurate information on the current distribution of ISHB throughout the state is an important decision-making tool for the agencies working on managing this pest, who need to determine where the infestation focuses are and how far away they are from other high-risk areas.

CFHL, UC partners with San Mateo and Santa Clara county schools to increase structured and non-competitive physical activity opportunities for school-aged youth through the CATCH curriculum, contributing to improved community health and wellness.
The Issue
Since students returned to school and in-person learning, school administration witnessed a decline in student's social skills and physical activity abilities from previous years. Principals and teachers expressed concern that anti-social behavior was prevalent and believed it was a result of the isolation caused by the COVID-19 pandemic. One principal in Santa Clara County shared an observation that “students were having a difficult time making friends” and “many students would spend time by themselves, rather than engage with classmates.” School staff also noted that students were not getting the recommended 60 minutes of daily play during the pandemic.
In Spring 2022, CFHL, UCCE educators supported schools as they were dealing with low school staffing levels and students struggling to re-enter the classroom. Re-learning some of the skills associated with interacting and socializing, and then ramping up physical activity in the post-pandemic world was needed.
How UC Delivers
After hearing about the challenges facing schools, CFHL, UCCE developed an active recess program to help schools address supervision and staffing issues while engaging students in physical activity. School administrators and teachers were excited about this program and hoped structured recess games would engage their students physically and help them learn to interact cooperatively.
CFHL, UCCE educators attended school recess regularly, on a once- or twice-a-week basis, bringing CATCH games with them. At some elementary schools, CFHL educators reached all of the students with their games, from kindergarten to 5th grade, and at some school sites, educators focused on providing activities to just Kindergarteners. Games helped build a range of skills, from locomotor skills and coordinating with others, to developing balance, catching, and hand-eye coordination skills.
In San Mateo and Santa Clara County, CFHL, UCCE educators supported recess CATCH games with an array of equipment, from hula hoops, beanbags, frisbees, polyspots, scarves, and more! Students were welcome to join in for games such as dragon's tail, fruit salad, scarf and bean bag toss. Students were welcome to use the supplies to enrich their own play and it was common to see students building castles with cones, and juggling. These games were welcomed by the students, from K-5, with cooperation, laughter, and the request that CFHL, UCCE educators come the next day to play some more! This feeling was expressed by the Sunshine Gardens Principal, who stated “I only wish they were here every day!"
The principal at Sunshine Gardens went further to say that the games “allowed students to build skills and confidence and set goals”. At Castlemont Elementary,the principal saw that “more students were actively engaged”, a sentiment that was echoed at Pescadero Elementary, where a school leader noted that students were much more active during recess after the implementation of the active recess project.
The Impact
CFHL, UCCE Educators collected active recess evaluations to document CATCH adoption across four sites, reaching 795 students. Principals across sites reflected that the games were more cooperative than competitive, which encouraged more participation. The principal at Bowers Elementary also liked that the games “were structured so that they helped develop cooperative skills”. Pescadero leadership saw CFHL, UCCE involvement as both helpful and important, and all four participating schools requested continuing active recess work in the 2022-23 school year.
Recess interventions have been shown to increase the amount of physical activity children get and when children regularly engage in physical activity, it can lead to improved cognition, fitness, heart health and mental health outcomes. Teachers and staff remarked on the value of CFHL, UCCE bringing physically and mentally engaging collaborative games and activities to their students. CFHL, UCCE educators are looking forward to the opportunity to continue supporting active recess in the 2022-23 school year. Educators and School sites are inspired to build on last year's success and there is a plan to provide CATCH trainings to teachers and staff to support additional physical activity policy, systems, and environmental changes in the new school year. In this way, CFHL UCCE programming contributes to UC ANR's public value of Healthy People and Communities.

Adapted IPM Model from former UC ANR faculty is offered in multiple languages leading to potential profit increases of $1.79 million.
The Issue
Numerous endemic and invasive pests threaten all kinds of crops, and the application of synthetic pesticides is the most common control option in many cases around the world. Frequent application of pesticides leads to pest resistance, secondary pest outbreaks, increased risk of environmental and human health, and negatively impact sustainable crop production efforts both in the short-term and long-term. Integrated pest management (IPM) is a concept of pest management in an ecologically sustainable manner. IPM has been promoted for decades, and many farms apply IPM practices to some extent. However, there are certain deficiencies in the understanding of IPM, its components, finding non-chemical management options, and exploiting cultural practices to improve crop health and yields. The traditional IPM model faces challenges because of its limitations for practical applications. There is a need to improve the understanding of growers, pest control advisors, and crop advisors in developing comprehensive crop care strategies using IPM principles, as well as revise the traditional IPM model to fit the modern production trends and consumer preferences.
How UC Delivers
Former UC ANR Cooperative Extension Advisor Dr. Surendra Dara conducted extensive research developing IPM solutions and promoting biological control options for small fruits and vegetables in California and provided advice for managing pests in nurseries, ornamental crops, urban landscapes as well. The ultimate goal is to improve IPM knowledge and implementation locally, regionally, nationally, and internationally. Based on his decades of research and extension experience in the US and other countries around the world, Dr. Dara developed the new IPM paradigm in 2019 that incorporated social and economic aspects of crop production in addition to various pest management options and other influencing factors. He had been invited by multiple groups to speak about IPM strategies in multiple crops and the new IPM model. Multiple symposia were organized at professional conferences, farmers, crop care professionals, and agricultural input industries updated their crop production and protection strategies based on the new IPM model. The model has been translated into multiple languages with international collaboration.
An anonymous online survey conducted between December 2021 and May 2022 received responses from California and elsewhere. Forty-five respondents from allover California, Arizona, Florida, Georgia, Hawaii, Indiana, Illinois, Michigan, Minnesota, North Carolina, Ohio, Oregon, South Carolina, Washington, and Wisconsin states in the US, and from Argentina, Australia, Ethiopia, Honduras, India, Kenya, Mexico, Mozambique, Nigeria, Pakistan, Portugal, Tanzania, and Uganda participated in the survey.
The Impact
Survey results showed that 95.6% found the information from Dr. Dara's IPM program was useful, and 93.3% people would use that information or have used it to improve their farming operations. The IPM information has been or would be used on 33,703 acres with a realized or expected savings or additional returns of $1.79 million. The respondents also indicated that they have or would share the information to 132,739 people. Survey respondents included farmers, pest control or crop advisors, private researchers, agricultural industry partners, and university faculty or researchers. Since it was published in the Journal of Integrated Pest Management in late April 2019, the new IPM model has been read or downloaded more than 48,000 times so far. Dr. Dara's research and extension demonstrates an ongoing commitment to UC ANR's public value of protecting natural resources in California and beyond.

After attending UC ANR's Science for Citrus Health webinars, over 50% of participating citrus professionals say they intend to adopt actions related to psyllid management. These practices can help safeguard abundant, healthy food for all Californians.
The Issue
Huanglongbing? Never heard of it? Why should I care? Maybe you need to learn more?
Huanglongbing, HLB, a bacterial disease of citrus also called Greening Disease, is spread by the Asian Citrus Psyllid. It causes the citrus fruits to be deformed and taste salty and bitter. HLB was first reported over a century ago in southern China. But why is it a problem for U.S. citrus? Diseases don't “respect” country borders and in 1998 the psyllid and the disease arrived in Florida in the early 2000's. Because there is no cure, damage caused in the largest orange producing state was extensive. By 2019, citrus production decreased in Florida by 74%. Despite federal bans on interstate movement of host plants, the psyllid did not abide by those rules!
And the disease also easily spreads from state to state. The first tree with HLB in California was found in 2012 in Los Angeles County. Then the question became, even though millions of research dollars were being spent, is there progress toward a cure? What could be done in California to slow the spread? Much was learned in Florida's battle and much is being learned through research. But it is hard for growers, the media, and the public to understand how that information might be used in California.
How UC Delivers
To address this information gap, Cooperative Extension Specialist Beth Grafton Cardwell and I started Science for Citrus Health (SCH) in 2015. It is designed to spread in lay language information about research aimed at understanding and combating HLB. SCH is now a cooperative effort with individuals from California, Florida and Texas, involving many activities.
These included developing Snapshots, short, two-page pieces on HLB research, written in lay language, posted on the SCH website, on Instagram, and disseminated at citrus meetings. In total, 45 Snapshots have been written, focusing on five themes related to detection, disease and psyllid management and the tools being used. Another resource for educational efforts is a large PowerPoint slide set, covering genetics, as well as regulatory and consumer issues. Recently efforts expanded, owing to grad students and postdocs, to include a YouTube channel on HLB and a popular podcast series that focuses on HLB researchers, their approaches and their career stories. Another effort involves translating citrus information and Snapshots into Spanish to reach Hispanic growers and workers in the citrus industry. In 2021, five informational webinars were convened on topics, such as ACP and HLB Management, the use of particle films to manage HLB, and citrus thrips. A recent webinar on the biology and management of ACP was presented in Spanish. These webinars attracted international audiences of up to 300 people.
The Impact
Post-meeting polls from UC ANR's Science for Citrus Health webinars indicated that more than 50% of attendees would implement at least one new practice they learned at the session. Research from the University of Florida has shown that the application of particle film screens, for example, has the potential to reduce ACP populations by more than 80% compared to monthly insecticide treatments, thereby contributing to UC ANR's public value of safeguarding abundant, healthy food for all Californians. Creation and proliferation of SCH efforts, providing information on research efforts focused on HLB, is an important educational resource for citrus growers, the media and industry. Another resource provides slides and educational materials to be used by educators for presentations to these groups, and the public. These newly created educational resources, some in Spanish, are unparalleled on other citrus sites.

Partnering to support nutrition incentive programs at farmers markets provides increased access to healthy food for CalFresh recipients and generated over $380,000 in revenue for local farms.
The Issue
For low-income community members, CalFresh/SNAP incentive programs can increase their purchasing power, help reduce hunger, and improve nutrition. Farmers market nutrition incentives provide economic benefits to local farmers and communities, reduce food miles traveled, and can increase access to healthy food in low-income communities. In San Luis Obispo County eight year-round farmers markets accept CalFresh and offer the market incentive Market Match. However, these programs are underutilized, and many low-income shoppers are unaware or uncertain about where and how to use their CalFresh card.
How UC Delivers
To increase access to farmers market incentive programs and address barriers, UC staff convened partners through the EBT at Farmers Markets working group of the San Luis Obispo Food System Coalition. The work group includes partners from multiple sectors, including agriculture, government, private industry, and community-based organizations. The purpose of the work group is to increase the use of CalFresh at farmers markets to 1) create equitable access to healthy food and 2) support for local farmers. Through this work group, partners have collaborated to increase the visibility of farmers market incentives through social media, text messaging, materials distribution to local client-serving organizations, press releases, paid advertisements, and promotion at local food bank distributions and farmers markets.
Key work group partner representatives (n=6) were surveyed in September 2021 using the Wilder Collaboration Factors Survey. This survey includes 44 evidence-based items for collaboratives. Strengths are indicated by an average score of 4.0 to 5.0, while areas needing attention are 3.9 or lower. Strengths reported by respondents included: skilled leadership (4.3), unique purpose (4.3), mutual respect and trust (4.4). Weaknesses and areas of growth included: adequate funds (2.7) and time (2.7), and having all the organizations that we need as members of the group (3.2).
To address some of the issues related to time and resources, the work group applied for and received $30,000 in funding from the Danone Foundation to pilot a Farmers Market Navigator program to increase access to farmers market incentives among Hispanic and Latino customers who use CalFresh.
The Impact
Since 2017, when UC started convening the EBT at Farmers Markets work group, we have seen a 171% increase in CalFresh and Market Match redemption. Research has shown that access to fruits and vegetables supports healthy eating behaviors and improved health outcomes. Additionally, these purchases have generated a total of $386,000 in direct income to local farmers and farmers markets.
In addition, the work group has supported two additional markets in launching their Market Match program and has advocated for and achieved a regional standard incentive amount of $15 from Paso Robles in northern San Luis Obispo County to Lompoc in northern Santa Barbara County. This regional standard simplifies communication to low-income clientele and ensures a meaningful and standardized food budget when clients shop at local farmers markets.
Increasing access to local fruits and vegetables supports UC ANR's public values of safeguarding abundant and healthy food for all Californians and promoting healthy people and communities.
Our favorite quote:
“This work group really helped our market to be accepted into the Market Match program. I think without the visibility and partnership that this work group provided, we would not have been considered for Market Match. So you all should really feel good about that and thank you.”
– Farmers market manager and work group partner
