SoCal Edison staff, bolstered with UCCE training, identify Goldspotted Oak Borer infestations and trigger swift response, demonstrating enhanced workforce capacity to combat invasive species and protect California's forests.
The Issue
Invasive tree pests pose a significant threat to California's urban and natural forests. Among them, the goldspotted oak borer (GSOB) has inflicted severe damage on the state's oak populations, resulting in substantial tree mortality and altering forest ecosystems. This invasive beetle primarily targets coast live oaks, California black oaks, and canyon live oaks. The decline of these iconic trees disrupts natural habitats and negatively impacts local economies that rely on healthy forests for recreation, tourism, and timber resources. As new infestations continue to rise in Los Angeles and Orange Counties, timely identification and management are crucial for safeguarding oak forests and their associated wildlife. There is an urgent need to both partner with those regularly inspecting trees and provide opportunities to enhance workforce competency in pest management.
How UC Delivers
To address this pressing issue, a collaborative team from University of California Cooperative Extension (UCCE) partnered with SoCal Edison (SCE) to organize a comprehensive four-hour training session in July 2024. This session brought together 57 participants, including staff and contractors from SCE, at the company's offices in Irwindale. Instructors included UCCE Advisors Beatriz Nobua-Behrmann and Chris Shogren, along with Joelene Tramm, the Natural Resources Director for the La Jolla Band of Indians and a master's student in Entomology at UC Riverside. Randall Oliver (UC Integrated Pest Management) and Julie Clark (UCCE Ventura County) provided logistical support to make this happen.
The training equipped participants with essential skills for identifying GSOB infestations, implementing effective management strategies, and preventing the pest's spread by properly disposing of infested plant material. It featured real-world examples of successful management practices and the latest research findings. In addition to GSOB, the agenda included training on identifying other critical tree pests and diseases. Participants engaged in interactive discussions, fostering a community of practice focused on protecting California's forests.
The Impact
The impact of this training was immediate and measurable. Within two months of the session, SCE staff reported two new suspected GSOB infestations in previously unknown locations. Armed with the knowledge gained from UCCE, they promptly initiated best management practices. Once our UCCE team was informed of these suspected infestations, we coordinated a collaborative response involving agencies such as CalFIRE, the Inland Empire Resource Conservation District, LA County Fire, and the US Forest Service. This swift action not only confirmed the new infestations but also established a solid foundation for strategic interventions.
Feedback from the training highlighted its effectiveness: 60% of attendees completed a post-training survey, with all respondents unanimously expressing increased confidence in identifying and managing tree pests and a commitment to applying their newly found knowledge. By empowering SCE staff and contractors with essential training, UC ANR has strengthened California's workforce competency and enhanced the state's capacity to combat invasive species and protect its natural resources.
Looking ahead, the collaboration between UCCE and SCE is set to continue, with plans for ongoing training sessions and resources to support pest detection efforts across Southern California. The success of this initiative underscores the importance of partnerships in addressing environmental challenges, providing a model for future interventions.
“Through UCCE training and SCE collaboration, we have been able to collectively expand inspection horizons throughout SCE utility corridors that has helped discover new distribution patterns”- Chul Paik, SCE Senior Specialist
In conclusion, through targeted training and collaborative action, UCCE is making significant strides in safeguarding California's natural resources while enhancing workforce competency in invasive species management. This proactive approach not only benefits the immediate environment but also fortifies the resilience of California's forests for generations to come.
