Attend our training to become an invasive shothole borer monitor!

*Results from March 2023 ISHB Monitors Training*

Invasive shothole borers (ISHB) are wood boring beetles that attack many native and non-native trees in Southern California. These beetles bore tunnels into trunks and branches where they grow a fungus they use as food. The fungus causes a disease called Fusarium Dieback. Trees infected with Fusarium Dieback show branch dieback, canopy loss, and may eventually die. Infested trees become sources of beetles that can spread to surrounding hosts. This pest can also spread long distances through infested green waste and firewood, affecting new areas.

How you can help: Get trained, become an ISHB Monitor, and help us gather infestation data! In previous editions of the program, we learned that trained volunteers can identify ISHB-infested trees with 96% accuracy. This high accuracy of volunteer observations allows us to include the data collected through this program directly into the ISHB statewide distribution map. Knowing where beetles have spread will assist scientists, municipalities, and many other conservation agencies plan for management. Also, detecting infestations in their early stages allow for better chances of successful management. Your participation is needed to detect infestations throughout southern California.

Training for Monitors: You can become an ISHB monitor trained by scientists from UC Agriculture and Natural Resources. California Naturalists, Project Learning Tree Educators, and Master Gardeners are especially encouraged to attend, but curious minds of all ages are welcome.

Dates: Online training 7/7/2023. In person dates Ventura County 7/8/2023, Santa Barbara County 7/9/2023, San Diego County 7/14/2023, and Inland Empire (Riverside County or San Bernardino County) 7/15/2023 (specific locations to be determined).

Cost: Free.

Training Requirements:
