Description

Invasive shothole borers (ISHB) are beetles that tunnel into trees and introduce a fungal disease (Fusarium dieback) that can cause tree death. Well established in many areas of Southern California and the Central Coast, the beetle-disease complex has killed thousands of trees. It continues to spread, threatening the integrity of California’s urban and riparian forests. 

Designed for land managers, arborists, and other professionals whose work includes tree health and/or pest management (as well as anyone seeking an in-depth understanding of the pest-disease complex), the 2023 Invasive Shothole Borers-Fusarium Dieback Symposium will take a deep dive into the current distribution, impacts and risks, best practices in control and management, and practical examples of successful management approaches.
