Attend our training to become an Invasive Shot Hole Borer Monitor in Los Angeles and Orange Counties

November 17 & 19, 2020

Invasive shot hole borers (ISHB) are invasive wood boring beetles that attack numerous native and non-native trees in Southern California. These beetles mechanically damage trees by boring galleries/caves into trunks and branches and carry a fungal disease called Fusarium Dieback. This fungus is “farmed” by the beetles as food and supports their reproduction.

This is concerning because trees that become infected with this fungal disease are prone to branch dieback, canopy loss, and mortality. Once infected, mortality can quickly occur within 1-5 years. Infested trees become sources of beetles that can spread to the neighboring areas. This  rate of spread can be drastically increased by humans if infected wood gets moved out of the infected area. While this beetle/disease complex can affect hundreds of tree species in both urban and natural areas. In Southern California, drought has already weakened many trees and now they must also fight infestations!

How you can help: Knowing where beetles have spread will assist scientists and many other conservation agencies plan for management. Your participation is needed to detect early infestations in Los Angeles and Orange Counties.

Training for Monitors: Those in close proximity to Los Angeles and/or Orange counties can become trained monitors by scientists from UC Cooperative Extension. California Naturalists, Project Learning Tree Educators, and Master Gardeners are especially encouraged to attend.

Dates: November 17 from 10:00 - 11:00 AM, and November 19 from 10:00 AM - 12:00 PM.

Location: Virtual Zoom meeting. The meeting access information will be sent to registrants prior to November 17.

Cost: Free.

Training Requirements: To receive the full training,

  • Attendance at both days is required.
  • Completion of the 1 hour online eXtension Shot Hole Borer training is required before November 17.
  • Monitors must create or already have an account on iNaturalist.
  • Monitors must upload at least 1 observation to iNaturalist using the correct protocols.

Registration: Please complete the survey here

Training Agenda:

Pre-Session 1 Assignments:
Completion of the 1 hour online eXtension Shot Hole Borer training.
Create an iNaturalist account.

Session 1, Nov 17  (10:00 - 11:00 AM):
Speakers will cover how this project fits into the big picture of efforts to manage emerging tree pests in California. There will be a short review of ISHB identification, and then an overview of how to use iNaturalist for this project.

Pre-Session 2 Assignment:
Upload at least 1 observation to iNaturalist using the correct protocols.

Session 2, Nov 19 (10:00 AM - 12:00 PM):
Speakers will review ISHB symptoms and iNaturalist collection protocols; look-alikes and tree species identification; troubleshooting based on their experiences with the homework.
