Activity Cards

The Invasive Shot Hole Borers (ISHB) are non-native beetles that tunnel into trees, introducing a fungal disease known as Fusarium dieback. This disease disrupts the tree’s ability to absorb water and nutrients, resulting in symptoms such as tree decline, branch dieback, and potential tree mortality. Join our ISHB monitoring efforts and help protect our Sycamores in the Arroyo Trabuco Wilderness Area.

During ISHB monitoring, participants will learn about the signs and symptoms of ISHB infestation in Sycamore trees and survey techniques. They will use specific data gathering applications to survey tree trunks for ISHB entry/exit holes, identify affected trees, and update the data collection form for each surveyed tree.
