Tree Insects and Diseases
Trees, like any living thing, are susceptible to disease and can be damaged by insects. Since our urban forest has many trees and a variety of species located close to each other, we all need to do our part to monitor for and stop the spread of tree insects and diseases.
Please visit the applicable pages to review the tree disease handouts and links to learn more about the Integrated Pest Management (IPM) techniques that can help you to eliminate these diseases.
