Cornell Cooperative Extension of Columbia and Greene Counties will be hosting a general information and Phenology Monitoring Training workshop for the Hemlock Woolly Adelgid, an invasive insect threatening one of the most important tree species in the northeast. Presented by Charlotte Malmborg of the New York State Hemlock Initiative. Guests will learn about the threat this beetle poses for New York’s forests. The first part of the training will focus on identifying hemlock trees and hemlock woolly adelgid, management techniques for landowners and managers, and biocontrol opportunities. The second part involves phenology monitoring and a field component, so participants are encouraged to dress appropriately. Registration online or by calling 518-622-9820.
