WARRENSBURG — The hemlock wooly adelgid is an invasive aphid-like insect that has been wreaking havoc on hemlock trees and has been spotted in Warren County. To help educate people and thus protect trees, Charlotte Malmborg of the New York State Hemlock Initiative at Cornell University will present a workshop at 10 a.m. Saturday, Dec. 16 at the Warrensburg office of the state Department of Environmental Conservation, 232 Golf Course Road.

The workshop will be an hour-and-a-half informational presentation and then a one-hour field portion. Malmborg’s presentation will feature the most up-to-date knowledge about the adelgid, including the work of Mark Whitmore.
