Join Douglas Cygan, Invasive Species Coordinator for the New Hampshire Department of Agriculture, for a deep dive into the upland invasive plants of New Hampshire. Learn how to identify some of the most aggressive non-native plants that can be found here in the Granite State, and how to control them. We’ll also discuss New Hampshire rules and regulations surrounding invasive plants.

7 to 8:30 p.m. at the Harris Center. Space is limited, and registration is required. For more information, including questions about accessibility, contact Eric Masterson.
