New York State Hemlock Initiative

Keeping the legacy alive

Welcome To NYSHI

The New York State Hemlock Initiative (NYSHI) is a Cornell University project that researches biological control solutions for hemlock woolly adelgid (HWA), and works with scientists, natural resources professionals, and New York residents that are united in their love for hemlock trees and dedication to hemlock conservation.

Our Mission

The New York State Hemlock Initiative (NYSHI) coordinates state-wide efforts of land owners, state and federal agencies, government officials, and concerned citizens to conserve New York State’s hemlock trees. Our research focuses on the management of hemlock woolly adelgid (HWA), a non-native invasive insect, including development of biocontrol options. Additionally, our work involves public outreach to engage stakeholders and increase awareness of the threats posed by HWA and other invasive forest pests.

What do you want to do?

Start here to learn all about hemlock trees and hemlock woolly adelgid. You’ll find resources ranging from biology to identification to conservation research happening right here in New York State. 

 We are supported by community scientists all over New York who help us find HWA-infested hemlock stands, assess tree health, and understand the timing of important HWA life stages. Check out our opportunities to get involved.
