Hemlock Woolly Adelgid

Research Questions: Where is hemlock woolly adelgid now, and where might it spread next? Is climate change affecting how hemlock woolly adelgid spreads?

Why this matters

Hemlock woolly adelgid is devastating eastern hemlock populations across the Gulf of Maine watershed. We need more data to figure out where it is now so we can prevent it from spreading further.

Hemlock Woolly Adelgid

Hemlock wooly adelgid is a small insect that drains sap from hemlock branches until the tree dies. Until recently, cold winters have limited the spread of hemlock woolly adelgid. As winter temperatures warm, scientists suspect this pest could spread throughout our region. We need your help to track this deadly pest. Join our project by monitoring your local forest for hemlock woolly adelgid and reporting what you find.

Contribute data any time of year. Try to check at least 10 branches on 10 trees before reporting your results.
