Hemlock Woolly Adlegid 

Did you know that winter is the best time to survey for Hemlock Woolly Adelgid (HWA)? This tiny insect is a big problem for our forests and water resources in the Northeast. We need your help monitoring the spread of this invasive species!

HWA Winter Mapping Challenge 

Feb 12 - March 13, 2022

From Feb 12 - March 13, 2022, we got more than double the amount of reports compared to 2021 during the same period!

In particular, volunteers conducted extensive mapping in early detection regions (SLELO and the Northern Adirondacks), and along the leading edge in the Lake George region, Central NY, and Western NY.

Honorable mention goes to several volunteers who reported across multiple counties and/or led group mapping efforts in their local communities.

Thank you.
