Invasive mapping using EDDMapS, Early Detection and Distribution Mapping System.
Taxonomy, descriptions, images, and distribution maps of invasive species for all of North America, with the ability for users to report sightings of invasive species.
Each New England state has a different list of invasive plants, both prohibited species and potentially invasive watchlist species.
The Buckthorn Blaster uses the cut-stump method of invasive plant chemical control, a simple and effective treatment option to stop invasive plant
growth.
The advantages of cut-stump treatment include:
-
A very low risk of non-target chemical damage that you have with spray application.
-
Up to 100% effective against invasive plant survival and regrowth.
-
Less expense and much more efficient compared to other control options.
Originally from Asia, Hemlock Woolly Adelgid (HWA) was first discovered in New Hampshire in Portsmouth in 2000. This small, wingless insect uses its piercing mouth-parts to feed in the xylem of
the small hemlock twigs. HWA, left untreated, can kill a tree in 4 to 10 years. We found HWA in our forests at Distant Hill during a logging cut during the winter of 2025.
Below are a few resources about Hemlock Wooly Adelgid and the Best Management Practices to control its spread:
