NHEC Herbicide and Stump Treatment

There are some situations where mechanical control is unsafe, or will cause more unnecessary damage. In these situations a selective herbicide treatment is used to maintain the right-of-way.   Prior to applying a selective herbicide we seek permission from the landowner.

Another important tool is selective stump treatment. This treatment involves applying a small amount of herbicide to the stump of a recently cut hardwood tree.. This prevents the root system of the recently cut tree from producing multiple re-sprouts that will regrow and make the right of way vegetation thicker with undesirable tall growing species.

These applications are done to specifically target only the tree species that can grow tall enough to interfere with the wires. By removing these tall growing species, we encourage the low growing species to become established. Once established, these low-growers will out-compete the taller growing species by taking up growing space.  This means there will be less trimming to the right-of-way during the next vegetation maintenance cycle, as there will be fewer tall growing trees to cut or treat.

This practice also benefits wildlife. Areas comprised of diverse shrubs are host to more wildlife species, and provide more opportunity for pollinators who get food from flowering shrubs that are not targeted by the treatment. These treatments keep overall maintenance costs lower. Through this process we are promoting the growth of desirable species by minimizing competition from tree species.

We invite you to learn more about our treatment process by reviewing this fact sheet. If you are notified about an herbicide application at your property and have concerns, please contact Vegetation Control Service (VCS)  at 603-325-3227. VCS will address any issues that you have about an herbicide application on your property. Our members have the right to refuse the application of herbicides on their property and NHEC respects that right.
