How is vegetation in the rights-of-way typically maintained?
Most of the vegetation in PSNH rights-of-way is maintained through mechanical cutting. A 14-ton excavator with a hydraulic arm and a rotating drum is used to grind up trees and shrubs. Manual cutting with chain saws has also been used to a lesser degree, and herbicides were used a number of years ago but have not been used recently. Each right-of-way area is currently cleared about once every five years.
