The New Hampshire Shoreland Water Quality Protection Act was designed to preserve the benefits the waterbodies provide, they are the guidelines for waterfront property owners to follow. While tree pruning and removals are allowed, there are limits for what kind of work can be done and how many trees and plants need to remain. No tree can be removed from segment at or below the minimum points unless formally assessed to be a hazard by an arborist. Trees can be pruned as long as the health of the tree is not endangered.
