FAIRHAVEN — As tree warden for the town, G. Bourne Knowles, among other responsibilities, removes diseased and damaged trees, or any trees deemed hazardous to the public way. In a coastal New England town with erratic weather, such as Fairhaven, it’s a busy job with plenty of people calling him throughout the week. “It comes down to they see a tree in front of their house, and I have to see trees in front of everyone’s homes. They have a localized problem. Depending on what the issue is, it may be something I wouldn’t classify as a hazard. Things take precedence over other things,” said Knowles.
