I'm sure there can be some localized tree damage from nest weight and high nitrogen feces accumulation, but there have been high density heron rookeries on Chimon and other Norwalk Islands off and on since at least the 60's and the last time I looked (last summer) there were still plenty of trees. I would guess that invasives like ailanthus, bittersweet, etc have a far greater impact over the long term. Heron rookeries tend to move around so the important thing is to maintain a collection of suitable sites that can rejuvenate and provide nesting habitat to go with the salt marsh feeding habitat that remains.
