The Plum Island Sound estuary in northeastern Massachusetts is an ecosystem that is at once both hardy and fragile. The estuary is part of the Plum Island Ecosystems LTER; LTER stands for "Long Term Ecological Research." The LTER Network was created by the National Science Foundation (NSF) in 1980 to conduct research on ecological issues that can last decades and span huge geographical areas.
