The NHESP has prepared fact sheets for named types of natural communities to go with the 2016 revision of the Classification of Natural Communities of Massachusetts, Version 2.0.  The formal and technical descriptions of the community types are in the Classification.

The Key to the Natural Communities described in the Classification of Natural Communities of Massachusetts, Version 2.0  pdf format of The Key to the Natural Communities

Keys to the descriptions of the natural communities of Massachusetts are intended to assist users in identifying the natural communities that they encounter in the state. As with the classification, the keys are intended to be used by anyone with an interest in conservation and a familiarity with the plants of Massachusetts. The keys lead to named natural community types, which are illustrated in fact sheets describing the natural community in more detail than available in the key.
