Dichotomous Key

This tool will allow you to determine the identity of a coniferous species by making a series of binary decisions to narrow down the field of possible candidates until only the desired species remains.

Please note that this key is not comprehensive for Eastern Massachusettes, the Northeastern United States, or any other geographic region. The species included in the key are only those species covered by this field guide. This key is provided solely as an aid to identifying common conifers and should not be considered authoritative. Another source should be consulted if more reliable identification is required.
