Floristic Quality Assessment - Coefficient of Conservatism

Coefficient of Conservatism (CoC) values are the key component of the Floristic Quality Index, a tool used to assess the quality of natural communities. CoC values range from 0 to 10 and are based on two factors: 1) plants have various degrees of fidelity to specific habitats and their quality, and 2) plants have varying tolerances to disturbances and respond in various degrees. These are provided for the three EPA Level III Ecoregions in Maine.

Comments or questions regarding CoC values for Maine or the list should be directed to Don Cameron (don.s.cameron@maine.gov).
