Floristic Quality Assessments (FQA) are an increasingly used tool in assessing the ecological integrity of natural areas in North America. Each species is assigned a coefficient of conservatism (C-value) on a scale of 0 to 10, which corresponds to its tolerance of anthropogenic disturbance and/or fidelity to a particular habitat. Species lists can be used to calculate mean C for a specific site and sites can be compared.

Is this tool or something similar used elsewhere in the world? Has anything analogous to it been used for taxa besides plants?
