Floristic Quality Assessment
• What is it?Floristic Quality Assessment (FQA) is a tool to assist environmental consultants, scientists, natural resource managers, land stewards, environmental decision-makers, and restorationists in assessing the floristic, and implicitly, natural significance of any given area throughout Michigan. It is intended to be a simple, consistent, and repeatable method for
evaluating the relative significance of tracts of land in terms of their native floristic composition.
