Floristic Quality Assessment (FQA)

The Chicago Region Floristic Quality Assessment (FQA) Calculator has been updated with the C values, taxa, and nomenclature found in Wilhelm & Rericha's Flora of the Chicago Region and continues to use the most up-to-date nomenclature and wetland indicator status ratings of the National Wetland Plant List (NWPL). The Chicago Region FQA Calculator also includes all upland taxa found within the Chicago Region following Robert H. Mohlenbrock's most recently published 2014 Vascular Flora of Illinois and integrates Swink & Wilhelm's 1994 Plants of the Chicago Region nomenclature as synonyms to the NWPL allowing users to enter acronyms for either old or new plant names. This allows the user to create reports for inventory and transect assessments with the most up-to-date nomenclature and wetland indicator status ratings following the NWPL. 

The Chicago Region FQA Calculator was reviewed and tested by the National Ecosystem Restoration Planning Center of Expertise and is now approved for use by the US Army Corps of Engineers. In future versions, flora of the states of Michigan, Indiana, Illinois and Wisconsin may also be added. Once a region is selected, their specific floristic information will be used to calculate metrics of the FQA. The FQA Calculator is free for download and will be updated regularly.
