Variable General Info
Floristic Quality Index (FQI) ?Comment:Using floral richness recorded in plots, we calculated Floristic Quality Index (FQI). FQI is a metric devised by botanists to assess the vegetative quality of a habitat. This metric combines the floral richness of the plot and the coefficient of conservatism (CC), and thus provides a rank‐based assessment of the sensitivity of a plant species to disturbance (on a scale of 1–10). FQI can provide important information on the overall conservation status of the habitat. Using the CC for each plant species as designated in Ladd and Thomas (2015) for Missouri or Taft et al. (1997) for Illinois when absent from the Missouri list, we calculated the FQI for each plot as FQI=mean CC∗√N where N is the native species richness and mean CC is the mean of the coefficient of conservatism. All invasive species were assigned a C of 0 and not included in the native species richness calculation as implemented by Maginel, Knapp, Kabrick, Olson, and Muzika (2016). FQI was designed to evaluate the entire plant community, but we only evaluated the flowering community. |
