% Area OccPercent Area Occupied simply is the percent of 20x20 km cells within the total area of the eastern United States that have been modeled to be suitable for the species.
Ave IVAve. IV is the average importance value across all 20x20 km cells that have been modeled to be suitable for the species.
Sum IVSum IV is the sum of importance values across all cells. Thus it is a metric that considers both the abundance and the range of the species, perhaps the best metric of overall species importance.
Future/Current IVFuture/Current IV is the ratio of change between the modeled current Sum IV and any of the GCM scenarios Sum IV.

Interpretation GuideView the guide to reading the interpretive narrations
Mountain or Frazier magnolia is a very narrowly distributed (0.7% of area), sparse, and low IV species rarely found in southern Appalachians. We were not able to model it.
