This tool allows you to compare two species side-by-side. Select a species to display as the "Left Image" using the search box, and a species to display as the "Right Image."

Click and drag the maroon handle over the maps to compare. You can also click the species label below the images to only display that species map image.

Potential Changes in Abundance and Range (Future)

Percent 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. There are a total of 9767 cells used in the model.

Ave. IV is the average importance value across all 20x20 km cells that have been modeled to be suitable for the species.

Sum 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 IV is the ratio of change between the modeled current Sum IV and any of the GCM scenarios Sum IV. This value is not available for the current FIA and current modelled.
