How can I download the database for Importance Value and Species for all/some of the eastern states?
You can download the IV-Species data for current-FIA and all the GCM model scenarios. On the launch pad page click on “Outputs for ALL 80 Species Combined” -> “Ranked Species List” -> “Current” (or any of the 5 scenarios). At the bottom of the eastern US image map, there is an option to download the entire database (about 3-4 MB). This should give you a sorted SpeciesName-IV list for each county for all the eastern states OR alternatively you can click on any state you want and get the database for all counties in that state.
