FOREST INVENTORY AND ANALYSIS (FIA)

FIA US county-level map:

All 3,142 counties, boroughs and parishes in the United States are delineated on this map as an illustration of the research capacity within the U.S. Forest Service’s Forest Inventory and Analysis Program [FIA]. Move your cursor over any of these local government units and you will be amazed at the fine-scale data sets that are available for your reference use.

This map is but the beginning of the FIA story we will be telling in the coming weeks. We have been using FIA data sets in Evergreen Magazine for 30 years. They are unblemished, unbiased and backed by decades of field research, which is why we consider them to be forestry’s gold standard. In succeeding reports, we will be introducing more interactive maps, data sets and links that lead to peer-reviewed research that rarely makes its way into the public discourse.
