Forest Inventory and Analysis

Forest Inventory and Analysis (FIA) collects, analyzes, reports, and distributes data about the Nation’s forests: how much forest exists, who owns it, what condition it's in, where it’s located, and how it's changed.

The Northern Research Station FIA unit is responsible for creating and maintaining a comprehensive forest inventory for 24 States: Connecticut, Delaware, Illinois, Indiana, Iowa, Kansas, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota, Vermont, West Virginia, and Wisconsin. The forests in these States cover about 174 million acres or about 30 percent of the land here. 

Data from FIA are used everyday to assess sustainability, to make important business decisions, to evaluate wildlife habitat, and for many other things. National, State, and local policy makers, universities, businesses, tribal governments, national forests and other natural resource agencies, interest groups, and many others depend on FIA for timely, scientifically credible information about our forests.
