The United States of America has a remarkable forest resource—more than 765 million acres of planted and natural forest land and an additional 58 million acres of woodlands. These lands provide clean water, clean air, wildlife and fish habitat, recreational opportunities, and for nearly four centuries have been the foundation for economic development. This atlas introduces the reader to a trove of information also available online at the forest atlas website, https://forest-atlas.fs.fed.us.
Evolving from the first inventory of U.S. forests in the 1870s, the Forest Inventory and Analysis (FIA) program rigorously monitors the health and productivity of forests and the many benefits they provide. This atlas combines inventory and monitoring information from the 1870s to the present day with datasets prepared by other partners on wilderness, wildland fire, wildlife, and other issues to tell stories about the value of the Nation's forests and the challenges they face.
Advances in technologies and analytical methods and the availability of other spatial data, such as satellite imagery and digital elevation models, now make it possible to present information about U.S. forests in novel ways. Much of the content is this atlas is derived from over 355,000 field plots, more than 19 million tree observations (some trees have been measured more than once to estimate growth), and two decades of satellite imagery that are transformed into rich and comprehensive information spanning the Nation's entire forested landscape. Sources for all of the content published here are provided in the back matter.
