List of the Largest National Forests in the U.S.

National Forests of the U.S.: National Forests represent an essential component of America’s natural resources. They are great sources for pure atmospheric air, sparkling filtered water, and habitats for many wildlife species, as well as areas for people to participate in nature’s bounties. The National Forest System includes a diverse range of ecosystems across millions of acres of land, with many of these ecosystems continuing to exist for tens of thousands of years, as well as providing for recreational purposes, educational opportunities, and protecting our natural resources. The National Forests include everything from snow-capped mountains to arid deserts to lush coastal rainforests and reflect the geographic and biological diversity of the United States.

The United States National Forest System is managed to balance environmental protection with public use. These forests support many plant and animal species, including many that are rare or endangered. They also preserve historical, cultural, and archaeological sites that tell the story of earlier civilisations and natural evolution. 

Among the many national forests across America, some stand out for their sheer size. These forests cover vast areas, often larger than entire states or countries, and play a critical role in environmental stability.
