List of national forests of the United States

The United States has 154 protected areas known as national forests, covering 188,336,179 acres (762,169 km2; 294,275 sq mi).

[2] The first national forest was established as the Yellowstone Park Timber and Land Reserve on March 30, 1891, then in the Department of the Interior.

The management goals provided by the Organic Act were expanded upon by the Multiple-Use Sustained-Yield Act of 1960 to include "outdoor recreation, range, timber, watershed, and wildlife and fish purposes" as well as for the establishment of wilderness areas.

[A][1][4][5] There is at least one national forest in all but ten states: Connecticut, Delaware, Hawaii, Iowa, Kansas, Maryland, Massachusetts, New Jersey, North Dakota, and Rhode Island (although Kansas and North Dakota have national grasslands).

In addition, Puerto Rico contains El Yunque National Forest, the only tropical U.S. rainforest.
