The U.S. National Forest System is a network of protected public lands managed by the U.S. Forest Service, part of the U.S. Department of Agriculture. It includes 154 national forests and 20 national grasslands, covering over 193 million acres across the country. These areas are designated for multiple uses, including recreation, wildlife habitat, and timber production. The primary goal of the National Forest System is to sustain the health, diversity, and productivity of the forests and grasslands. This system provides opportunities for outdoor activities such as hiking, camping, and fishing, while also conserving natural resources and protecting ecosystems.
