The National Forest System is a network of protected public lands in the United States, managed by the U.S. Forest Service. It was established to conserve natural resources, provide recreational opportunities, and support wildlife habitats. The system includes 154 national forests and 20 national grasslands, covering over 193 million acres. These lands are open to the public for various activities, such as hiking, camping, and fishing. The National Forest System also plays a crucial role in sustainable forestry practices, helping to maintain healthy ecosystems while providing timber and other resources for communities.
