When you camp or hike in a national forest, it’s easy to assume that forest is as it’s always been. Trees, trails, flora, fauna. But there are more than 193 million acres of national forest across the United States, and maintaining the health of the diverse ecosystems encompassed with the national forest system takes a lot of work. The National Forest Foundation is the non-profit “friends of” arm of the National Forest Service, and its efforts helped reforest more than 14,000 acres in 2023 alone.
