Kentucky Heartwood is Celebrating 30 Years of Forest Protection! We are a non-profit forest advocacy organization that has worked since 1992 to protect and restore the integrity, stability, and beauty of Kentucky’s native forests. Our focus is the Daniel Boone National Forest in southeastern Kentucky. The 700,000 acre public forest boasts the state’s highest concentration of rare species, one of the highest concentrations of archaeological sites in the southeast, over 3,000 miles of clifflines, and attractions like the Red River Gorge.
