The American Tree Farm System® (ATFS) is the largest and oldest sustainable family woodland system in America. Through our forest certification program, we provide Tree Farmers with the confidence and validation that they are doing right by their land. Family forest owners that certify their woodlands through ATFS join a national network of woodland owners who are globally recognized for their good stewardship. ATFS certification is internationally recognized and meets strict third-party verification and audit standards. As a Tree Farmer, the Standards can assist you in managing your woodlands to achieve your own goals while maintaining a healthy and productive forest. The Standards delineate best management practices and address four key areas: Water, Wildlife, Wood and Recreation. Through the Standards, you can document your progress on the ground. The Standards recognize new conservation forestry practices and evolving consumer demand for sustainably harvested forest products. Once ATFS verifies that the Standards are met and the Tree Farm is certified, landowners can proudly display the ATFS green and white sign, the national symbol for good forestry.
