American Revolution and U.S. Constitution Bicentennial Living Witness Trees Historical Markers

The International Society of Arboriculture and the National Arborist Association (now called the Tree Care Industry Association) decided to combine national history with natural history by creating a bicentennial tree recognition program. Communities around the country nominated significant trees that were over 200 years of age, with 61 trees certified as "living witnesses" to the time of the Constitution's signing on September 17, 1787. This series also includes markers by the same organizations honoring American Revolution witness trees.
