The Adirondack Park Agency celebrated Arbor Day 2011 with a tree planting in honor of Clarence Petty. Petty was one of the first employees at the Adirondack Park Agency following a long career with the NYS Conservation Department. He served on the Pomeroy Commission (Inter-Legislative Committee on Natural Resources) and the Temporary Study Commission on the Adirondacks.
Mr. Petty had a profound impact on the Adirondack Park and is considered one of the most influential environmentalists of the 20th century.
