The document summarizes land preservation efforts in Concord, Massachusetts. Approximately 35% of the land, or 5,900+ acres of the town's 16,541 acres, has been permanently protected through a combination of federal, state, town-owned, private land trusts and privately owned land subject to conservation restrictions. This includes 637 acres of federal land, 387 acres of state land, and 1,360 acres of town-owned land. Private efforts and partnerships between public and private groups have helped increase land protection since the 1950s.
