Established in 1994 and held annually on the fourth Saturday in September, National Public Lands Day is traditionally the nation’s largest single-day volunteer effort. It celebrates the connection between people and green space in their community, inspires environmental stewardship, and encourages use of open space for education, recreation, and health benefits. This year, National Public Lands Day falls on September 24, 2022.
