The National Park Service Land Resources Division maintains official acreage data for all units of the National Park System. Beginning in 2022, acreage reports will be published at the end of every quarter. Prior to 2022, reports were produced only at the end of the calendar year and fiscal year. Reports are provided in Excel format and include separate listings organized by park unit, by park type, and by state.
