National Public Lands Day (NPLD) is the largest volunteer event for America's public lands. NPLD is held on a Saturday in late September when thousands of Americans volunteer to improve and enhance our nation's public lands. National Public Lands Day 2012 will officially take place on September 29, 2012. In BLM California, NPLD events will also take place on other days during the fall.
