Green-up duty

Several local organizations have registered to participate in National Public Lands Day. The event—which is officially Saturday, September 29—is the largest annual public-land cleanup activity in the nation, with federal agencies, nonprofits and other local government agencies participating. Some cleanup events within 50 miles of Sacramento—at sites such as the Cosumnes River Preserve, Miner’s Ravine Bike Trail and Beale Air Force Base—happen as early as this weekend, while others continue throughout September and October. Cleanup and improvement tasks include habitat restoration, water-quality monitoring, painting, landscaping and picking up litter. Visit www.publiclandsday.org for more information.
