Secretary of the Interior Ken Salazar joined volunteer and youth groups at Shenandoah National Park as part of a national kickoff for President Obama’s new “United We Serve” campaign. The Secretary helped the groups remove nonnative plants that have invaded the natural ecosystem adjacent to Big Meadows Swamp.

Groups participating with him at the cleanup near Skyline Drive included Volunteers-in-the-Parks, the Shenandoah National Park Association, Student Conservation Association, Youth Conservation Corps, Potomac Appalachian Trail Club and Shenandoah National Park Trust.
