National Trails Day is held the first Saturday each June. This nationwide event draws people together to celebrate trails as they complete trail work projects. The improvements to our public lands accomplished through National Trails Day projects contribute to the long-term health and maintenance of these lands and trails.

On June 6, 2009, more than 70 volunteers accomplished a number of National Trails Day projects at Campbell Tract. Volunteers installed and painted a post-and-rail fence at Smokejumper Trailhead, spread gravel and soil along the edge of the parking lot and roadway, and revegetated the area behind the new fence. Nearby, other volunteers worked to revegetate the old section of Moose Track Trail. Volunteers also spread gravel and brushed sections of other trails, watered revegetatation sites along the Science Center Road, and planted native perennials in the gardens in front of the Science Center.
