Olympic National Park and the Friends of Olympic National Park host two volunteer events to remove invasive plants and plant native species in the national park’s headquarters district on Saturday, Sept. 24, on National Public Lands Day, the nation’s largest single-day volunteer effort on public lands.

Members of the public are invited to join in these projects to take part in this nationwide celebration of public lands and volunteerism.

One event sees volunteers native plant species in the areas surrounding the historic Macy House — home to Preston Macy, Olympic National Park’s first superintendent — from 9 a.m.-noon. This event will begin at the flagpole in front of the Olympic National Park Headquarters Building, located at 600 E Park Ave., Port Angeles. Sign up to volunteer at tinyurl.com/9drmc82x.

A second volunteer event is set to remove invasive plants along the trails and areas surrounding the national park’s visitor center. Participants will learn about invasive plants and their disruptive impact on park ecosystems while helping to remove herb Robert and wall lettuce.

National park rangers will lead volunteer groups starting at 10 a.m. and 1 p.m. Both groups will meet at the Olympic National Park Visitor Center, 3002 Mount Angeles Road, Port Angeles.
