The Tolowa Dunes Stewards continue a series of summer nature programs this month focusing on the impact climate change has on the dune environment as well as the elk population that calls the area home.

The organization is also seeking volunteers in its continuing efforts to pull and remove invasive European beach grass, according to an organization press release. The next restoration effort is 1 p.m.-4 p.m. Sunday.

On Aug. 12, U.S. Forest Service ecologist Andrea Pickart will give a presentation on coastal dune formation and will lead a field trip to a recently restored area that demonstrates the importance of projecting dune habitats, according to the press release.

Another restoration effort will be held at Big Dune on Aug. 19.

The Tolowa Dunes Stewards will round out August with a slide presentation from Humboldt State University wildlife professor Micaela Gunther on the Roosevelt elk population on Aug. 26.

Activities are also sponsored by the Redwood Parks Conservancy in collaboration with the California Department of Fish and Wildlife and California State Parks. They are held at 1 p.m. Sundays at the Lake Earl Wildlife Information Center, 2591 Old Mill Road, Crescent City.
