Celebrate Something We All Share: Our Public Lands!

On September 27, 2025, join thousands of people at sites throughout the nation and take part in National Public Lands Day (NPLD). NPLD is the nation’s largest, single-day volunteer effort for public lands.

The Army Natural Resources Program, Oʻahu (ANRPO) is hosting two days at the summit of Ka’ala, controlling invasive species that threaten to overtake the native forest species (September 27) and rebuilding the boardwalk that allows visitors to safely traverse/enjoy Kaʻala (November 15).

PROJECT: We will control invasive species (Koster’s curse, Florida blackberry, montbretia, common rush) using small hand tools (e.g., hand saws, pruners, protective gloves). We will apply herbicide (Garlon4 for Koster’ curse) to the cut stumps and manually remove the other invasive species.

After the service portion of each day, we will take time to enjoy an interpretive native plant and animals’ hike along the Ka’ala boardwalk and nearby area. Staff will provide natural resource and cultural history information on the area as we hike along the trail.

HIKING TIME: 1 hour (round trip)

DIFFICULTY: Easy; level trail along boardwalk.

WHAT TO BRING: A complete list of what to bring for each project will be emailed to participants once confirmed on the sign-up list.

All sign-ups can be found on www.oanrp.com

All weeding tools and gloves will be provided.
