Mālama Nā Koʻolau Day at Mānoa Cliff Restoration Site

Join in for a fantastic day caring for our native forest at

The Mānoa Cliff Restoration Site!

Volunteers with our Mālama Nā Ko’olau Program will have opportunities to clear invasive species and protect native forests to grow watershed resources and empower community action. This forest restoration work helps protect native plants and animals, reduces risks of environmental disasters like floods and fires. Our goal is to empowers local communities through knowledge and experience to help them build effective stewardship programs.

Who: Anyone who is interested in learning about our native forests and caring for these incredible places is invited to be part of the restoration project. Participants of all ages and ability levels are welcome, but only registered KMWP volunteers can join these events. You must turn in your completed volunteer application forms by June 16th to be eligible.

The 2026 volunteer forms and instructions can be found here.

We have 25 spots open for each session and they are filled on a first come first serve basis, any additional volunteers who sign up will be placed on a waiting list.

What: This is a Service-learning opportunity, the volunteers will be clearing invasive species and protecting native forests to grow our watershed resources and empower community action.

When: 9am to 12pm; Meet at the parking lot at 8:30am for check-ins. After a quick walk to the worksite, the volunteer activity will go until 12:00pm with an optional walk through the site at the end to see some of the incredible native species living there.

Where: Manoa Cliff Restoration Project. Park at the trailhead for Puʻu ʻŌhiʻa trail and meet the KMWP staff. We will lead a short hike to the site. Keep in mind that the trailhead parking lot is quite small, so carpool whenever possible.

Why: This site is on public lands and is frequented by hikers from all over the world. That amount of traffic through the area presents a lot of challenges but also a great opportunity to teach, learn, and care for a high-impact site. This location has been stewarded by the Mānoa Cliff Restoration Project for over 20 years and the oasis of native diversity they created in that time serves as a really good example of what a dedicated effort at conservation and reforestation can accomplish.
