Mālama Nā Koʻolau Volunteer Day at Wiliwilinui Restoration Site
Ko’olau Mountains Watershed Partnership
Join in for a fantastic day caring for our native forest at
The Wiliwilinui Trailside 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 application forms or RSVP by the event deadline to be eligible.
Visit the KMWP events Calendar for more information and to RSVP.
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 service-learning day will be focused on invasive species removal and protecting native plants in the area. There may be some seed bomb throwing as well as some seed collection, brush clearing, and trail work. We will also be offering an interpretive hike further up the trail after the workday is done.
When: 9am to 12pm
Meet at the gate near the trailhead at 8:30am for check-ins, after a quick walk to the worksite the volunteer activity will go until 12:00pm
There will be an optional interpretive hike to follow the event, approximately 12:30-2:00pm
Where: Wiliwilinui Trailside Forest Restoration site
We will meet at the Wiliwilinui trail parking lot or a designated meeting spot. After check-ins, we will hike about .7 miles from the gate up to the worksite. Keep in mind that the trail access is through a gated community and you will need to show ID and sign in at the gate. Parking space is limited so please consider going with a friend or carpooling if possible.
Why: This site is a great example of how much of a difference we can make for native species by combating invasive trees like strawberry guava and making room for the native ones to have a fighting chance to grow and thrive. It is also along a fairly popular trail and volunteers will be able to continue their adventures after we finish up with the projects. The site is in its restoration infancy, but it really shows us what regular efforts from a small but dedicated group can do for our native forest habitats and gives us hope for the future and the thriving native forests that we can build together.
Forest restoration work helps to not only protect our native plants and animals, but it also serves the communities of the Ko’olau by reducing the risks of environmental disasters like floods and fires. These events are built to empower local communities through knowledge and experience and build up their capacity as stewards of the land. It is about getting positive work done, enhancing our watershed resources, and laying the foundation for future generations.

Ko’olau Mountains Watershed Partnership
About the organizer
KMWP works across over 103,000 acres of the Ko’olau Mountains. Our partnership was formed with the goal to protect our watershed resources and increase the recharge of our aquifers with high quality water through active conservation of our forested lands.
We work across landowner boundaries to eliminate threats to the watershed such as habitat-modifying invasive weeds and ungulates like goats and wild boars. Our focus is on combining protection with restoration using a adaptive management strategies and established conservation practices. These methods include the installation of ungulate-proof fencing, various weed removal techniques, restoration planting, and long-term monitoring.
We also reach out to local communities, individuals, and organizations to empower them with the knowledge and skills needed to become effective stewards of their land. We host educational presentations, workshops, and service-learning opportunities, to give everyone the chance to learn about and protect the native ecosystems and watershed resources of the Ko’olau Mountains.
