Volunteer Opportunities

Aloha Friday Watering

Every Friday, we gather at the trailhead to strategically place water along the trail and give our thirsty plants a much-needed drink. These are smaller volunteer sessions, and extra helping hands are always welcome!

Monthly Community Workdays

On the third Saturday of each month, we invite the whole community to the trail to help clear kipukas, remove invasive species, repair trail cuts, and plant new trees. All ages are welcome —come join us, pitch in…

Nursery Management

We’ll soon be inviting volunteers to support our new Native Hawaiian plant nursery in Kamilo Nui. Volunteer activities will include mixing soil media, removing weeds, up-potting plants, and planting seeds.
