Community Volunteer Opportunities on Oahu

- by

“The best way to find yourself is to lose yourself in the service of others.” – Gandhi 

Volunteering can be a wonderful way to connect with and give back to the ‘aina and community. The organizations listed below have ongoing volunteer opportunities.

Honouliuli Forest Reserve 

Do you enjoy being in an untrampled area with few other hikers and doing something for the native, natural environment? Every Thursday a group of volunteers head into the Honouliuli Forest Reserve to work in the forest caring for and planting natives as well as removing invasive plants and trees. Most of the volunteers are seniors and laughingly call themselves Senior Day Care. For more information contact: Ed at

Akupu Enclosure

Akupu Enclosure is a native dryland forest restoration project in Gill Ewa Lands above Makakilo.  Once a month we plant, weed and/or water trees.  We started in March 2019 and have planted hundreds of trees, bushes and ground cover. We meet at Makakilo Community Park. Contact Randy Ching at if interested.

Lyon Arboretum

Hosts monthly Group Volunteer Work Days every 3rd Saturday at 8:00 AM. Email Tylor Schwarze to reserve a spot. The goal is to get as many hands as possible out in the field working to re-establish native Koa trees. The end result will be a forest of Koa trees to be enjoyed for many years to come.
