Nurture native ecosystems

The most endangered place you will love.

Most of Hawaiʻi's dry and lowland forests are already gone. What's left catches the clouds that fill the aquifers, holds the soil off the reefs, and shelters birds found nowhere else on Earth.

  • Water

    Native forest recharges the islands’ drinking water

  • Reefs

    Rooted hillsides keep runoff off the coral

  • Habitat

    Honeycreepers survive only in native canopy

Travel that gives back

Before your trip. After your trip. Make it better.

Ten million visitors arrive each year, and every trip leaves a carbon footprint. Sponsor trees before you fly and arrive knowing trees are already growing or start it on the plane home, while the islands are still in your head.

Mālama ʻāina — care for the land, and the land cares for you.

What it takes

It starts with a seed.

Every sponsorship funds the full journey: seed collection, nursery care, careful planting, and years of tending, so each tree has a real chance at becoming part of the canopy.

Seed

Genetically diverse seed collected from surviving native stands.

02

Nursery

Grown under shade cloth until strong enough for a first dry season.

03

Planting

Sites cleared of invasive grass and fenced against grazing animals.

04

Care

Watering, weeding, and monitoring for years, when most loss happens.

What you are planting

Native species only.

Some species options include the list below. Our team selects the right mix for each site, because a healthy blend of native species is better for the forest in the long run.

Where your trees are planted

ʻIole, North Kohala, Hawaiʻi Island

Your trees go into the ground at ʻIole, a nonprofit research center on the northern tip of Hawaiʻi Island. The same hillside teaches ʻāina-based science to Kohala students.

Frequently asked questions

Why does one tree cost $25? Isn’t it usually $1?

Dollar-a-tree programs skip the hard parts: site prep, species selection, fencing, and years of care. $25 covers a tree’s full lifecycle, so it is still standing decades from now.

Do I have to be traveling to Hawaiʻi to participate?

No. Many subscribers have never visited. But if you are going, or just got back, this is the most direct way to balance the trip.

Will I get photos of my trees?

Yes. After planting. Germination comes first, then the next planting season. We wait until trees are established before sending images.

Which species will my tree be?

Koa, ʻōhiʻa lehua, kamani, milo, kou, kukui, among others. The mix follows what the hillside needs: a biodiverse forest survives where a monoculture does not.

Can I give once, or change my plan later?

Both. Give once or start a monthly plan, and switch or cancel anytime from the billing portal link in your receipt email. If you choose to subscribe, there is no cancellation fee. Trees already funded stay funded.
