Is It Illegal to Cut Down Koa Wood in Hawaii?

Quick Summary: No, it is not automatically illegal to cut down a koa tree in Hawaiʻi. Whether harvesting koa is legal depends on where the tree is located, who owns the land, the classification of that land, and whether required authorization, permits, or management plans are in place. Unauthorized cutting or removal of koa and other timber from State forest reserves is prohibited.  However, removing koa trees from private land may not have the same constraints.

Koa is one of the most treasured natural resources of Hawaiʻi.  Koa is also endemic to Hawaiʻi, meaning it occurs naturally nowhere else in the world. For generations, Native Hawaiians used koa to create waʻa (canoes), surfboards, tools, weapons, furniture, and other important objects.

Today, koa remains culturally significant and has also become one of the world’s most desirable hardwoods. That creates an important question for anyone buying koa furniture, bowls, jewelry, watches, artwork, musical instruments, or other handcrafted products:

Is it illegal to cut down a koa tree in Hawaiʻi?

• The accurate answer is:  No. Not necessarily.

• There is no blanket rule saying that every living koa tree in Hawaiʻi is legally protected from being cut under every circumstance. The legality of harvesting koa depends upon where the tree is located, who owns the property, how that land is classified, and which laws, permits, authorizations, or management requirements apply.

Here are the facts.

1. Koa Is Uniquely Hawaiian

Hawaiian koa is a particular species called acacia koa. Hawaiian koa grows no place else but Hawaii.  Other species of acacia grow elsewhere around the world. But all acacia and NOT Hawaiian koa. Customers should not be fooled into thinking all acacia is koa. It is not.

Koa is endemic to the Hawaiian Islands and therefore has a special place in Hawaiʻi’s natural and cultural heritage.  Historically, koa was prized by Native Hawaiians for waʻa, surfboards, tools, weapons, and other important objects.

Today, its remarkable grain, color, figure, and rarity make it highly desirable for furniture, musical instruments, artwork, bowls, jewelry, watches, and other fine products.

Because koa is both culturally important and commercially valuable, responsible management of Hawaiʻi’s koa forests is extremely important.

2. Cutting a Living Koa Tree Is Not Automatically Illegal.  This is one of the most important facts to understand.

It is not accurate to say that cutting down any living koa tree anywhere in Hawaiʻi is always illegal.  The legality depends heavily on where the tree is growing and who owns or manages the land.

A koa tree growing on private property is in a different legal situation from a koa tree growing within a State forest reserve.  Private landowners may be able to harvest trees on their property, but applicable conservation, zoning, environmental, land-use, easement, permitting, or other requirements may still apply.

Therefore, consumers should not assume that koa is illegal merely because it came from a harvested living tree. The more useful question is:  Was this koa legally and responsibly obtained?

3. You Cannot Simply Enter a State Forest and Cut Down Koa

The rules about cutting Koa are much clearer on State of Hawaii land.  Hawaiʻi law prohibits the unauthorized cutting, killing, damaging, or removal of timber, young tree growth, or products of tree growth from State forest reserves.

In practical terms:

• You cannot simply enter a State forest reserve and select a koa tree to cut down.

• You cannot assume that a fallen koa tree on State land is yours to take.

• You cannot remove koa merely because you discovered it.

• Authorization from the appropriate government agency may be required.

4. Hawaiʻi Actually Allows Some Managed Timber Harvesting

There is a critical distinction between legal forestry and unauthorized harvesting or timber removal.  It is wrong to say Hawaiʻi prohibits all timber harvesting on public land.  It does not.

State of Hawaii Timber Management Areas:  The State has designated Timber Management Areas intended for sustainable production of forest products.  Harvesting activities on State-owned lands must be conducted under applicable management plans and environmental and conservation requirements.  This illustrates two important points:

1. Responsible harvesting can occur as part of an authorized forest-management program.

2. Harvesting a tree and illegally cutting a tree are not the same thing.  In fact, Hawaiʻi has established the Kapāpala Koa Canoe Management Area on Hawaiʻi Island specifically to create a sustainable, long-term supply of koa suitable for traditional Hawaiian canoe construction.

The State’s management plan balances koa harvesting with protection of native forests, watersheds, wildlife habitat, biodiversity, and cultural resources.

It is blatantly wrong to make the sweeping statement that “it is illegal to cut down a koa tree in Hawaiʻi.”  The real issue is where, why, how, and under whose authorization the tree is harvested.

5. Previously Fallen Koa Provides an Important Source of Wood

Koa trees naturally fall for many reasons, including:

• Age

• Wind and storms

• Disease

• Erosion

• Natural forest processes

Those fallen trees can contain extraordinary wood.  In many  cases, mature fallen koa produces remarkable grain, curl, figure, and coloration that make it particularly desirable for fine woodworking.  Using koa from previously fallen trees allows craftspeople to transform an existing natural resource into furniture, artwork, bowls, jewelry, watches, and heirloom pieces without cutting down a healthy living tree specifically to manufacture that product.

However, there is another important legal distinction:

• A fallen koa tree is not automatically free for anyone to take.

• The tree and its wood remain associated with the property on which they are located. On government-managed land, removing fallen wood may require authorization.

• “Fallen” should therefore never be confused with “free for the taking.”

6. The Provenance of Koa Matters

This brings us to one of the most important considerations for consumers:  Where did the koa come from?  This is called provenance.

A reputable seller of koa products should understand its supply chain and have confidence that the wood it purchases was obtained legally and responsibly.  Before purchasing an important koa piece, consider asking:

• Is this genuine Hawaiian koa?

• Is the species actually Acacia koa?

• Where in Hawaiʻi did the wood originate?

• Does the seller know who supplied the wood?

• Was the wood obtained legally?

• Was it harvested from a living tree or salvaged from a previously fallen tree?

• Can the seller explain its standards for purchasing koa?

The more significant the purchase, the more important these questions become.  If you are purchasing an heirloom koa dining table, bed, rocking chair, sculpture, or other substantial piece, you should know what you are buying.

7. Hawaiian Law Protects Consumers From Fake “Koa”

There is another important part of Hawaiʻi law that koa buyers should understand.  The word “koa” itself is regulated when wood products are offered for sale in Hawaiʻi.

Hawaiʻi law states that a person may not offer, display, expose for sale, or solicit the sale of timber, lumber, wood, or a wood product described or labeled using the term “koa” unless the item is Acacia koa.  This is extremely important for consumers.

Other species of acacia may sometimes have an appearance resembling koa.  But acacia is not automatically Hawaiian koa.  If you want genuine Hawaiian koa, you should be buying Acacia koa.

That is not merely a marketing distinction. Hawaiʻi law specifically addresses how the term “koa” may be used when wood and wood products are offered for sale.

8. “Acacia” and “Koa” Should Not Be Used Interchangeably

Consumers shopping online may encounter products described with terms such as “acacia,” “Hawaiian-style wood,” or descriptions that imply a connection with koa.  Buyers should look carefully at exactly what they are purchasing.

Koa belongs to the broader acacia group, but that does not mean every acacia tree is koa.  Think about it this way:  All genuine Hawaiian koa is Acacia koa, but not all wood called acacia is Hawaiian koa.

That distinction becomes particularly important when a product commands the premium price associated with genuine Hawaiian koa.  If you are paying for koa, you should receive genuine koa.

9. Responsible Koa Purchasing Helps Protect Hawaiʻi’s Forests

The question of koa harvesting goes beyond legality.  It is also about stewardship.

A living koa tree is part of a larger Hawaiian ecosystem. Koa forests can provide habitat for native species, contribute to watershed health, encourage native biodiversity, and form part of Hawaiʻi’s extraordinary natural landscape.

Responsible forest management therefore considers much more than the commercial value of a board of lumber. It considers the future of the forest. That is why consumers should support businesses that understand where their koa comes from and take its provenance seriously.

10. Martin & MacArthur’s Approach to Koa

At Martin & MacArthur, we believe that the beauty of koa comes with a responsibility to respect the resource from which it came.  Martin & MacArthur does not cut down living koa trees to manufacture our products.

Our approach is to use koa obtained from previously fallen trees and to work with established sources whose provenance we know and trust.

We believe beautiful koa products should come from a responsible and traceable source.  A magnificent koa tree may have lived in a Hawaiian forest for generations. When a tree eventually falls naturally, its wood can be given another life.

In the hands of Hawaiʻi’s craftspeople, that wood can become a dining table, rocking chair, bowl, watch, sculpture, work of art, or family heirloom capable of lasting for generations more.

Conclusion: Is It Illegal to Cut Down Koa in Hawaiʻi?

No—not in every circumstance.  There is no universal law stating that every living koa tree in Hawaiʻi can never legally be cut down.  Instead, the legality of harvesting koa depends upon factors including:

• Who owns the land

• Where the tree is located

• How the land is classified

• Whether government authorization is required

• Whether applicable permits are required

• Whether a management plan governs the harvesting

• Whether applicable environmental and conservation requirements have been satisfied

• Unauthorized cutting or removal of timber from State forest reserves is prohibited.  At the same time, Hawaiʻi permits certain properly authorized and managed forestry activities—including carefully controlled harvesting on State lands under approved management programs.

For consumers, therefore, the most important question isn’t simply:  “Was a tree cut?”  Instead, akamai (wise) consumers should ask:  “Where did this koa come from, and was it obtained legally and responsibly?”

And there is one more question every buyer should ask: “Is this actually Hawaiian koa?”  Ask of a retailer has certificates of Authenticity for the wood it sells.  Hawaiʻi law specifically protects the meaning of the word “koa” when wood products are offered for sale. 

When you purchase a beautiful koa piece, you are purchasing more than wood. You are acquiring something created from one of Hawaiʻi’s most distinctive natural resources. Its provenance should matter as much as its beauty.

Frequently Asked Questions About Koa

Q: Is it illegal to cut down a koa tree in Hawaiʻi?
A: Not automatically. The legality depends upon the location of the tree, ownership and classification of the land, and the permits, authorizations, management plans, and other regulations that may apply.

Q: Is it illegal to cut koa in a State forest reserve?
A: Unauthorized cutting, damaging, or removal of timber and tree products from State forest reserves is prohibited. Properly authorized harvesting can occur under applicable State management programs and requirements.

Q: Can someone cut a koa tree growing on private property?
A: Potentially. Private ownership does not necessarily mean that every tree can be harvested without restriction. Conservation, land-use, environmental, zoning, easement, permitting, or other requirements may apply to a particular property or harvesting operation.

Q: Can I take koa that I find lying on the ground?
A: Do not assume so. A naturally fallen tree is not automatically free for public collection. Ownership of the land and applicable rules still matter, and removing wood from government-managed land may require authorization.

Q: Does Hawaiʻi allow any koa trees on public land to be harvested?
A: Yes, under controlled circumstances. Hawaiʻi law provides for harvesting on State-owned lands under approved management plans and applicable conservation and environmental requirements. The Kapāpala Koa Canoe Management Area is an important example of koa being sustainably managed for traditional canoe construction.

Q: Is acacia the same as Hawaiian koa?
A: Genuine Hawaiian koa is a specific species of acacia called acacia koa. However, other acacia species are not Hawaiian koa simply because they have a similar appearance or name.

Q: Can a company legally call another species of acacia “koa”?
A: Hawaiʻi law prohibits offering wood or wood products described or labeled using the term “koa” unless the item is Acacia koa. 

Q: What is the most important thing to ask when buying koa?
A: Ask two questions: “Is this genuine Hawaiian Acacia koa?” and “Where did this koa come from?” A reputable seller should understand the provenance of its wood and be confident that it was legally and responsibly obtained.
