**President Obama has expanded the Papahānaumokuākea Marine National Monument to 582,578 square miles—more than four times its previous size and larger than any other protected land or ocean area on Earth.**

The proclamation signed Friday extends federal protection around the remote Northwestern Hawaiian Islands from 50 nautical miles in most places to the 200-mile limit of the United States’ exclusive economic zone. The action adds 442,781 square miles of Pacific Ocean to a monument first created by President George W. Bush in 2006.

The [presidential proclamation](https://obamawhitehouse.archives.gov/the-press-office/2016/08/26/presidential-proclamation-papahanaumokuakea-marine-national-monument?ref=theamericanquorum.com) prohibits commercial fishing and mineral extraction in the expansion area while allowing permitted scientific research, recreational fishing and Native Hawaiian cultural practices. Existing military navigation, national-security activities and uninterrupted vessel passage may continue.

## A protected area larger than Alaska

The monument now covers about 1.5 million square kilometers, an area roughly twice the size of Texas and larger than the total land area of Alaska. A [National Oceanic and Atmospheric Administration announcement](https://sanctuaries.noaa.gov/news/aug16/president-announced-expansion-of-papahanaumokuakea-marine-national-monument.html?ref=theamericanquorum.com) said the expansion makes Papahānaumokuākea the largest conservation area on the planet.

The protected waters surround a chain of small islands, atolls, submerged banks and seamounts stretching northwest from Hawaii’s main islands. Though remote from most people, the region supports more than 7,000 marine species, roughly a quarter found nowhere else. It is home to endangered Hawaiian monk seals, green sea turtles, whales, sharks, tuna and millions of seabirds.

The archipelago’s ecological significance is matched by its cultural importance. Native Hawaiian traditions regard it as a place of origin and return, connecting human life with the natural world. The site was inscribed on the UNESCO World Heritage List in 2010 for both natural and cultural values; [UNESCO’s description](https://whc.unesco.org/en/list/1326/?ref=theamericanquorum.com) emphasizes its importance to endemic birds, monk seals and other vulnerable species.

## Commercial extraction ends across the expansion

The White House said all commercial resource extraction—including fishing and any future seabed mining—will be prohibited. The [administration’s fact sheet](https://obamawhitehouse.archives.gov/the-press-office/2016/08/26/fact-sheet-president-obama-create-worlds-largest-marine-protected-area?ref=theamericanquorum.com) allows noncommercial fishing by permit and preserves removal of resources for Native Hawaiian cultural practices.

The ban has drawn opposition from segments of Hawaii’s longline fishing industry, which argues that U.S. boats operate under rigorous quotas and monitoring while foreign fleets fish nearby international waters. Industry representatives say excluding American vessels could shift catch rather than reduce it, increasing imports without creating equivalent protections beyond U.S. jurisdiction.

Supporters respond that large no-take areas offer benefits that conventional species-by-species management cannot. They protect food webs, spawning grounds, deep-water coral and migratory corridors together, establishing a refuge against fishing pressure, mineral extraction and other industrial disturbance.

[Reuters reported](https://www.reuters.com/article/us-usa-obama-oceans-idUSKCN111083/?ref=theamericanquorum.com) that the proclamation will ban commercial fishing across more than 582,500 square miles and forms part of Obama’s broader conservation and climate agenda. The president is expected to visit Midway Atoll next week to highlight warming oceans and coral stress.

## Climate protection through ocean scale

Papahānaumokuākea contains coral reefs, deep-sea habitats and black corals that can live for thousands of years. Large marine reserves cannot stop ocean warming or acidification at their boundaries, but they can reduce other pressures, giving ecosystems more capacity to withstand environmental change.

The expansion also prevents future seabed mining in an area believed to contain mineral deposits. Scientists are still documenting species and ecological connections in the monument’s deep waters, making precaution itself a central argument: the government is protecting habitats before industrial uses can be established.

Interior Secretary Sally Jewell and Commerce Secretary Penny Pritzker said the decision followed engagement with Native Hawaiian leaders, fishermen, scientists and residents. Their [joint statement](https://www.doi.gov/pressreleases/secretaries-pritzker-jewell-applaud-presidents-expansion-papahanaumokuakea-marine?ref=theamericanquorum.com) also recognized a stronger management role for the Office of Hawaiian Affairs, reflecting demands that cultural authority accompany federal conservation.

## Executive power and local consent

Obama acted under the Antiquities Act, a 1906 law allowing presidents to protect federal lands and waters containing historic or scientific objects. The same authority supported Bush’s original monument. Critics of recent monument designations argue that such large actions should require Congress, while supporters say the law was designed to permit decisive protection of nationally significant resources.

Hawaii Gov. David Ige endorsed the expansion after seeking assurances about Native Hawaiian participation, research, cultural access and fishing around Kauai and Niihau. [Honolulu Civil Beat reported](https://civilbeat.org/2016/08/ige-backs-marine-monument-expansion/?ref=theamericanquorum.com) that Ige gave his support one day before the proclamation, adding state backing to requests from scientists, conservation groups and Native Hawaiian leaders.

The decision makes Papahānaumokuākea both a conservation project and a governance test. Protecting an ocean area larger than Alaska will require surveillance, enforcement, research and cooperation among NOAA, the Fish and Wildlife Service, Hawaii’s government and the Office of Hawaiian Affairs.

The monument’s remoteness is its greatest protection and one of its greatest vulnerabilities. Few people will see its reefs, seabirds or deep-water corals, and policing a vast ocean boundary is expensive. Yet the scale is also the point: ecosystems, migrations and climate pressures do not conform to narrow rings around islands.

With Friday’s proclamation, the United States has placed a portion of the Pacific comparable in size to a nation beyond commercial extraction. The practical effects on fisheries and enforcement will be debated, but the legal boundary is immediate. Papahānaumokuākea now represents an unusually large wager that preserving ecological systems intact—before their full value is measured—is itself a form of national stewardship.
