The National Petroleum Reserve in Alaska, a sprawling expanse of tundra and wetlands covering nearly 23 million acres, is more than just a site for potential oil extraction. Despite its industrial moniker, the National Petroleum Reserve-Alaska (NPR-A) serves as a crucial habitat for wildlife and plays a vital role in the health of our planet.
Yet, this fragile ecosystem faces significant threats due to new development plans announced by the Trump administration on June 17, 2025. The proposal aims to open up nearly 82% of this remarkable landscape to oil and gas operations, jeopardizing some of its most ecologically sensitive regions. The government is currently accepting public comments on this proposal until July 1, raising concerns among environmentalists and local communities.
The NPR-A was originally established in 1923 by President Warren Harding to serve as an emergency oil supply for the U.S. Navy. However, its management was later transferred to the Department of Interior through the Naval Petroleum Reserves Production Act in the 1970s. This act mandates that while energy development can occur, the Secretary of the Interior must prioritize the maximum protection of the area’s significant ecological, recreational, and cultural values.
Now, the Bureau of Land Management is tasked with overseeing the reserve and safeguarding “special areas” of notable ecological or cultural importance within it. Under the new plans, the Trump administration seeks to expand the land available for drilling from about 11.7 million acres to over 18.5 million acres, which includes parts of these specially designated areas.
One of the most compelling reasons for protecting the NPR-A is its importance for wildlife. The reserve is a sanctuary for Arctic species, including caribou populations that have shown significant declines in recent years globally.
The NPR-A provides critical habitats for three of the four caribou herds on Alaska’s North Slope. These herds experience some of the longest overland migrations on Earth. Any disruption from infrastructure such as roads and industrial activities could severely compromise their health and movement.
The reserve is also crucial for migratory birds. Situated at the northern end of five major flyways, the NPR-A attracts birds from across the globe, including all 50 U.S. states. Remarkably, it hosts some of the highest densities of breeding shorebirds anywhere in the world, with a staggering 72% of Arctic Coastal Plain shorebirds nesting here, totaling over 4.5 million birds.
Among them is the yellow-billed loon, the largest loon species, which breeds primarily in the reserve. The expansion of oil and gas operations in the NPR-A could pose a serious threat to these migratory birds by disrupting their habitats and introducing noise pollution to the area.
A variety of other species also rely heavily on the intact ecosystems within the reserve. Polar bears use these lands to build dens, making it crucial for the survival of their cubs. Wolverines, which follow caribou herds, require large, connected expanses of undisturbed habitat for their dens and food sources. Similarly, moose can be found browsing along the Colville River, the largest river on the North Slope, while birds of prey, such as peregrine falcons and gyrfalcons, nest in the cliffs above.
Currently, a significant stretch of the Colville River is designated as a protected special area, but the proposed plan could strip away these important protections. Areas like Teshekpuk Lake, vital for both caribou and migrating birds, also face the potential loss of their protective status.
The Indigenous communities in the Arctic, particularly the Iñupiat people, depend on the rich natural resources of the NPR-A for subsistence hunting and fishing. Their cultural identity, food security, and spiritual practices are deeply tied to the health of this ecosystem.
However, oil and gas drilling brings extensive risks that can extend far beyond the immediate drill sites. The vastness of the NPR-A means that not every area will undergo drilling, but the lasting impacts are far-reaching. Infrastructure developments such as roads, pipelines, and gravel pads contribute to landscape fragmentation and degradation.
These changes can alter water flow and affect ice melt timing, leading to negative consequences for wildlife that depend on large, connected habitats for their life cycles. The ice roads used in winter for exploration and construction can affect thawing patterns, thereby disrupting natural systems and making it more difficult for shorebirds to nest successfully.
The Willow drilling project, approved by the Biden administration in 2023, serves as a case study illustrating potential impacts. The initial project plan included extensive infrastructure, such as 575 miles of ice roads for construction, a new airstrip, over 300 miles of pipeline, and various drilling sites. Such developments threaten to further reduce wildlife habitats and alter animal behavior.
Animals, including caribou mothers with calves, tend to avoid infrastructure, and studies show that these negative impacts do not diminish over time. Furthermore, in places like Prudhoe Bay, where the largest U.S. oilfield is located, decades of development have resulted in pollution, habitat loss, and myriad environmental issues, including numerous oil spills and extensive permafrost thaw.
This situation emphasizes that the oil drilling footprint is not solely confined to drilling sites but radiates outward, undermining the ecological integrity of the region. The thawing permafrost is now also undermining the stability of the oil industry’s infrastructure.
The climate implications of the NPR-A are also significant. The region plays an outsized role in global climate regulation, where vast reserves of climate-warming carbon are currently locked in the wetlands and permafrost of the tundra.
Unfortunately, the Arctic is warming at nearly three times the global average. The proposed development projects risk accelerating permafrost thaw and coastline erosion, further releasing carbon that has been stored underground for ages. Additionally, the drilling itself would contribute to increased carbon dioxide emissions, adding to global warming.
As the public comment period for this significant and controversial plan approaches its deadline on July 1, the futures of the Arctic and one of the last remaining wild ecosystems in the United States hang in the balance. The decisions made today will undeniably impact the landscape for generations to come.
