Antarctic Conservation Act — Protection of Antarctic Wildlife and Ecosystems

The Antarctic Conservation Act of 1978 (16 U.S.C. §§ 2401–2413), administered by the National Science Foundation (NSF), prohibits U.S. citizens and U.S.-flag vessels from taking native Antarctic wildlife, entering protected areas, or introducing non-indigenous species into Antarctica without a permit. It implements the Antarctic Treaty and its Protocol on Environmental Protection (the Madrid Protocol), which designates Antarctica as a natural reserve devoted to peace and science. NSF — not NOAA or FWS — administers the Act because virtually all U.S. Antarctic activity passes through NSF's U.S. Antarctic Program (USAP), which operates three research stations (McMurdo, Amundsen-Scott South Pole, and Palmer) and manages the supply chain of science projects, personnel, and logistics across the continent.

Current Rule (2026)

What This Rule Does

The Antarctic Conservation Act and its implementing regulations establish a permit-based system protecting Antarctica's native wildlife and ecosystems from the impact of human activity — primarily scientific research programs, tourism, and fishing operations. The regulations apply to any U.S. citizen, any person in the U.S., and any person aboard a U.S.-flag vessel in or near Antarctic waters.

The core prohibition is broad: it is unlawful to take any native Antarctic mammal, bird, plant, or invertebrate (where "take" includes capture, handling, killing, disruption, or collection); to engage in harmful interference with these species; to enter an Antarctic Specially Protected Area (ASPA) without authorization; to import or export native Antarctic species; or to introduce non-indigenous plants or animals into Antarctica — all without a permit. The only significant exceptions are emergencies threatening human life, prior possession before October 28, 1978, and controlled introduction of non-living food animals.

The only species currently designated as "Specially Protected" under the Act is the Ross Seal (Ommatophoca rossii) — an Antarctic ice seal that is not endangered but whose populations and behavior are so poorly understood that the Antarctic Treaty Parties designated it for heightened protection. Permits to take Ross Seals may be issued only for "compelling scientific purposes" that won't jeopardize survival of the species.

Key Provisions

• § 670.2 — Scope: covers all U.S. citizens and U.S.-flag vessels regardless of where in Antarctica the activity occurs; extraterritorial jurisdiction is the norm for Antarctic Treaty obligations
• § 670.4 — Prohibited acts: taking or harmful interference with native mammals, birds, plants, or invertebrates; entry into ASPAs without authorization; receiving, acquiring, transporting, or possessing native species taken in violation of the Act; importing into or exporting native species from the United States without a permit; introducing non-indigenous species
• § 670.5 — Emergency exception: the prohibitions do not apply when the actor reasonably believed the act was committed under emergency circumstances involving the safety of human life or of ships, aircraft, or high-value equipment; also covers aiding or salvaging native mammals or birds in distress
• § 670.7 — Food introduction exception: non-living animals and plants may be introduced as food under carefully controlled conditions; unconsumed poultry or its parts must be removed from Antarctica or incinerated, autoclaved, or otherwise sterilized before disposal — preventing disease introduction from domestic poultry to Antarctic bird populations
• § 670.12–670.14 — Permit criteria and conditions: NSF's Director may issue permits after public comment; permits must further the purposes of the Act; each permit may contain terms and conditions appropriate to its authorized activity; permits must be carried by the holder during authorized activities
• § 670.17 — Specific criteria for taking native species: permits to take (capture, handle, or collect) native mammals, birds, plants, or invertebrates may only be issued for (a) scientific specimens; (b) zoological exhibitions or educational purposes; (c) information needed to manage activities under the Act; permits must be limited to the minimum take necessary; NSF must find the activity will not cause significant adverse impact
• §§ 670.20–670.22 — Designated native species: Subpart D lists designated native birds (penguins, petrels, albatrosses, skuas, terns, etc.), native plants (all plants with range including Antarctica — bryophytes, lichens, fungi, vascular plants), and native invertebrates (mites, nematodes, rotifers, springtails, tardigrades)
• § 670.25 — Specially Protected Species: the Ross Seal is the sole specially protected species; taking requires a permit issued only upon a finding of compelling scientific purpose and that the taking won't jeopardize species survival
• § 670.40–670.42 — Antarctic Specially Protected Areas (ASPAs): entry requires a permit; permit criteria include the purpose of entry (scientific, monitoring, or management), the ASPA's management plan, and whether proposed activities are compatible with the plan; ASPA management plans are adopted by the Antarctic Treaty Parties under the Protocol
• §§ 670.43–670.44 — Non-indigenous species (Subpart H): introducing live non-indigenous species into Antarctica (animals, plants, microorganisms not native to Antarctica) requires a permit; permit holders must take precautions to prevent unintended introductions (soil on equipment, seeds in food packaging, live bait)

How It Affects You

If you're a U.S. scientist deploying to Antarctica: NSF's Office of Polar Programs administers the U.S. Antarctic Program and coordinates permits for researchers. Most USAP-funded scientists are covered by umbrella or programmatic permits issued to their expedition or station rather than individual permits — but you're still personally bound by the Act's prohibitions. Before you handle any wildlife, collect biological specimens, enter an ASPA, or introduce any materials, confirm with your NSF program officer that the activity is covered. Permit applications go through usap.gov and should be initiated months before deployment. Violations — including accidental ones — are subject to civil penalties up to $5,000 per incident.

If you're an Antarctic tour operator or expedition company: IAATO membership and compliance with its protocols satisfies most U.S. permit requirements for standard tourism activities (wildlife viewing from a safe distance, ship-based operations). The most common permit trigger is landing near or entering an ASPA — many high-traffic sites like Cape Royds (home to the world's southernmost Adélie penguin colony) are partially ASPA-protected. Shore landings in those zones require advance authorization. Failure to hold required permits can result in vessel detention and operator debarment from future Antarctic operations.

If you're a private expedition or adventure traveler: U.S. citizens are bound by the Act even if they travel to Antarctica on non-U.S. vessels or without NSF support. You cannot pick up a rock penguin feather, disturb a seal, or take any biological material without a permit. The practical enforcement risk is low in remote areas, but violations are strict-liability offenses — intent is not a defense for most prohibited acts.

If you're importing Antarctic biological specimens: Any import of Antarctic native mammals, birds, plants, or invertebrates (including parts or derivatives) requires an NSF permit, even for research specimens returning to a U.S. university lab. The permits must accompany specimens through U.S. Customs. Antarctic seawater, sediment cores, ice cores, and geological specimens don't require wildlife permits but may require biosafety clearances from USDA APHIS or CDC depending on the origin and content.

If you're a museum or zoological institution: Display of Antarctic native species (live or preserved) acquired after October 28, 1978 without a permit is a violation. If your institution has historical Antarctic collections, verify the acquisition date and whether an import permit was obtained. NSF can issue permits for zoological exhibitions and educational displays.

Legal Authority

The Antarctic Conservation Act of 1978, Pub. L. 95-541, 16 U.S.C. §§ 2401–2413, implements U.S. obligations under the Antarctic Treaty (1959) and the Protocol on Environmental Protection to the Antarctic Treaty (Madrid Protocol, 1991). Congress delegated permitting and regulatory authority exclusively to NSF rather than EPA, NOAA, or FWS because NSF already operated the entire U.S. governmental presence in Antarctica through the U.S. Antarctic Program (USAP). The Act was amended in 1996 (Pub. L. 104-227) to implement the Madrid Protocol, which elevated Antarctica to the status of a "natural reserve devoted to peace and science" and imposed a comprehensive environmental-protection regime.

The Act's extraterritorial reach is explicit: it applies to any U.S. citizen anywhere in Antarctica and to any person aboard a U.S.-flag vessel operating in Antarctic waters — a jurisdictional hook rooted in the nationality principle of international law and in the U.S. commitment to enforce Antarctic Treaty obligations.

Key Mechanics

Permit system: NSF's Office of Polar Programs (OPP) issues permits for all regulated activities. There is no automatic exemption for government agencies — even DoD logistics flights supporting McMurdo must comply. NSF typically issues umbrella or programmatic permits for recurring activities under the U.S. Antarctic Program rather than individual permits for each scientist.

ASPA entry authorization: Entry into any of Antarctica's 75+ Antarctic Specially Protected Areas requires a permit specifying the purpose, duration, and conditions of entry. ASPA management plans are adopted by the Antarctic Treaty Consultative Meeting (ATCM) and incorporated by reference into 45 CFR Part 670.

ATCM alignment: NSF must periodically update 45 CFR Part 670 to reflect decisions of the annual ATCM — new ASPAs, revised management plans, species reclassifications. The 2021 rulemaking (86 FR 27988) is an example of this housekeeping function.

Enforcement: NSF's Office of Inspector General handles enforcement. Civil penalties: up to $5,000 per violation ($10,000 for knowing violations), subject to periodic inflation adjustment under the Federal Civil Penalties Inflation Adjustment Act (28 U.S.C. § 2461 note). Criminal violations (willful taking of specially protected species, deliberate introduction of invasive organisms) may be referred to DOJ.

Coordination with international regimes: The Act works in concert with other laws for activities that also fall under the Marine Mammal Protection Act (16 U.S.C. §§ 1361 et seq.) or Convention on International Trade in Endangered Species (CITES) when Antarctic species enter commercial trade. NSF coordinates with NOAA Fisheries and FWS on overlapping jurisdiction questions. The Lacey Act provides an additional layer: it prohibits import, export, or commerce in wildlife taken in violation of any federal, state, or foreign law — which means specimens taken in violation of the ACA can also trigger Lacey Act liability when they cross U.S. borders.

Statutory Authority

• 16 U.S.C. § 2401 — Findings and purposes: Congress found that the Antarctic environment and its dependent and associated ecosystems are "deserving of protection" and that the U.S. has a direct interest in protecting Antarctica from harmful human activities; the U.S. has conducted mostly scientific work there for more than 25 years, tourist interest is growing, and NSF leads U.S. efforts to protect Antarctica's unique values
• 16 U.S.C. § 2402 — Definitions: defines key terms including "Antarctica" (area south of 60° south latitude), "harmful interference" (disturbance or damage to birds, seals, native plants, or habitats, including by aircraft, vehicles, or explosives), "take" (kill, injure, capture, handle, molest native mammals or birds, or remove or damage native plants), "import" (land or bring anything into any place under U.S. jurisdiction, including the 12-mile territorial sea, even if customs would not call it an import), and "native species" categories
• 16 U.S.C. § 2403 — Prohibited acts: prohibits bringing banned products onto Antarctic land/ice, dumping waste on ice-free land or into fresh water, incinerating waste in the open, using vessels not covered by anti-pollution standards, harming historic sites, and resisting enforcement officers; without a permit: prohibits disposing waste, introducing non-native species, entering ASPAs, taking or harming wildlife or plants, and buying/selling/transporting native animals or plants illegally taken
• 16 U.S.C. § 2403a — Environmental impact assessment: federal agencies must use NEPA rules to check environmental effects of their activities in Antarctica; requires initial environmental evaluation unless impact is less than minor or short-lived; if more than minor impact is possible, requires a full public comprehensive environmental evaluation

Pending Legislation

• H.R. 5948 (117th Congress, Rep. Beyer [D-VA-8]) — Antarctic Science and Conservation Modernization Act: would implement (1) Measure 4 (2004) requiring insurance and contingency planning for Antarctic tourism and non-governmental expeditions, including civil penalties up to $25,000 per knowing violation; and (2) Annex VI to the Madrid Protocol on liability for environmental emergencies, including strict liability for nongovernmental operators, liability caps pegged to Special Drawing Rights (1 million SDR for vessels under 2,000 tons; 3 million SDR for non-vessel incidents), and insurance requirements. Status: Referred to Subcommittee on Water, Oceans, and Wildlife (117th Congress — did not advance to enactment; no companion bill introduced in 118th or 119th Congress as of May 2026).
• Pub. L. 104-227 (1996) — Antarctic Science, Tourism, and Conservation Act of 1996: the last major ACA amendment; implemented the Madrid Protocol; sponsored by Rep. Walker (R-PA-16); this is the most recent enacted legislation directly amending the ACA.

Recent Rulemakings

86 FR 27988 (May 2021) — Revised the list of designated native birds in § 670.20 and updated the inventory of Antarctic Specially Protected Areas to align with changes adopted by the Antarctic Treaty Consultative Meeting. These updates periodically incorporate decisions of the Antarctic Treaty System — which meets annually to designate new ASPAs, revise management plans, and list newly recognized native species.

No major rulemaking since 2021. The Antarctic Conservation Act framework has been stable for decades; the significant policy decisions happen at the Antarctic Treaty Consultative Meetings (ATCMs), with NSF then updating the regulations to incorporate ATCM decisions.

Pending Action

No major legislative changes to the Antarctic Conservation Act are pending in the 119th Congress (2025–2026). The framework has been stable since the 1996 amendments that incorporated the Madrid Protocol. Policy evolution in the Antarctic arena happens primarily through:

• Annual ATCM decisions: The Antarctic Treaty Consultative Meeting (held in 2025 in Seville, Spain) adopts new ASPA designations and management plan revisions that NSF must incorporate via rulemaking. Watch the Federal Register for follow-on rulemakings updating 45 CFR Part 670.
• Tourism pressure: Antarctic tourism has grown significantly — more than 100,000 visitors per season as of 2024–2025. NGOs and some Treaty Parties have pushed for stricter limits on large-vessel tourism and enhanced ASPA buffers around high-traffic penguin colonies. Any resulting Treaty-level decisions could require NSF regulatory action.
• Climate-driven species shifts: As sea ice patterns change, some Antarctic bird species are expanding or contracting their ranges. This could trigger future rulemakings updating the § 670.20 designated native bird list.
• NSF budget pressures: Congress periodically debates U.S. Antarctic Program funding. Significant USAP funding cuts could affect permit-processing capacity at OPP, though the regulatory framework itself would not change.

State Variations

None. The Antarctic Conservation Act is exclusively federal — there are no state-level analogs or permitting requirements for Antarctic activities. The Act's extraterritorial reach means that even state-chartered research institutions must comply with federal permit requirements for any Antarctic activities.
