Geography and Climate

Location and Topography

Bering Land Bridge National Preserve occupies 2.7 million acres on the in northwestern , within the Northwest Arctic Borough and Nome Census Area. The preserve extends along approximately 67 miles of the Arctic coastline, situated about 55 miles east of the Russian border and 100 miles north of Nome. It lies south of the , with central coordinates near 65°50′N 164°10′W, encompassing remote terrain disconnected from road systems and accessible primarily by , , or snowmachine. The topography consists predominantly of low-relief tundra plains and rolling hills, interspersed with prominent tors—isolated rock outcrops resistant to —and extensive areas. Winding rivers, such as the Kuzitrin and , carve through the landscape, forming valleys and supporting riparian zones amid the otherwise brush-minimal uplands. Coastal features include sandy beaches, barrier islands, and shallow lagoons along the , while inland areas feature thermokarst lakes and polygonal patterns shaped by . Elevations range from to modest hilltops rarely exceeding 1,000 feet, reflecting the subdued glacial and periglacial modification of the underlying . This varied but generally flat facilitates visibility over ridgelines and supports seasonal migrations of across the open expanses.

Climatic Conditions

The Bering Land Bridge National Preserve lies within a zone influenced by its proximity to the and continental interior, featuring long, severe winters and brief, cool summers with significant diurnal and seasonal temperature variations. Coastal areas experience milder conditions due to maritime influences, while the interior exhibits greater extremes in temperature and precipitation. The average annual temperature, based on data from nearby Nome, is approximately 21°F (-6°C). Winters dominate from October to May, with temperatures typically ranging from -10°F to -20°F (-23°C to -29°C), though extremes can plunge to -65°F (-54°C), compounded by strong winds that exacerbate windchill effects. forms along the coast by mid-October and persists until late May, contributing to persistent cold and limited daylight. Snowfall begins as early as in some years, with heavy accumulation from October onward, supporting a that endures into and influences stability across the preserve's landscapes. Summers are short and mild, averaging around 50°F (10°C), though interior areas can reach the mid-60s to 70s°F (15–24°C) or higher on rare occasions. Annual averages about 15 inches (38 cm) near Nome, primarily as in winter and rain in summer, with low evaporation rates fostering moist conditions. Continuous underlies much of the region, shaping hydrology and vegetation, though recent observations indicate thawing trends linked to warmer winters and increased rainfall.

Geology

Geological History

The bedrock of Bering Land Bridge National Preserve primarily consists of Late Proterozoic to early sedimentary, volcanic, and metasedimentary rocks formed along the continental margin of the , including shallow-water miogeoclinal deposits that were subsequently metamorphosed under blueschist-facies conditions during subduction-related events. These protoliths, part of the Nome Complex and related units, underwent polyphase deformation and low- to high-grade , with remnants of ophiolitic sequences—such as basalts, sheeted dikes, , and serpentinized ultramafic rocks—indicating ancient obduction or arc-continent collision along the margin. During the Mesozoic Era, particularly the Brookian Orogeny between 170 and 145 million years ago, the region experienced significant tectonic compression from the collision of the Angayucham volcanic arc with the North American margin, leading to thrust faulting, regional metamorphism, and emplacement of granitic plutons such as the Oonatut Granite Complex (dated 69–80 million years ago). These intrusions, including biotite granites, thermally altered surrounding metamorphic rocks and formed prominent tors through later weathering, as seen in the Serpentine Hot Springs area. The orogeny contributed to the uplift of fault-bounded ranges transecting the peninsula. In the Era, ongoing of the beneath drove further uplift of the and localized volcanism, with the preserve encompassing parts of the Imuruk and Espenberg volcanic fields featuring basaltic lava flows, cinder cones, maars, and pahoehoe flows up to 200 feet thick, some as young as 10,000–20,000 years old. glaciation sculpted the landscape, depositing moraines and exposing , while post-glacial isostatic rebound and sea-level changes influenced surficial features; nearly the entire preserve is underlain by continuous , fostering cryogenic processes like formation and lakes.

Volcanic and Tectonic Features

The Bering Land Bridge National Preserve includes portions of the Imuruk and Espenberg volcanic fields within Alaska's Bering Sea Volcanic Province, where late basaltic magmatism produced diverse extrusive features including lava flows, shield volcanoes, cinder cones, and maars. These eruptions, spanning from the to the , interacted dynamically with thick , leading to phreatomagmatic explosions that excavated large craters. Volcanic activity postdates the Pleistocene glaciation, with the youngest eruptions occurring as recently as 1,000–2,000 years ago. The Imuruk volcanic field dominates the preserve's interior, covering about 900 square miles with roughly 75 vents and forming a basaltic plateau up to 200 feet thick. Key units include the Lost Jim lava flow, which spans 88 square miles with pahoehoe morphology and thicknesses of 10–150 feet, fed by tube systems that caused collapse pits up to 330 feet across upon thawing underlying . The Pleistocene Camille volcanics overlay thinner flows less than 25 feet thick, while the Pliocene-Pleistocene Gosling volcanics feature twin calderas 1,700–2,500 feet in diameter and flows up to 300 feet thick; older Imuruk and Kugruk units are more deeply eroded. In the northern Espenberg volcanic field, five Quaternary shield volcanoes anchor a landscape exceeding 400 square miles, punctuated by the Earth's largest —shallow craters from repetitive steam-driven explosions where 1,000–1,100°C vaporized ice. Devil Mountain Maar, the youngest at approximately 17,500 years old, measures 5 by 3.7 miles across and 328 feet deep; North and South Killeak maars (40,000–50,000 years old) reach 2.5–3 miles long and 80–200 feet deep; Whitefish Lake maar dates to 100,000–200,000 years old at 2.5 miles long. These features, up to 8 kilometers in diameter, fill with lakes and highlight explosive hydrovolcanism unique to periglacial settings. Tectonically, the preserve occupies the stable western margin of the North American craton on the , shaped by the Brookian Orogeny (170–145 million years ago), when collision of the Angayucham oceanic arc with the continental margin folded sedimentary rocks into the Bendeleben Mountains and intruded granite plutons (69–80 million years old) of the Oonatut complex. subduction of Pacific beneath drove regional extension and intraplate , with offshore faults active since the Paleocene-Eocene facilitating basin formation and basalt ascent; ongoing slow seismic deformation reflects minor contemporary rifting.

Serpentine Hot Springs

Serpentine Hot Springs constitutes a geothermal system within Bering Land Bridge National Preserve, featuring two principal thermal zones: Serpentine Hot Springs proper and adjacent Arctic Hot Springs. The springs discharge along fractures in the underlying Oonatut Granite Complex, a Late Cretaceous biotite granite pluton dated to 67-69 million years ago that intruded into older pelitic and mixed schist metamorphic rocks over an area of approximately 70 km². Meteoric water percolates to depths of 2-3 miles through these fractures and contact zones, acquiring heat via convective circulation in a non-magmatic geothermal regime, with subsurface reservoir temperatures estimated at 127 ± 3°C based on chemical geothermometers. isotope ratios (3He/4He = 0.343) confirm the absence of a volcanic or mantle-derived heat source, distinguishing the system from regional volcanic features. The total hydrothermal heat discharge approximates 8 MWt, supporting surface flow temperatures of 35-75°C. Water chemistry classifies as sodium-chloride type, with concentrations of 1430-1480 mg/L chloride, 789-807 mg/L sodium, 78-81 mg/L silica, and 7-8 mg/L fluoride; the fluid exhibits partial seawater influence (approximately 7%) and saturation with respect to calcite and fluorite. The two thermal areas share identical geochemistry, indicating a common deep reservoir. Prominent landscape features include tors—freestanding spires and boulders—resulting from prolonged and exfoliation of the jointed Oonatut , which contrasts with surrounding and exposes the pluton's medium- to coarse-grained texture. These tors, emblematic of the region's tectonic inheritance from the Brookian , encircle the springs and contribute to the area's distinctive morphology without direct influence on the geothermal activity. The hot springs have facilitated archaeological preservation, with stratified deposits yielding fluted projectile points dated to approximately 12,400 calibrated years before present, embedded in geologic contexts predating inundation.

Bering Land Bridge and Migration History

Formation of the Land Bridge

The , often referred to as , emerged as a terrestrial connection between northeastern Asia and northwestern due to eustatic sea-level lowering during Pleistocene glaciations, which exposed the shallow of the Bering-Chukchi platform. This platform, underlying the modern , has an average depth of approximately 50 meters in the region, allowing exposure whenever global sea levels fell below this threshold. The primary driver was the accumulation of vast ice sheets, such as the Laurentide and Cordilleran in and Fennoscandian in , which sequestered ocean water and reduced sea levels by 120–130 meters at the (LGM). Recent paleoceanographic reconstructions, based on sediment cores and from the , indicate that the most recent and prolonged exposure of the began around 35,700 calibrated years (cal yr ), later than earlier estimates that placed initial formation before 40,000 years ago. Prior to this, the strait remained submerged despite broader glacial advances, as regional ocean dynamics and isostatic adjustments delayed the critical sea-level drop in the Bering region. The bridge persisted as dry land until approximately 11,000 cal yr , when post-LGM deglaciation caused rapid sea-level rise, inundating the area and restoring the modern strait configuration. This formation was not a singular event but part of cyclical Pleistocene patterns tied to Milankovitch orbital forcings, with earlier bridges exposed during prior glacial stages (e.g., Marine Isotope Stage 4, ~71,000–57,000 years ago). However, the interval provided the widest and most stable corridor, approximately 1,000 kilometers wide at its peak, facilitating biotic exchanges without significant topographic barriers like the Chukchi Mountains acting as refugia. Geological evidence from subaerial sediments and pollen records confirms the land's unglaciated, steppe-tundra character during exposure, contrasting with surrounding ice-covered regions.

Evidence for Pleistocene Migrations

Archaeological evidence from eastern , encompassing present-day and adjacent regions, indicates human presence by at least 15,000 years ago, contemporaneous with the exposure of the Bering Land Bridge during lowered sea levels of the . Sites such as those in the Valley reveal tools and hearths dated to 14,000–11,000 years (BP), associated with and landscape modification through fire, suggesting adaptation to steppe-tundra environments that extended across . These findings align with faunal remains of Pleistocene megamammals like and , which shared ranges between and , providing indirect support for trans-Beringian movement corridors viable for human dispersal. Genetic analyses of ancient and modern DNA further substantiate a Beringian standstill model, wherein proto-Native American populations diverged from Siberian ancestors and remained isolated on the land bridge or adjacent refugia for 5,000–15,000 years before southward expansion. Mitochondrial DNA haplogroups A, B, C, D, and X, predominant in Native American lineages, trace to northeastern Asian sources around 20,000–15,000 BP, with ancient DNA from Siberian sites like Yana RHS (31,000 BP) showing basal affinities to later American founder populations. A 2019 study of 10,000-year-old Siberian remains identified genetic markers closer to Native Americans than to contemporaneous East Asians, indicating gene flow across Beringia followed by isolation. Y-chromosome data similarly link Native American Q-M3 haplogroups to Central Siberian groups like the Kets, with divergence estimated at 17,000–14,000 BP. Paleoenvironmental reconstructions from cores on the now-submerged Bering Shelf demonstrate habitable conditions during peak exposure (35,000–11,000 BP), with and isotopic records indicating grassy steppes supporting subsistence via and gathering. Warmer, wetter intervals around 14,700–13,900 BP correlate with archaeological signals of dispersal into unglaciated corridors south of the , facilitating rapid by 13,000 BP. While pre-20,000 BP sites like (Yukon Territory, ~24,000 BP) remain debated due to dating ambiguities, the convergence of post-15,000 BP archaeological, genetic, and climatic data robustly evidences Bering Land Bridge-mediated migrations during the .

Debates on Migration Theories

The traditional "Clovis First" model posited that the earliest human migrants to the crossed the from around 13,000 years ago, with distinctive stone tools marking their arrival and rapid dispersal southward. This view, dominant until the late , relied on abundant Clovis sites across but faced challenges from pre-Clovis archaeological evidence, such as the site in dated to approximately 14,500 years ago, which includes non-Clovis artifacts and preserved organic remains indicating human presence before the hypothesized ice-free corridor opened. More recent findings, including human footprints at dated to 21,000–23,000 years ago via radiocarbon analysis of associated seeds, further undermine Clovis primacy, suggesting arrivals during the when the land bridge was exposed but continental ice sheets blocked interior routes. The Beringian Standstill Hypothesis proposes that ancestral Native American populations became genetically isolated in Beringia—a refugium spanning the and adjacent unglaciated regions—for several thousand years (roughly 25,000–15,000 years ago), allowing divergence from Siberian ancestors before southward expansion. Genetic evidence from , including mitochondrial haplogroups A, B, C, D, and X unique to , supports this isolation, as does the recovery of distinct "" genomes from sites like Upward Sun River in (dated ~11,500 years ago), showing basal affinity to modern but separation from East Asian lineages. Critics argue the standstill duration may be overstated, citing and records from eastern Beringia indicating human landscape modification as early as 30,000 years ago, potentially implying earlier or more fluid movements rather than prolonged stasis. Debates persist over migration routes, contrasting an inland path across the deglaciated land bridge with a coastal "kelp highway" involving watercraft along Beringia's Pacific margin. Proponents of the coastal route cite paleoceanographic data showing productive kelp forests and marine resources viable for boat-supported travel as early as 16,000 years ago, bypassing ice barriers and explaining rapid southern sites like Monte Verde without interior corridor evidence before 13,000 years ago. Inland advocates point to archaeological traces in Beringia, such as tools at Swan Point, Alaska (dated ~14,000 years ago), and genetic models favoring terrestrial dispersal post-standstill, though submerged coastal sites due to post-glacial sea-level rise (up to 120 meters) limit direct testing. Hybrid models incorporating both routes gain traction, supported by evidence of early maritime adaptations in Northeast Asia, but lack consensus due to preservation biases favoring inland sites.

Ecology

Flora and Vegetation

The vegetation of Bering Land Bridge National Preserve consists primarily of , characterized by a mosaic of low-growing communities adapted to , short growing seasons, and extreme climatic conditions. This includes sedge- and grass-dominated on moist flats, dry upland with scattered forbs, and shrubby thickets in protected drainages, with exhibiting shallow systems confined to the active layer above for nutrient uptake. Diverse , from coastal plains to inland ridges and river valleys, supports localized variations, enabling dozens of species to coexist in compact areas despite the harsh environment. Graminoids such as sedges (Carex spp.) and grasses form the backbone of tundra cover, providing structural stability and forage, while shrubs including willows (Salix spp.) and dwarf birch (Betula nana and B. glandulosa) dominate in mesic sites and contribute to berry production for wildlife. Berry-bearing shrubs like bog blueberry (Vaccinium uliginosum), lowbush cranberry (Viburnum edule), and crowberry (Empetrum nigrum) are widespread, alongside ericaceous species such as Labrador tea (Rhododendron tomentosum, formerly Ledum palustre) in wet bogs. Non-vascular plants, including mosses, liverworts, and lichens, cover extensive ground, comprising up to 50% of biomass in some lichen-rich tundra patches and serving as key winter forage for ungulates. Wildflowers bloom vibrantly during the brief summer, transforming the landscape with species such as common fireweed (Chamerion angustifolium), which reaches heights of up to 2 meters in disturbed areas; monkshood (Aconitum delphinifolium), a poisonous deep-purple ; and one-flowered cinquefoil (Potentilla uniflora), featuring five-petaled blooms with an orange spot from mid-May to mid-June. Other notable forbs include woolly lousewort (Pedicularis dasystachys), alpine forget-me-not (, Alaska's state flower), Kamchatka rhododendron (Rhododendron camtschaticum), and alpine arnica (Arnica alpina), which favor rocky slopes and alpine meadows. Trees are sparse and stunted due to wind exposure and poor soils, with balsam poplar (), the northernmost North American , occurring mainly in riparian zones along riverbeds where it provides and medicinal resources from its resinous buds and . Recent monitoring indicates increasing shrub cover and height, attributed to regional warming, alongside potential declines in from , , and effects, as measured in permanent plots using laser transects and species inventories.

Fauna and Wildlife Populations

The fauna of Bering Land Bridge National Preserve consists primarily of species adapted to the Arctic tundra and coastal environments, including large mammals that migrate seasonally and numerous avian species that breed in the region during summer. Land mammals such as caribou of the Western Arctic Herd utilize the preserve's grasslands and uplands for calving and foraging, while moose inhabit wetland areas. Grizzly bears, averaging 400-800 pounds for adult males standing up to 7 feet tall, roam widely in search of berries, roots, and prey. Muskox populations, introduced to the in the , persist in the preserve but have declined from higher numbers observed historically, with individuals often seen in family groups grazing on grasses. Wolves prey on caribou and other ungulates, maintaining ecological balance, while smaller mammals like arctic ground squirrels, red foxes, and snowshoe hares occupy burrows and shrublands. numbers on the peninsula stabilized following a decline in the , though their distribution has shifted toward inland areas. Coastal sightings include walruses, , and occasionally or beluga whales, drawn by marine productivity. Over 170 bird species migrate through the preserve annually, utilizing it as a key stopover on the Pacific Flyway and breeding ground for species such as yellow-billed loons, sandhill cranes, and arctic terns. Shorebirds and waterfowl nest in wetlands and along rivers, with raptors like gyrfalcons hunting small mammals. These populations fluctuate with seasonal migrations, peaking in summer when insects and vegetation support breeding.

Notable Ecological Events

Wildfires, though infrequent in the tundra-dominated landscape of Bering Land Bridge National Preserve, represent significant ecological disturbances that alter vegetation structure and nutrient cycling. In 2015, lightning ignited the Tallowpot Fire on July 19 near the mouth of Placer Creek, which expanded to approximately 854 acres, primarily burning shrubland (81.5%) and grassland vegetation. A second lightning-caused fire occurred in the same year, highlighting how episodic dry conditions and thunderstorms can overcome the typical moisture barriers to tundra ignition. These events drive short-term effects such as biomass removal, soil surface darkening, elevated soil temperatures, and deepened thaw layers in permafrost, potentially accelerating organic matter decomposition and releasing stored carbon. Historically, similar fires during the warm, dry summer of 1977 demonstrated fire's role in reshaping tundra communities, though large burns remain rare due to the preserve's wet, organic-rich soils. Seabird die-offs along the preserve's coastal margins have emerged as another key ecological indicator of marine ecosystem stress. Since 2017, local communities and park staff have documented annual incidents of dead and dying seabirds, including thousands of short-tailed shearwaters washing ashore in 2019 near the preserve in the northern Bering and Chukchi Seas. These mass mortality events, persisting into their fifth year by 2019, correlate with marine heatwaves like the 2014-2016 "Blob" phenomenon, which disrupted forage fish availability and food webs supporting species such as common murres and shearwaters. Such die-offs signal broader trophic disruptions in the Bering Sea, where warming alters plankton dynamics and prey distribution, indirectly affecting terrestrial-coastal linkages in the preserve. Unusual weather patterns tied to climate variability have also influenced preserve ecology, including winter rains and ice storms that damage vegetation and alter snowpack insulation over permafrost. These events exacerbate erosion on barrier islands and coastal areas adjacent to the preserve, contributing to habitat loss for nesting birds and marine-dependent species. Overall, such disturbances underscore the preserve's sensitivity to rapid environmental shifts, with fires and die-offs serving as episodic resets that may favor shrub expansion or shift species compositions in response to thawing permafrost and altered hydrology.

Human History and Cultural Aspects

Prehistoric and Indigenous Occupation

Archaeological evidence indicates human occupation of the , encompassing the Bering Land Bridge National Preserve, for at least 12,000 years, with ancestors likely migrating from via the exposed Bering Land Bridge during the . These early inhabitants practiced mobile subsistence hunting and gathering, utilizing natural features such as coastal sites for and inland lakes for caribou and fish. Sites like Cape Espenberg on the northern coast reveal late prehistoric settlements with evidence of adaptations, including house depressions and artifacts linked to Eurasian , such as items dated to around 600-800 years ago, suggesting ongoing trans-Beringian exchanges. The Paleoarctic tradition, evident in northern including the preserve vicinity, dates to approximately 9,000-7,000 years , characterized by microblade tools and adapted to post-glacial environments. Subsequent cultures transitioned to more specialized patterns, with the Birnirk and phases around 1,000-500 years ago introducing bow-and-arrow technology, umiak boats, and semi-subterranean houses for year-round coastal living. These developments reflect adaptations to the region's and ecosystems, with and plant remains from layers confirming vegetated refugia on the as early as 18,000 years ago, supporting human and faunal passage. Indigenous Iñupiaq peoples, descendants of these prehistoric groups, have maintained continuous presence on the , relying on caribou herds, seals, and fish for sustenance until contact in the mid-19th century disrupted traditional patterns through and introduced in 1884. Oral histories and genetic ties link modern communities to Siberian kin, underscoring the area's role as a cultural corridor rather than a mere route. Archaeological surveys document over 100 sites within the preserve, though erosion threatens coastal exposures, highlighting the need for ongoing protection of these records of human resilience in .

Modern Exploration and Settlement

Russian exploration of the , encompassing the Bering Land Bridge National Preserve, began in the mid-18th century following Vitus Bering's voyages, with Russian naval surveys documenting coastal features and Native communities by the 1760s. Fur trading activities, primarily targeting sea otters and foxes, were concentrated along the coasts under the from 1799 onward, but inland penetration into the preserve's interior remained limited due to harsh terrain and reliance on Native intermediaries for pelts. These operations established no permanent non-Native settlements in the remote upland areas, focusing instead on transient trading posts and Native villages. Following the U.S. purchase of in 1867, American whalers and traders extended activities into the region during the 1870s–1880s, introducing in 1892 to supplement Native subsistence amid declining caribou populations; herds peaked at over 500,000 by 1900 but later declined due to and disease. The of 1898–1900 drew thousands to the peninsula's southern beaches, prompting inland prospecting northward into preserve boundaries along streams like the Inmachuk River, where small-scale yielded modest gold recoveries until approximately 1915. Miners constructed temporary cabins and trails, some of which persist as archaeological remnants, but operations were seasonal and abandoned as richer coastal deposits were exhausted, leaving no enduring communities. Throughout the , the preserve area saw negligible non-Native settlement, with human presence dominated by subsistence hunters and herders; the lack of roads and severe climate preserved its isolation until the preserve's establishment in 1980 under the Alaska National Interest Lands Conservation Act. Scientific expeditions, including geological surveys by the U.S. Geological Survey in the early , documented potential but confirmed low viability for large-scale . Today, visitation relies on bush planes, boats, or snowmachines, with no infrastructure supporting permanent residency beyond seasonal Native use.

Establishment and Management

Legislative Establishment

The Bering Land Bridge National Preserve was legislatively established as part of the Alaska National Interest Lands Conservation Act (ANILCA), Public Law 96-487, signed into law by President on December 2, 1980. This act redesignated the prior Bering Land Bridge National Monument—proclaimed in 1978 under the —from monument to preserve status, encompassing approximately 2.457 million acres of federal public lands in northwestern . ANILCA's Title II specifically authorized the preserve to conserve significant geological, biological, and archaeological resources representative of the Pleistocene-era that once connected and , while permitting continued subsistence uses by local rural residents, distinguishing it from stricter protections. The legislation directed the Secretary of the Interior to administer the area through the , emphasizing preservation of evidence of ancient migrations and ecosystems without prohibiting traditional hunting, fishing, and gathering activities essential to indigenous communities. The establishment reflected broader congressional efforts in ANILCA to balance conservation with Alaskan Native subsistence rights and economic interests, amid debates over federal land withdrawals in the state following the of 1971. By designating it a rather than a or , Congress ensured regulated public access for recreation and scientific study, while safeguarding paleontological sites that provide evidence of megafaunal extinctions and human dispersal across .

Administrative Structure

The Bering Land Bridge National Preserve is administered as a unit of the (NPS), which operates under the Department of the Interior and manages over 390 protected areas nationwide. Day-to-day operations are overseen from the park headquarters in , at P.O. Box 220, with contact facilitated through the NPS Alaska Region for regional coordination and support. Superintendent Jeanette Koelsch, appointed in 2009, directs preserve activities, including resource protection, visitor engagement, and collaboration with local stakeholders. The administrative team comprises a small core of permanent staff supplemented by seasonal positions, such as administrative support assistants and resource specialists, to address the preserve's remote location and limited infrastructure. Governance adheres to the Alaska National Interest Lands Conservation Act (ANILCA) of December 2, 1980, which mandates protection of ecosystems, habitats, and cultural sites while authorizing subsistence resource use by qualified rural residents and permitting activities like grazing under regulated conditions. Administration involves interagency cooperation, particularly through the Federal Subsistence Board and the Regional Advisory Council, to balance conservation with traditional practices among Inupiaq communities.

Subsistence Use and Resource Management

Subsistence activities in Bering Land Bridge National Preserve are conducted primarily by Inupiaq residents from neighboring rural communities, who rely on the preserve's resources for food, materials, and cultural continuity, as mandated by the Alaska National Interest Lands Conservation Act (ANILCA) of December 2, 1980, which prioritizes customary and traditional uses by local rural Alaskans on federal public lands. These practices encompass hunting marine mammals such as bowhead and beluga whales using traditional umiaqs (skin boats) and harpoons, with all parts utilized including muktuk (skin and blubber), raw meat, and bones for tools; seal hunting for bearded and ringed species, yielding oil, hides, fur, and fermented flippers; and terrestrial game like caribou, moose, grizzly bears, and muskoxen for meat, hides, and sinew. Fishing targets salmon, Arctic char, grayling, sculpin, and cod through summer nets and traps or winter ice spearing and jigging, with products dried, smoked, or fermented for storage. Bird harvesting includes , geese, swans, ptarmigan, and cranes for meat, supplemented by collection from , terns, and cormorants, while gathering by community members—often women—provides berries (blueberries, salmonberries, crowberries, cranberries) for raw consumption or akutuq ( ice cream mixed with fats), alongside edible greens like leaves, fireweed, , masru ( potato), sourdock, and wild celery for food and medicine. occurs in and near the preserve by local groups, integrating managed herds with wild resource use. Whale harvests involve communal distribution and celebrations, reflecting ongoing cultural ties to ancestral practices spanning thousands of years. Resource management falls under the Federal Subsistence Management Program (FSMP), a multi-agency framework implementing ANILCA Title VIII to ensure sustainable harvest opportunities on , with seasons, bag limits, and methods specified in annual regulations (e.g., 2024-2025 rules effective August 29, 2024). The maintains resource viability for subsistence while balancing other uses, allowing access that supersedes certain restrictions (e.g., off-road vehicle limits during snow cover for travel) and regulating reindeer grazing within defined rights-of-way. Bowhead whaling adheres to quotas set by the , preventing overharvest amid migrating populations funneling through the . These measures prioritize empirical monitoring of wildlife populations and habitat integrity to sustain yields, with subsistence users holding priority over recreational or commercial takes when resources are limited.

Recent Developments

Infrastructure and Visitor Facilities

Access to Bering Land Bridge National Preserve requires charter or from regional hubs such as Nome or Kotzebue, as no roads connect to the 2.7 million-acre unit. The preserve lacks any internal road network, bridges, or vehicular infrastructure, emphasizing its remote, roadless character to preserve ecological integrity. No maintained trails exist within the preserve, compelling hikers and backpackers to navigate off-trail terrain using personal GPS, maps, and self-reliant skills amid tussock tundra, rivers, and varying weather conditions. camping is allowed without permits or designated sites, but visitors must pack out all waste, follow principles, and prepare for limited rescue options due to the area's isolation. Subsistence activities by local communities supplement minimal recreational use, with no developed campgrounds or ranger stations on-site. The primary visitor facility is the Bering Land Bridge Heritage Center in , which provides interpretive exhibits on the preserve's , , and , along with trip-planning resources and bear-resistant storage rentals. In September 2025, the center reopened following nearly a year of renovations to modernize displays and improve accessibility, marking a key upgrade in off-site support for the preserve's limited visitation of under 1,000 annually. Deferred maintenance across park assets, including potential upgrades to remote hot springs access like Serpentine Hot Springs, totals approximately $2.3 million as of fiscal year 2024, focusing on essential repairs rather than expansion.

Conservation and Research Initiatives

The administers Bering Land Bridge National Preserve to safeguard arctic tundra ecosystems, including diverse plant communities and habitats supporting species such as en and caribou. Established under the National Interest Lands Conservation Act of 1980, management emphasizes the preservation of paleontological resources, with enabling legislation mandating their protection and study. In 2024, the U.S. Department of the Interior implemented a rule enhancing fossil protections across public lands, including the preserve, to prevent theft and deterioration. Conservation efforts integrate subsistence practices by local rural residents, permitting hunting, fishing, and trapping under the Federal Subsistence Management Program since at least 2022. Funding from the allocated in 2024-2025 supports collaborations with associated tribes to preserve subsistence traditions. populations, reintroduced in the region, benefit from historical international conservation partnerships, including exchanges with dating back to efforts in the early to restore fauna. A planned restoration project, funded by the NPS and set to commence in 2025, aims to enhance habitats amid ongoing beaver participation events like Beaver Day since 2023. Research initiatives focus on paleoecological reconstruction, with sediment core sampling from the conducted in 2023 aboard the Sikuliaq to infer conditions on the submerged , including and assemblages. The U.S. Geological Survey leads projects identifying prehistoric plant and animal distributions on the , using geological and ecological data to model past as of June 2025. Geospatial studies on caribou residency, incorporating , collect precise location data to inform habitat management on the . Assessments of climate change vulnerabilities target coastal cultural resources, documenting erosion and thaw impacts at sites within the preserve. monitoring via aerial imaging along coastal areas, performed between July 3-12, 2018, supports long-term ecological tracking. Due to resource constraints, no new research permits are accepted for 2025.
