Naternaq

Naternaq, also known by its Danish name Lersletten, is one of the most important wetland complexes in western Greenland. Located in the Qeqertalik municipality at coordinates 68°24'N 51°46'W, this vast Ramsar Site encompasses 191,000 hectares of pristine Arctic wetland habitat. The site comprises an extensive marshy plain characterized by numerous shallow lakes, meandering streams, and scattered rocky outcrops of ancient Precambrian basement rocks. Designated as Ramsar Site number 385 in January 1988, Naternaq represents a critical sanctuary for internationally significant populations of waterfowl and serves as one of six Ramsar wetlands in the region, highlighting its exceptional ecological value in the Arctic landscape.

Naternaq supports a remarkable diversity of Arctic wildlife, with particular significance for waterfowl conservation. The wetland is critically important for the nationally endangered Greenland white-fronted goose, historically supporting up to 9% of the breeding and moulting population, though current figures indicate approximately 1.8% of the population uses the site. The extensive wetlands provide essential foraging and nesting habitat for numerous wader species and other geese during the brief Arctic summer. Long-tailed ducks, classified as globally threatened, utilize the site's shallow lakes and streams. Marine mammals including the globally threatened fin whale occur in adjacent waters. The diverse mosaic of habitats also supports caribou populations, which rely on the surrounding tundra for grazing, while Arctic foxes, snow hares, and lemmings inhabit the terrestrial ecosystems.

The flora of Naternaq reflects the extreme Arctic conditions while supporting surprisingly diverse plant communities across its varied microhabitats. Dense moss mats carpet much of the marshy plains, providing crucial moisture retention and insulation for the permafrost beneath. Extensive marshes dominated by sedges and cotton grasses flourish in waterlogged areas around the numerous shallow lakes and along stream margins. Dwarf scrub heath communities, consisting of dwarf willow, Arctic blueberry, crowberry, and Labrador tea, colonize the better-drained slopes of rocky hills. The lush vegetation represents one of the more productive plant communities in western Greenland, supporting the diverse wildlife that depends on this Arctic oasis. Lichens encrust the exposed Precambrian rocks, adding splashes of color to the otherwise muted tundra palette.

Naternaq occupies a fascinating geological setting where ancient basement rocks meet relatively young glacial deposits. The area lies at the northern margin of the Nagssugtoqidian orogen, a major Precambrian geological province. The prominent Naternaq supracrustal belt extends at least 25 kilometers in length and up to approximately 2 kilometers in width, occurring along the northwestern margin of the Lersletten plain. This supracrustal sequence is bordered on both sides by Archaean orthogneisses and granitic rocks dating back over 2.5 billion years. The extensive Quaternary outwash plain that characterizes most of the wetland consists of light grey, silty sediments deposited by glacial meltwater during the retreat of the Greenland Ice Sheet. Scattered low hills with outcrops of crystalline Precambrian basement rocks protrude through the outwash plain, creating the distinctive landscape mosaic.

Naternaq experiences a harsh Arctic maritime climate moderated slightly by the proximity to Disko Bay and the West Greenland Current. Winters are long and severe, with temperatures regularly dropping below minus 20 degrees Celsius and polar darkness lasting for several months. The brief summer season from June to August brings continuous daylight and temperatures that occasionally reach 10 to 15 degrees Celsius, triggering explosive growth in the wetland vegetation. Annual precipitation is relatively low, typically between 200 and 400 millimeters, falling primarily as snow. Strong katabatic winds descend from the nearby Greenland Ice Sheet, while coastal winds from Disko Bay bring moisture and fog. The short growing season of approximately three months constrains plant productivity, but the 24-hour daylight compensates somewhat for the compressed timeframe.

The Naternaq region has been part of the Inuit cultural landscape for millennia, though the wetland itself lacks permanent human settlements due to its marshy terrain. Thule Inuit ancestors migrated into Greenland approximately 4,500 years ago, and subsequent generations utilized coastal areas around Disko Bay for hunting and fishing. The name Naternaq derives from Kalaallisut, the Greenlandic Inuit language, while the Danish colonial name Lersletten translates roughly to 'clay plain.' Indigenous peoples have long recognized the ecological richness of wetland areas for hunting caribou and muskoxen on surrounding uplands, and for harvesting waterfowl eggs and birds during summer. Traditional subsistence practices continue to this day, with the local Greenlandic population maintaining cultural connections to the land while adapting to modern conservation frameworks that protect the site's international ecological significance.

Naternaq gained formal international recognition and protection on January 27, 1988, when it was designated as Ramsar Site number 385 under the Convention on Wetlands. This designation acknowledged the wetland's outstanding importance for waterfowl, particularly as breeding and moulting habitat for the Greenland white-fronted goose. The site represents one of six Ramsar wetlands in the broader West Greenland region, reflecting Denmark's commitment to conserving critical Arctic ecosystems within its autonomous territory of Greenland. Additional legal protections classify Naternaq as an Area Important to Wildlife and a Breeding Bird Reserve under Greenlandic law. The Kommune Qeqertalik municipal government now oversees land-use planning that incorporates these conservation designations, ensuring that development pressures do not compromise the ecological integrity of this internationally significant wetland.

Naternaq remains one of the most remote and pristine wetland areas in Greenland, offering exceptional opportunities for wilderness experiences and wildlife observation. No formal trail system exists within the vast 191,000-hectare site, preserving its untouched character. Visitors willing to undertake the challenging journey can observe spectacular concentrations of Arctic waterfowl during summer months, including the rare Greenland white-fronted goose. The scenic landscape of meandering streams, shallow lakes, and ancient rocky outcrops provides stunning panoramic views of the Arctic wilderness. Kayaking along the interconnected waterways offers intimate access to wildlife habitats while minimizing ecological disturbance. The nearby town of Qasigiannguit, located 52 kilometers away, serves as the nearest jumping-off point for expeditions. Aasiaat, 56 kilometers distant, offers additional logistics support and scheduled flights from Kangerlussuaq.

As an undeveloped wilderness area, Naternaq offers no visitor facilities, accommodation, or infrastructure within its boundaries. Access requires careful logistical planning and typically involves charter boats or helicopters from nearby settlements. The nearest town, Qasigiannguit, lies approximately 52 kilometers away and offers basic amenities including guesthouses and a small airport with connections to regional hubs. Aasiaat, the larger of the two nearby towns at 56 kilometers distance, provides more extensive services including hotels, restaurants, and regular flights from Kangerlussuaq international airport. Visitors must be entirely self-sufficient, carrying all food, shelter, and emergency equipment. The optimal visiting season spans July through August when ice conditions permit boat access and wildlife activity peaks. Local tour operators in Qasigiannguit and Aasiaat can arrange guided expeditions with experienced Arctic guides familiar with the terrain and wildlife.

Conservation of Naternaq faces both traditional and emerging challenges in the changing Arctic environment. Current threats include subsistence and leisure hunting, fishing pressure, and increasing recreational activities such as hiking, kayaking, and establishment of vacation huts around the periphery. Climate change represents a growing concern as warming temperatures alter hydrology, accelerate permafrost thaw, and potentially shift vegetation communities and wildlife distributions. The Ramsar designation provides an international framework for wetland conservation, requiring Denmark and Greenland to maintain the ecological character of the site. Greenlandic authorities balance traditional subsistence rights of Indigenous peoples with conservation imperatives through carefully managed hunting regulations and seasonal restrictions in sensitive breeding areas. The absence of permanent settlements within the site boundary helps preserve its ecological integrity, while ongoing monitoring tracks population trends of key species including the Greenland white-fronted goose.
