Question: Which is largest national park in world?

Northeast Greenland National Park


Northeast Greenland National Park (Greenlandic: Kalaallit Nunaanni nuna eqqissisimatitaq, Danish: Grønlands Nationalpark) is the world's largest national park and the 9th largest protected land area.[1] Established in 1974 and expanded to its present size in 1988, it protects 972,000km2 (375,000sqmi)[2] of the interior and northeastern coast of Greenland and is bigger than all but twenty-nine countries in the world. It was the first national park to be created in the Kingdom of Denmark and remains Greenland's only national park.
Geography
The park shares borders, largely laid out as straight lines, with the Sermersooq municipality in the south and with the Avannaata municipality in the west along the 45° West meridian on the ice cap in the west. The large interior of the park is part of the Greenland Ice Sheet, but there are also large ice-free areas along the coast and on Peary Land in the north. Besides Peary land, the park includes the King Frederick VIII Land and King Christian X Land geographical areas.
The area is subject to larger loss of ice than expected.[3]
History

Originally created on 22 May 1974 from the northern, practically uninhabited part of the former Ittoqqortoormiit Municipality in Tunu (East Greenland), in 1988 the park was expanded by another 272,000km2 (105,019.8sqmi) to its present size, adding the northeastern part of the former county of Avannaa (North Greenland). In January 1977 it was designated an international biosphere reserve. The park is overseen by the Greenland Department of Environment and Nature. The historical research camps on the ice sheet−Eismitte and North Ice−fall within the boundaries of the present-day park.
Population

The park has no permanent human population. In 1986, the permanent population of the park was 40, living at Mestersvig, although 400 sites saw occasional summertime use. These 40 were involved in cleanup and closeout operations at mining exploration sites and soon left. Since then censuses have recorded zero permanent human population. Recently only 31 people and about 110 dogs were present over winter in North East Greenland, distributed among the following stations (all on the coast, except Summit Camp):[4][5]
Daneborg (12) headquarters of the Sirius Patrol, the park policing agency
Danmarkshavn (8) civilian weather station
Station Nord (5) military base
Mestersvig (2) military outpost with 1,800 m gravel runway
Zackenberg (0) summer-only research station
Summit Camp (4) research station on the Greenland Ice Sheet
During summer scientists add to these numbers. The research station ZERO (Zackenberg Ecological Research Operations)  can cater for over 20 scientists and station personnel.
Fauna

An estimated 5,000 to 15,000 musk oxen, as well as numerous polar bears and walrus, can be found near the coastal regions of the park. This was claimed to be 40% of the world population of musk ox in 2008.[6] Other mammals include Arctic fox, stoat, collared lemming and Arctic hare. Other marine mammals include ringed seal, bearded seal, harp seal and hooded seal as well as narwhal and Beluga whale.
Species of birds which breed in the park include great northern diver, barnacle goose, pink-footed goose, common eider, king eider, gyrfalcon, snowy owl, sanderling, ptarmigan and raven.
