among the areas in the world with most seabirds, with about 20 million individuals during late summer. The most common are: little auk, northern fulmar, thick-billed murre, and black-legged kittiwake. Sixteen species are on the IUCN Red List. Particularly Bjørnøya, Storfjorden, Nordvest-Spitsbergen, and Hopen are important breeding ground for seabirds. The Arctic tern has the furthest migration, all the way to Antarctica. Two songbirds migrate to Svalbard to breed: the snow bunting and the northern wheatear. Rock ptarmigan is the only bird to overwinter. Remains of Predator X (Pliosaurus funkei) from the Jurassic period were discovered here. It is one of the largest dinosaur-era marine reptiles ever found. Svalbard has permafrost and tundra, including low, middle, and high Arctic vegetation. One hundred and sixty-five species of plants have been found on the archipelago. Only those areas which defrost in the summer are vegetated, which accounts for about 10% of the archipelago. Vegetation is most abundant in Nordenskiöld Land, around Isfjorden and where affected by guano. While there is little precipitation, giving the archipelago a steppe climate, plants still have good access to water because the cold climate reduces evaporation. The growing season is very short, and may last only a few weeks. The Svalbard poppy (Papaver dahlianum) is the symbolic flower of Svalbard. There are seven national parks in Svalbard: Forlandet, Indre Wijdefjorden, Nordenskiöld Land, Nordre Isfjorden Land, Nordvest-Spitsbergen, Sassen-Bünsow Land and Sør-Spitsbergen. The archipelago has fifteen bird sanctuaries, one geotopic protected area and six nature reserves—with Nordaust-Svalbard and Søraust-Svalbard both being larger than any of the national parks. Most of the nature reserves and three of the national parks were created in 1973, with the remaining areas gaining protection in the 2000s. All human traces dating from before 1946 are automatically protected. The protected areas make up 65% of the archipelago. Svalbard is on Norway's tentative list for nomination as a UNESCO World Heritage Site. The total solar eclipse of 20 March 2015 included only Svalbard and the Faroe Islands in the band of totality. Education Longyearbyen School serves ages 6–18. It is the primary/secondary school in the northernmost location on Earth. Once pupils reach ages 16 or 17, most families move to mainland Norway. Barentsburg has its own school serving the Russian community; by 2014 it had three teachers, and its welfare funds had declined. A primary school served the community of Pyramiden in the pre-1998 period. There
