In the mountain areas in the interior, reindeer can be seen (these have Sami owners), hunted by the indigenous wolverine. There are also a few brown bears in the interior. The Arctic fox is now in danger of extinction on the mainland, but a few are left in these mountain areas, particularly in Børgefjell mountains. Red foxes, moose, hares, squirrels, small rodents, pine marten (inland valleys) and stoats are all common in the forests. As of 2008, there were a minimum of 50 lynx in Nordland residing in the forests in all Nordland except Lofoten and Vesterålen. In lowland areas, roe deers now occur in most of Nordland, and red deers are seen in the southern part of Nordland. The badger and the common viper has their most northerly habitat in southerly coastal areas of Nordland. Grey wolves have been observed in inland areas of Helgeland. There are few species of amphibians, although the common frog is common in all Nordland except mountain areas, and the smooth newt has its most northerly habitat in the world in the river Vefsna. There are seven national parks in, or partly in, Nordland. From south to north, these are Børgefjell National Park, Lomsdal-Visten National Park, Saltfjellet-Svartisen National Park, Junkerdal National Park, Rago National Park, Sjunkhatten National Park and Møysalen National Park. The national park centre for Nordland is situated in Saltdal.
