The grey wolf is fully protected in Sweden and partially controlled in Norway. The Scandinavian wolf populations owe their continued existence to neighbouring Finland's contiguity with the Republic of Karelia, which houses a large population of wolves. Wolves in Finland are protected throughout the country, and can be hunted only with specific permission. The decline in the moose populations has reduced the wolf's food supply.
Since 2011, Netherlands, Belgium and Denmark have also reported wolf sightings presumably by natural migration from adjacent countries. Nonetheless, they are still considered to be extinct in these regions.
In this video, the BBC has traveled to Norway to meet a pack of wolves. In Norway they visit a research station where Tess, a scientist studying wolves takes them in to an enclosure where they encounter wolves face to face, and ends up howling with the pack.
