Northeast us population density map4/17/2024 ![]() The main population is within the areas of semi-domestic reindeer husbandry in the northern parts of the country. The minimum population was 50-80 animals during the 1980s. Finnish wolverines probably reached a minimum population level before receiving protection in 1982. The population, as revealed by hunting statistics, showed a steady decline from before the turn of this century, when about 50 individuals were killed annually, to less than half the numbers around 1930. FinlandĪs in the other Fennoscandian countries, wolverines were historically persecuted in Finland. This population is isolated from the larger population in northern Norway by 100-200 km. Reports indicate increasing geographical distribution and numbers in southcentral Norway during recent years. The 1995-97 population was estimated to consist of a minimum of 30 individuals. Wolverines were hunted to functional extinction in southern Norway, where the species received protection in 1973, but recolonized the Snøhetta plateau in southcentral Norway in the late 1970’s. Today wolverines are found mainly in mountainous areas in south-central Norway and along the Norwegian-Swedish border from Hedmark county northwards. The species was, until the beginning of this century, distributed throughout most of the forested and mountain areas as far south as the southernmost counties of Norway. The population seems to be stable, although limited and restricted local control actions were introduced in 1996. Based on records of active natal dens during 1995-97, the population was estimated at a minimum of 265 individuals in all of Sweden, with almost 200 of these in the northernmost county (Norrbotten). The population has increased since protection. ![]() At that time, wolverines were limited to a small population in the mountain areas along the Swedish-Norwegian border. The hunting statistics indicate that the population declined steeply from about 1870 until they received protection in 1969. Reproducing populations also existed in the boreal forest areas even as far south as Dalarna and Värmland counties in southern Sweden. ![]() (2000) SwedenĪt the beginning of the last century, wolverines were found at relatively high densities in the mountainous parts of central and northern Sweden. The following summaries of the wolverine’s distribution in Europe are excerpted from Landa et al. Present populations are found only in the central to northern parts of Norway, Sweden, Finland and Russia mainly north of latitude 60° N (Landa et al. Historically, the distribution of wolverines included areas as far south as all Norway, the southern parts of Sweden, Estonia, Lithuania, and northeast Poland. The wolverine’s worldwide presence (fundamental niche) is congruent with the distribution of persistent spring snow cover and may reflect adaptations toward elevated thermal avoidance (Copeland et al. It is generally found south to 37 degrees north in North America and 50 degrees north in Eurasia (Pasitschniak-Arts and Larivière 1995, Copeland and Whitman 2003). 1988 from Pasitschniak-Arts and Larivière 1995). ![]() The wolverine has a circumpolar distribution (click to view PDF) that corresponds with the boreal zone of the northern hemisphere, occurring throughout arctic and subarctic regions and boreal forests of Eurasia and western North America (Kvam et al. ![]()
