Impact of drilling on Wolves

Wolves primarily den in the foothills and mountains south of the coastal plain in the refuge. Wolverines are infrequently observed but travel in all types of arctic terrain, and females may use snowdrifts along small tundra streams for dens. During spring, wolves roam out to the coastal tundra where they prey on newborn caribou. Population declines or changes in distribution of wolves are results PREDICTED from the increased mortality, decreased prey, harassment, and disturbance in denning areas caused by oil development. The cumulative effects of displacement, avoidance, and reduced food resources could result in long-term changes in wolverine distribution. Further information found here.*
