High Arctic species populations have decreased by an average of 26% between 1970 and 2004
Sub Arctic species populations peaked in the mid-1980s and have been on the decline ever since
There has been a dramatic decrease in sea-ice extent in the High Arctic; further reduction is expected in the future. Species such as the polar bear, narwhal and ringed seals depend on sea ice for foraging, birthing and predator evasion
