‘An unsettled climate is expected to bring change to the mountains, forests and rivers of the ecosystem. As temperatures warm, fish will move upstream to stay in water that is cold enough for them. The snow line is moving up-slope, and wolverines need to follow, for they need deep snow to raise their young. And important grizzly bear foods such as huckleberries are expected to migrate or disappear, which would mean that bears will need to move as well.’
