Fossil reversal

Located near Canada's Baffin Island, Bylot Island (1st image, aerial view) is home to a forest that flourished between 2.6 and 3 million years ago. By analyzing pollen samples from the mummified trees in the permafrost (2nd image, slideshow here), Alexandre Guertin-Pasquier of the University of Montreal has reconstructed which species will sprout up again within the next 100 years when conditions warm due to climate change. "The fossil forest found in Bylot Island probably looked like the ones actually found in the [present-day] south of Alaska, where tree-line boreal forest grows near some glacier margins. The main plant diversity also seems to be similar between these two environments." The reawakened forest will include oak, willow, pine, spruce, and hickory trees, and will shed light on how they managed to survive the dark arctic winters and other mysteries.
