…changes in climate are expected to drive wildlife seeking refuge up mountains and further north. But for trees… the changes in climate are often coming too fast to get out of the way, especially when combined with pressures from logging, said Suzanne Simard, a professor in the University of British Columbia’s Faculty of Forestry. …In a new study published in Global Change Biology, Simard and her UBC colleagues took three-year-old interior Douglas fir seedlings from locations in southern B.C. and planted them as far north as Fort St. James, the northern limit of the species’ range … to find out how the trees would handle the human-assisted migration, and if they would do better in a colder climate. …As early as 2006, University of Alberta researcher Andreas Hamann published a study that concluded climate change could push the range of B.C.’s tree species north at a rate of 100 kilometres per decade.
