Designer forests: Scientists hope to tune up Canada’s trees to thrive in changing climate

Forest geneticists aim to tune up Canada’s working forests with trees better suited to changing climate conditions and that increase timber yields by up to 30 per cent in the bargain. The $5.8-million project won’t be creating genetically engineered trees, rather the researchers will scour the genes of diverse existing populations of important species such as Douglas fir and lodgepole pine for useful and often highly localized adaptations to heat, cold, drought, snow and rain.  “Trees of the same species from warm places tend to grow longer and faster than trees from colder places, but they might be less cold hardy,” said lead researcher Sally Aitken, a forestry professor at the University of British Columbia. “So there is significant genetic variation between a larch from one place and another.”
