Weathering Climate Change

How long before we can expect to see palm trees lining Vancouver boulevards?

It’s expected that shifts in climate will see trees normally associated with warmer climes finding comfort levels farther north. The Vancouver Sun reports here that according to a new study called Climate Projections for Metro Vancouver, “changes in temperature and precipitation will affect everything from sewage pipes to ski hills.” Local trees will be poorly adapted to the rising temperatures and elevated disease pressures.

According to Genome British Columbia, foresters have three options for dealing with climate change: reforest with the same species but with trees that are better adapted to warmer climates; move species further north or to higher elevations; or select and breed trees that can better withstand climatic stresses or disease. This news release from Genone British Columbia is an interesting read. We’re told the CoAdapTree project, which involves revolutionary testing by a genomics research team at UBC led by Dr. Sally Aitken, Forest & Conservation Sciences, will ultimately lead to better reforestation strategies for western Canada’s changing climates.

Climate change isn’t just bad for trees. It’s also bad for the economic and environmental benefits they provide to Canada – benefits like wood, jobs, habitat protection, and carbon sequestration. CoAdapTree: Healthy trees for future climates, will provide recommendations for climate-based seed transfer policy to guide foresters in planting trees that will be healthy in new climates in western Canada. Climate-based seed transfer can result in up to 30% greater timber yields, with a proportional impact on the economy and employment, and will also sustain ecological and environmental benefits of forests.
