Aitken and collaborators talking to the Verge about climate change and forests

Whitebark pines are majestic trees with a whitish, often wind-curled trunk that grow up high in the Rocky and Sierra Mountains, in the Western US. They’re icons of Yellowstone National Park, where they provide high-calorie seeds for many animals, including grizzly bears that eat the seeds before hibernating. Some whitebark pines manage to live for a thousand years, but many of them are now dying.

Sally Aitken & Tongli Wang on the future of BC’s forests in BC Business

It soon became evident, though, that climate change is outpacing this gradual approach, and in 2012 the ministry launched another program, dubbed “climate-based seed transfer,” which involves a total overhaul of the province’s approach to reforestation. Rather than determine where a seedling can be planted according to lines of latitude and longitude on a map, decisions will be made according to anticipated climates of the future. The climate-based approach to reforestation will be implemented starting in 2017.

As B.C. moves into uncharted territory in forest management, the whole province can be seen as a giant petri dish, with the provincial government directing the experiment. And we’ve only got one chance to get it right. Unlike a high-school genetics experiment, where students might observe successive generations of flowering plants over the course of a year, trees take anywhere from 50 to 100 years to reach maturity. If the trees we plant today prove unsuited to the climate of tomorrow, there’s no do-over.
