The QuestionHow is climate change research shaping Canadian forestry policy?
BackgroundScientists are finding evidence that climate change has already impacted Canada’s vast forest regions. Shifts in climate are making forests vulnerable to attack by insects such as eastern spruce budworm and the mountain pine beetle, and to more frequent and more devastating fires. Forests are generally understood to absorb carbon from the atmosphere. By reducing atmospheric carbon they appear to offset sources of carbon from industry and elsewhere. But forests are not just carbon sinks, they are also potential sources of atmospheric carbon, especially as they become prone to frequent forest fires. Climate researchers are trying to model the contributions of forests to global carbon budgets. One hypothesis emerging is that young, managed forests absorb more carbon from the atmosphere than old growth forests. And yet, forest carbon dynamics are still not fully understood. Given that forest carbon budgets are difficult to model, researchers have not yet achieved a consensus on how or whether to include forest carbon stocks in global atmospheric carbon budgets. These uncertainties make it difficult to rely on forest carbon models alone when developing sound forest policy. Indeed, if these models dictated forest policy, governments would promote cutting down old growth forests and replacing them with managed forests. See below for more information.
Your Letter to Federal Scientists and Ministers
Dear Scientists,
Climate change poses a real threat to the health of Canadian forests and we are grateful that federal scientists are conducting research on this issue. We are also pleased to see that the Canadian Forest Service provides information to the public on its website outlining how its research programs are responding to climate change. One video explains how climate models and carbon budgets are being used as the basis for developing Canadian forestry policy. These models suggest that young, managed forests may be better carbon sinks than mature, old growth forests. The implication however is a forestry policy that promotes harvesting old growth forests and replacing them with managed forests. While climate change is undeniable, available climate models and modeling techniques are plagued with uncertainty.
How do your findings account for the ongoing debates in the climate modeling literature around best practices for the inclusion of forests in global carbon budgets? Are there uncertainties in your data or models that might cast doubt on a policy that promotes managed forests over protecting old growth forests? In other words, are these carbon budget models reliable enough to be used as the basis for forestry policy, especially when they appear to promote a policy of increased resource extraction from Canadian forests?
Such a managed forest policy seems to contradict well-established scientific evidence on the role of old growth forests in maintaining biodiversity, plant and animal habitat, water and nutrient cycling, and soil stability. In that regard, do you feel that the full range of your research, and the research of your colleagues, is being considered in formation of Canada’s forestry policy? In this case, are climate models and carbon budgets being used uncritically by the government to promote industry-friendly policies?
I am writing this email as part of Write2Know (http://write2know.ca) a letter-writing campaign that aims to mobilize public awareness and inquiry into federal research programs. We want to let you know that we value federal science and scientists, and that our questions arise out of genuine concerns about the health and well-being of Canadians.
We remain concerned about the legacy of constraints on access to federal scientists and the results of their research, the elimination of essential research programs, and the closure of libraries and archives. These constraints and closures have impacted what Canadians can and cannot know about the health of their bodies, communities, and environments. We are hopeful that a new government will address our concerns.
I look forward to your response.
Sincerely,
