TORONTO, January 19, 2012 – Invasive alien species are on the move in response to a warming climate but Canadian policies designed to manage the problem rarely consider how climate change is ratcheting up the risk, according to York University research published today in the journal Environmental Reviews.
“The interactive effects of climate change and invasive species are expected to have profound consequences for environments, economies and societies worldwide, says lead author Andrea Smith (pictured). “For example, many new infectious diseases will likely spread to theArctic, and coordinated circumpolar disease monitoring and targeted healthcare planning will be needed to handle this new pressure. Yet, these two drivers of global change are rarely considered jointly in policy and management initiatives.”
Smith, now a postdoctoral fellow in the Department of Biology atYorkUniversity, conducted the research review while a senior fellow atYork’s Institute for Research and Innovation in Sustainability (IRIS). She and eightYorkUniversityco-authors in fields ranging from science to law and social science to business, reviewed published research on invasive species shifting distributions under climate change to identify gaps in knowledge and research inCanada. Their comprehensive, interdisciplinary review finds that research has tended to focus on predictions of how climate change will affect the distribution of existing invasive species in Canada (including mountain pine beetle, gypsy moth, smallmouth bass and Lyme Disease), rather than on potential invasive species that might expand their range into Canada. Existing research also tends to ignore the socio-economic dimensions of the problem, they found.
There are barriers to predicting changes in the invasive species’ range under climate change, including the complexity of the issue, lack of ecological data, and failure to address the interactions between climate change and invasive species in research and policy. However, scientific knowledge about the impact of climate change on invasive species is growing, Smith says, and can be used as the foundation for policy development.
“This is just another example of how climate change is a big threat multiplier,” notes John P. Smol, editor of Environmental Reviews and professor at Queen’s University where he also holds the Canada Research Chair in Environmental Change. “We simply have not even begun to understand all the negative repercussions of this problem.” This synthesis is the first to characterize the current state of knowledge on this critical issue inCanada.
Smith is now conducting a legislative review of invasive species policy in Canada, for the Ontario Ministry of Natural Resources and the Canadian Aquatic Invasive Species Network.
