Forest Tree Responses to a Changing Climate

Spicer, Rachel [1].

Forest Trees in a Changing Climate.

This symposium will focus on the impact, both measured and modeled, of climate change on forest tree physiology as it pertains to forest health and tree mortality. Coverage will include work conducted at scales ranging from organism to ecosystem, with molecular and cellular processes often embedded within organismal or population-level observations (e.g., cellular respiration as fundamental to carbohydrate storage and resource allocation; gene flow as fundamental to local adaptation). Although the focus will be on woody plants in North American forests and chaparral, efforts will be made to place the work in a global context. Discussion will also extend to the management implications of predicted forest tree responses, including uncertainty associated with these predictions. Alberta is an ideal location for a symposium on this topic because forest health and productivity are central to both the Canadian economy and natural environment. Invited speakers include scientists studying the role of cavitation − which in extreme cases can lead to tree death − in response to a warmer, drier climate. Other speakers will focus on long term trends in aspen dieback, large-scale population monitoring, and predicted phenological responses to changes in the length of the growing season. All of these areas integrate physiological phenomena with measured and/or predicted changes in species distributions in response to climate change. Lastly, a large and highly publicized trial of forest tree “assisted migration” is taking place in British Columbia. This proactive approach is controversial, raising significant questions about risk assessment and whether deliberate movement of species might do more harm than good (see “Forestry: Planting the forest of the future” Nature 459, 906-908 (2009) [http://www.nature.com/news/2009/090617/full/459906a.html]). We are fortunate to have a lead researcher on this project participating in this symposium, as this work represents an important interface between ecophysiology, adaptation, and management practices. We expect lively discussion to follow this series of presentations, which will integrate relevant issues in basic physiology, population biology, and forest management.
