Winter Wonderland? Climate, Carbon, Forests with Ecologist John Campbell, Part of Cold is Cool Series
Climate change is altering forests in complex ways, with outcomes that are difficult to predict. Adding to this complexity are simultaneous changes in multiple interacting factors such as air pollution, invasive species, and land use. Our knowledge of the effects of climate change during winter is especially poor, and recent investigations have begun to focus on this topic. An integrative winter monitoring and research program at the Hubbard Brook Experimental Forest near Woodstock, New Hampshire is shedding light on the importance of ecological processes during winter. This information is contributing to a more complete understanding of climate change impacts on forests and effects on carbon storage. Long-term data from Hubbard Brook and the broader Northeast region document changes in winter climate, such as the loss of extreme cold air temperatures, a decline in the depth of the snowpack, and reduction in the duration of ice cover on lakes. Shorter-term winter manipulation experiments are providing insight about the impacts of extreme events like ice storms and soil freeze-thaw events. Winter not only affects forests, but also shapes the character of New England and helps drive the economy, especially in rural northern communities. This presentation will explore and facilitate discussion about observed changes in winter climate, the impacts of those changes, how we are adapting, and what the future holds.

John Campbell is a Research Ecologist with the US Forest Service in Durham, NH. His work unit manages the Hubbard Brook Experimental Forest where he is involved in maintaining the long-term records of climate and hydrology. His research focuses on ecological processes in forest watersheds that affect water quality and quantity, with an emphasis on impacts of changing winter conditions. His work includes analyses of long-term data, shorter-term field experiments, laboratory studies and computer modeling, and has been performed at multiple scales ranging from small plots to global syntheses. The goal of his research is to understand ecosystem responses to natural and human-caused disturbances to help inform land management decisions and policies.
