GC11F:
Dynamics, Drivers, and Impacts of Vegetation Change in Boreal and Arctic Ecosystems I Posters


Session ID#: 7880

Session Description:
Multiple lines of evidence suggest that the Arctic is “greening” in response to climate warming and wetting, while parts of the Boreal may be “browning”. Yet, substantial uncertainties exist regarding the rate, magnitude, causes and implications of this vegetation change.

This session seeks to integrate diverse research on the dynamics, drivers, and consequences of vegetation change in terrestrial, high-latitude ecosystems with the ultimate goal of better predicting how the vegetative cover change will feedback to the climate system. We are especially interested in submissions that investigate the biogeochemical, biophysical, and other ecosystem-level consequences of vegetation change. In addition, we encourage submissions that develop a mechanistic understanding of the causes of vegetation change. We also welcome submissions that document the dynamics of ongoing vegetation change, including (but not limited to) studies that utilize remote sensing and repeat photography.
