Description
Temperatures in the Arctic and alpine regions have risen twice as fast as the global average. Climate models predict that this trend will continue, particularly in winter, leading to a reduction in snow cover. Snow cover plays a key role in the functioning of cold climate and mountain ecosystems, as its presence strongly influences surface energy fluxes and biological and chemical processes in the soil. Snow cover buffers soil and plant temperatures, limits water loss, reduces the exposure to freeze-thaw cycles, and improves soil and plant water status after spring snowmelt. Conversely, snow can limit the length of the plant growing season. Due to global change, mountain regions are facing rapid reductions in snow cover, but the effects on woody species are still not well known. This session brings together researchers working on the influence of changes in snow cover on various plant traits, including plant phenology, growth, and hydraulics.
Format/Concept
Building on the insights from our focus group session on the impacts of climate change on forests, this upcoming session will explore the effects of reduced snow depth and duration on plant life. We invite participants who are passionate about understanding these changes and those who wish to share their findings from snow manipulation experiments conducted in various mountain regions. Let’s come together to explore, discuss, and learn from each other’s experiences.
