Did you know snow acts like a winter blanket for the soil?
By insulating the ground from cold air temperatures, snow helps protect soil structure, plant roots, and the microorganisms that keep ecosystems functioning. When snow cover is reduced, soils can experience repeated freeze-thaw cycles that may damage soil health and impact carbon storage.
Researchers in Wisconsin are studying how changing winter conditions affect forests and soils by warming experimental plots and manipulating snow cover. Using sensors that measure soil temperature, moisture, snow depth, and soil respiration, they are working to understand whether soils will continue storing carbon or release more of it into the atmosphere.
What happens beneath the snow has lasting impacts on our forests, agriculture, and climate. Understanding these changes today helps us prepare for the future.
