Late winter and early spring in sub-arctic and arctic ecosystems are characterized by high radiation levels and fluctuations between freezing and thawing temperatures. Evergreens are important key species, and the light and UV doses received by evergreens in the late winter and early spring are high due to reflectance from the long-lasting snow cover on to sites without snow. This paper reviews research on light and UV acclimation in the sub-arctic.
