Sometimes you need construction skills to do scientific experiments! 🔨 Last autumn, Anna Lintunen and her colleagues built massive roof structures near Hyytiälä forestry field station. They studied how the snow cover on the ground, or actually the lack of one, affects trees. 🌨️ 🌲 There will likely be less snow in southern Finland in the future. This affects trees, since snow functions as an isolation layer between the ground and the air. When there is no snow cover, the ground may freeze deeper down during winter. This may cause frost damage to tree roots or hinder the growth or water absorption of trees in the spring. Anna’s team does measurements both under the roof structures and in the nearby woods, where the snow cover is normal. Anna is currently analysing the data together with postdoc researcher Lauri Lindfors. The experiment continues next winter, so let’s wish for another snowy one!
