An international research team has now determined the annual contribution made by deadwood to the global carbon cycle and quantified the importance of insects in the decomposition of wood for the first time. - Here you can see deadwood in the beech forest near the ecological station of the University of Würzburg. Fungi have set about decomposing the logs.
