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 the setting of this experiment with deadwood in the Bavarian Forest National Park: some of the wood is kept in cages to keep insects at bay.
