Species-rich forests better compensate environmental impacts

To offset CO2 emissions, China is reforesting. Much more carbon could be stored, if a mixture of tree species instead of monocultures were planted. An international team including UZH researchers has shown that species-rich forest ecosystems take up more CO2 from the atmosphere and store more carbon in biomass and soil, making them more effective against climate change.

This research was carried out by an international collaboration. Among them were SPSW members Bernhard Schmid and Pascal Niklaus with their teams at the Department of Evolutionary Biology and Environmental Studies of the University of Zurich.
