Forests fulfill numerous important functions, and do so particularly well if they have a diversity of trees, according to a new study. As a second study demonstrates, forest managers do not have to decide on the provision of solely one function, such as wood production or nature conservation—several services provided by forest ecosystems can be improved at the same time. Both studies were led by scientists from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv), and published in the prestigious journal Ecology Letters.
