Tree diversity helps reduce heat peaks in forests

A forest with high tree-species diversity is better at buffering heat peaks in summer and cold peaks in winter than a forest with fewer tree species. This is the result of a study led by researchers from the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University, and the Martin Luther University Halle-Wittenberg (MLU). The study was carried out in a large-scale planted forest experiment in China, and has been published in the journal Ecology Letters. It provides yet another argument for diversifying tree species in forests, especially under ongoing climate change.
