Biodiversity does not always improve resistance of forest ecosystems to drought

30 septiembre 2014

The resistance of forests to drought has been studied, with a focus on the diversity of tree species. This study shows that mixed species forests are more resistant to drought stress than monocultures in some regions only: tree diversity may afford resistance to drought stress only in drought-prone areas, i.e. in regions where the frequency and severity of drought during the growing season is high.
