Giuggiola, A., Kuster, T.M., Saha, S., 2010. Drought-induced mortality of Scots pines at the southern limits of its distribution in Europe: Causes and consequences. IForest 3: 95-97
Several severe drought events have been reported in southern Europe during recent decades. Drought has been found to increase the mortality of the southernmost populations of Scots pine forests in Mediterranean countries and in dry inner-alpine valleys. Therefore the ongoing global climate change is likely to endanger Scots pine in future decades. Carbon starvation might be the main cause of the increasing mortality rate due to less carbon uptake and consequently to high susceptibility to biotic attacks. Forest management, in particular, thinning and shrub removal could decrease the intensity of drought stress by decreasing competition for water resources and thus increasing carbon uptake. The ongoing climate change and adaptive forest management will both play an important role for the sustainability of this specie across southern regions of Europe.
