Mountain forests and climate change : impacts and adaptation

Abstract

This review identifies the main impacts of climate change on mountain forests, mainly in Europe, and the management practices proposed for forest adaption. The rise in temperatures, more frequent droughts and the multiplication of extreme events should lead, especially below 1000m in altitude, to the disappearance of highly drought-intolerant tree species (spruce, Scots pine) and their replacement by deciduous trees. In addition, recruitment of some species (fir, beech) is observed at higher altitudes and the duration of the growing season is increasing. Management recommendations for forest adaptation to climate change focus on reducing tree species' vulnerability to water stress and pests, as well as increasing their resilience and ability to respond to extreme weather events. They require genetic improvements and practices that encourage the establishment of suitable species, reduce water consumption and reduce the exposure of stands to risk.
