In recent years, high temperatures combined with poorly distributed rainfall and a lack of water have led to droughts, with a major impact on tree growth and life. 

Very occasionally violent winds and storms cause a great deal of damage in several regions of  France. Solid precipitation, such as hail, snow and late frost, causes damage or limits tree growth or flowering.

With the regular droughts, the forests are drying out and the potential for fires is increasing, even in regions where there were previously few fires. 

With forests more fragile and weakened by drought, more and more pests such as bark beetles and fungi are spreading at high speed, sometimes decimating entire forests.
