France's trees are dying at an increasing rate due to disrupted seasonal patterns
Over the past decade, mortality has increased by around 9% for beech and pedunculate oak, by more than 6% for chestnut and by 5.2% for Scots pine. Repeated departures from typical climate conditions have played a major role in the widespread tree die-off observed across France.
The exceptional heat waves of 2026 will "probably" speed up the phenomenon, warn researchers.
A study by the Laboratoire des sciences du climat et de l'environnement reveals a significant increase in the decline of French trees due to climatic anomalies Mortality
According to a study conducted by international researchers, this phenomenon is due to an accumulation of "seasonal climatic anomalies".
French forests are experiencing an unprecedented increase in the natural mortality of trees between 2015 and 2023. A study published this Thursday in Nature Communications shows that the accumulation of seasonal climatic anomalies is permanently weakening many species across the country.
An international team led by the Laboratoire des sciences du climat et de l'environnement and the Swiss WSL Institute has established that several common species die up to four times as many as ten years ago in French forests, according to a study published on 9 July 2026 in Nature Communications. This decline, long on the account of heat waves alone, hides a more insidious mechanism. The mortality of trees is due less to an isolated extreme eve…
