French trees near 'rupture threshold' as heatwaves intensify

France's forests are facing unprecedented challenges as recurring heatwaves push some tree species towards a critical tipping point. While the forest ecosystem is not uniformly affected, specific types of trees are exhibiting significant signs of distress under the strain of extreme heat.

The ash tree, particularly in the southwestern regions of France, has been identified as highly vulnerable. These trees are reportedly nearing their hydraulic rupture threshold, a point beyond which their ability to transport water is severely compromised, leading to potential dieback or death.

Experts are closely monitoring the situation, with the upcoming month of July expected to be decisive. The weather patterns during this period will play a crucial role in assessing the overall resilience of French forests and understanding the long-term consequences of these exceptional heat episodes on the nation's arboreal landscape.
