Un pin de 1 230 ans
Oldest European Tree Found—And It’s Having a Growth Spurt

A craggy pine tree growing in southern Italy is 1,230 years old, making it the oldest tree in Europe that has been scientifically dated.
Moreover, the ancient pine seems to be living it up in its old age, researchers reported last week in the journal Ecology. Examinations show that the tree had a growth spurt in recent decades, where larger rings were added to its trunk even though many trees in the Mediterranean region have been experiencing a decline in growth.
The discovery shows that some trees can survive for centuries even when subjected to extreme changes in climate. This ancient pine, for example, would have germinated in a cold period during Medieval times and then lived through much warmer temperatures, including periods of drought.

Analysing its growth through so many years of shifting conditions can help scientists better understand how forests at large might respond to modern climate change, the study team says.
