More than a thousand years ago, in the 940s, Europe was a very different place. The Byzantine Empire was at its peak and Vikings sailed the seas. In the midst of it all sat a little sapling, one that would grow into a tree that still thrives today.
According to scientists, a Bosnian pine (Pinus heldreichii) growing in the highlands of northern Greece is more than 1,075 years old, making it the oldest single tree known in Europe.
And it was already about 250 years old when the University of Oxford was founded.
“It is quite remarkable that this large, complex and impressive organism has survived so long in such an inhospitable environment, in a land that has been civilized for over 3,000 years,” said Mr Krusic.
He’s a dendrochronologist – an expert on dating trees.
This one was discovered by a team which included researchers from Stockholm University, the University of Mainz and the University of Arizona.
Studying old trees allows scientists to gain a better understanding of the history of climate change
It is one of more than a dozen individual trees of around that age, living in a forest high in the Pindos Mountains.
