Dating works have focused on studying the perimeter of tree trunks 50 centimeters of soil and laser telemetry, has lifted the section has allowed for specific calculations to determine the age of the tree.
A method that has been used as an alternative to other methods such as carbon 14 or measuring the growth rings, not been possible to implement this project.
The work was sponsored by the Bank Santander Foundation at the request of the Commonwealth of the Taula del Sénia.
