134:(or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Ed Cook from Columbia University has stated "The only way to truly determine the age of a tree is by dendrochronologically counting the rings and that requires all rings being present or accounted for".

Milenario tree is covered with lichens and mosses. It is estimated to have over 5000 rings. If accurate, that would be more than 100 years older than the current record holder. Barichivich said

The Alerce
Milenario Tree is located in a ravine, in the Alerce Coster National Park. The park is 137 hectares (340 acres), and up to 1,048 m (3,438 ft) above sea level. It has a rainy temperate climate with rains all year round. Its average temperature is 12°C (53°F). The park receives

However, the method dendrochronology comes with challenges, primarily due to the need to examine the internal of a tree. This can cause damage, and the borers used can be insufficient for the width of some trees, particularly older species where the internal core is damaged or rotten. Jonathan
145:
The method has so far yielded evidence of approximately 2400 growth rings, but because the borer used could not reach the center of the tree, modelling was used to predict an overall age estimate of more than 5,000 years with 80% certainty.
154:
It is hoped the findings of the age of the tree will lead Chile's government to better protect it. Chile's
National Forest Corporation has stated it has increased protections for the tree, and added rangers to the park.
