Chilean environmental scientist Jonathan Baričivić has recently made a splash in the dendrochronology community
Baricevic is well “familiar” with the tree.He grew up in the area around the park, with both his parents working there as caretakers. It was only recently that he began to study wood seriously. His job involved taking a non-destructive core sample to count the tree's growth rings, the gold standard for determining its age. However, the drill bit was too short to penetrate the center of the wood. Thus, the scientist received only approximate data.
However, he collected samples from other, youngertrees of the same type growing nearby. The researcher then used statistical modeling to make a guess about the age of the tree. He obtained the modeling information from core data from Alerce Milenario and other core samples, as well as environmental data. The model was then used to estimate the number of missing rings that were likely formed in the inner parts of the nucleus. According to it, the tree is probably 5,484 years old and appeared before our era. Now the oldest tree is officially considered to be the bristlecone pine, which grows in California. Research has shown that she is 4,853 years old.
Barichivich calls this tree Gran Abuelo(great-grandfather) and plans to continue studying its features. He admits more work is needed to confirm its age, including obtaining a complete core sample. He is now trying to convince the government to take action to protect the tree.
