Gran Abuelo: The Possible Oldest Tree on Earth
Written on
Chapter 1: The Mystery of Gran Abuelo
The Gran Abuelo, located in Chile, is believed to be the world’s oldest tree, with estimates suggesting it has been alive for over 5,000 years! However, this claim is still awaiting official verification of its age.
This well-known phrase, "We were gone, there was a forest; we will be gone, there will be a forest," serves as a poignant reminder of the longevity of trees. Many species take years, even decades, to reach impressive heights.
Section 1.1: The Oldest Tree in the World
Trees are not merely natural monuments; they stand as silent witnesses to the passage of time. Scientists have long debated where the oldest tree actually resides. Some believe the venerable title belongs to the Patagonian cypress in Chile, estimated to be around 5,400 years old. This remarkable tree, located in Alerce Costero National Park, boasts a diameter of nearly 4 meters. Although it has not yet been officially recognized as the oldest, it is affectionately known by the Spanish name Gran Abuelo, translating to "great-grandfather."
Section 1.2: Scientific Investigations
Chilean scientist Jonathan Barichivich, associated with the Laboratory of Climate and Environmental Sciences in Paris, estimates the Gran Abuelo to be 5,484 years old. If accurate, this would make it significantly older than Methuselah, a well-known pine in California that holds the current title of the oldest tree at 4,853 years.
Chapter 2: The Challenges of Age Verification
Scientists explore one of the oldest living trees in Chile, revealing insights into its remarkable age and significance.
Section 2.1: Controversial Measurements
Determining the age of a tree is often accomplished through counting the rings of its trunk, a process known as dendrochronology. For living trees, researchers typically extract core samples. Unfortunately, due to Gran Abuelo's extensive width and fragile roots, standard carbon dating methods were not viable. As a result, Barichivich had to employ alternative techniques.
Through core sampling, they discovered 2,400 rings. By analyzing samples from other trees, they developed a statistical model that indicated an 80 percent likelihood that this iconic Patagonian cypress has existed for over 5,000 years.

Section 2.2: The Need for Protection
Currently, the dendrology community remains skeptical about the findings presented by Barichivich and his colleague Lara. Their research has yet to be published in a scientific journal, with findings only shared at academic conferences. Verification of these calculations would be crucial for the protection of the cypress. The influx of tourists to Alerce Costero National Park poses a threat to the tree, as visitors often climb its massive roots, disrupting its water absorption. Furthermore, the region faces challenges due to its dry climate and limited rainfall.
Ultimately, only thorough examination and endorsement by other experts will determine whether Gran Abuelo is indeed nearly 6,000 years old and deserves recognition as the oldest tree in the world.
