Spain is a tourism monster, and one of the most visited points is Teide. The territory of the volcano is imposing, and Bárbol hides on one of its slopes. As the character of ‘The Lord of the Rings‘, Treebeard, a Canary Islands cedar that was the oldest living tree in the European Union. And we say “was” because it has just been surpassed by one of its own species.
One that is estimated to be 1,544 years old.
Clonal or non-clonal, that is the question. Before we get into the discovery, let’s clarify an important concept when talking about the oldest living trees. There are two categories main: clonal and non-clonal. And understanding them is quite simple:
- A non-clonal tree is an individual, the traditional concept of a tree that grows from a seed. It is a unique individual with its root system and a main trunk.
- A clonal tree is one that is born from a root system. For example, some roots can give rise to a tree that grows and dies, and from those same roots, another tree is then born, being a “clone” of the original.
Another Canary cedar. Found by researchers from the School of Forestry, Agronomic and Bioengineering Industry Engineering at the Duques de Soria Campus and by experts from the University Institute of Sustainable Forest Management at the University of Valladolid, the newly discovered specimen is a whopping 1,544 years old and is, like Bárbol, a Canary Islands cedar. He overcomes it by several years, since esteem that Bárbol is 1,481 years old, and fortunately for these two specimens, they are very far from tourist areas and human influence.
This has allowed them to spend a millennium and a half in the same place where they were born, without worrying about the deforestation of the area caused by humans, and they have not been affected by the eruptions of the volcano. To access the new specimen, the researchers had to be assisted by local climbers to access these remote areas of the Teide National Park to be able to take the samples.
This is how they found Treebeard
Importance. Thus, they have been able to carry out an inventory of ancient cedars located in these areas that are difficult to access. Of the 25 specimens analyzed with the carbon 14 techniquethe existence of eight millennia has been evidenced, three of them exceeding 1,500 years. They are the witness of an ancient population of cedars that would have covered a large part of the park.
The team has commented that it is one of the most important concentrations of ancient trees in the European Union and, furthermore, that “its persistence is due to the inaccessibility of the rocks in which they live.” Lucky.
Its scientific value is also enormous, since it is like a historical record of the climate. Studying rings of ancient trees allows us to reconstruct the climatic history of the region, obtaining data on rainfall and drought patterns, tracing an evolution of temperatures and, in the case of Teide, identifying the frequency of volcanic events.
It all depends on the “portage”. Those responsible for this discovery are the same ones who already dated to Treebeard in 2022, and it must be said that in Finland they found a juniper with a century more on its bark. Baptized as Utsjoki, in a first analysis in 2021 it was given 1,242 years, but after the discovery of Bárbol, they repeated the analysis and they found with which he was many more: 1,647 years old.
But since technicalities have their importance in these things, it must be said that… everyone is right in stating that “theirs” is the longest-lived. The difference is in the arboreal habit of each subject. Both are non-clonal, but while the Finnish juniper had a bushy appearance, the canary has an arboreal appearance.
And… well, it must also be said that the juniper died in 1906, so the two canaries are the longest living trees.

Legends. It is evident that there is a “competition” to find the oldest tree, but this is not a race to turn it into something touristy, as if it can happen with other finds, but rather to have new specimens that allow us to obtain a historical x-ray of the land on which they are.
Apart from the specimens studied with methods such as carbon 14 belonging to this classification of non-clonal trees, we have specimens such as Old Tjikko Swedish 9,560 years old. The “trap” is that it is a clonal specimen, so the root system is almost 10,000 years old, but the trunks that appear from time to time only last a few centuries.
And finally, those that belong to “folklore”, such as the yew Llangernyw in Wales which, located in the cemetery of a church, is estimated to be about 5,000 years old or the yew tree Fortingall in Scotland between 3,000 and 9,000 years old. Too wide a range.
