We knew that the olive trees were very old trees. What we did not imagine is that they arrived at 4,000 years of age
The olive tree is undoubtedly one of the most iconic trees in the Mediterranean basin. The olive groves have populated the fields of southern Europe and the Levante since time immemorial, but such is the longevity of this species that the history of some of these trees also goes back, at least to antiquity. An example of this is the Vauves olivelocated on the Greek island of Crete. Conservative estimates throw this tree about 2,000 years. This would imply that in his life he could be a mute witness of events such as the division of the Roman Empire, the fall of Biscay and the Ottoman Empire and, of course, the birth of contemporary Greece. Broader estimates calculate that this tree could reach 4,000 years of age. This would not only do it contemporary of figures such as Pythagoras, Aristotle or Alexander the Great but also implied that this plant was born in the Crete Minoica and it was Witness of the collapse of the late bronze ageone of the most intriguing events that occurred at the dawn of history as and how we understand it. But perhaps the most surprising detail of all this is that the olive tree of Vouves continues to bear fruit. This has led many to wonder, how is it possible? What makes this specimen already its species in general so long? The olive tree (Olea Europea) has a life expectancy that, although it does not become ancient, does exceed several centuries. It is estimated that the life expectancy of the trees of this species Round the five centuriesalthough there is some debate about it. In this sense, A study published in 2021 In the magazine Dendrochronologyestimated that the majority of “monumental olive trees” had maximum ages that ranged between 300 and 500 years. Estimating the age of an olive tree is difficult. We indicated at the beginning that the estimates of the age of this millenary tree ranged between 2,000 and 4,000 years, a very wide fork precisely because of the difficulty that involves calculating the age of these trees. Dendrocronology is based on using the growth rings of tree trunks to estimate their age: how many rings, so many years. Counting rings in a carved copy is simple, but doing it in a living tree and doing it in an olive tree is already another song. The trunks of the olive trees grow irregularly, which implies a seemingly chaotic pattern in the rings inside, making the count especially difficult as pointed out A study published in 2013 In the magazine Plos One. His curious growth could be related to his longevity. According to Scott Travers, Biologist at Rutgers University, In an article for Forbesone of the “Secrets” behind longevity of these trees is in vegetative or clonal reproduction. That is, in the fact that this tree consists of various cuttings that start from the same root. This, adds Travers, allows this type of plants to survive extreme conditions, including similar fires, cuts and incidents. Another of the tricks for survival, Continue explaining traversIt is in the biochemistry of the tree, which offers mechanisms that allow repairing damaged tissues, as well as defending against pathogenic organisms. The same oil that humans take advantage of by the tree that gives us through its fruits. The elders of our environment Spain also has ancient olive trees, although we do want to find a tree that competes in age with the olive tree of vouves, we have to go to Portugal. It would be an olive tree located in Abrantesin the center of Portugal. According to a study conducted by the University of Trás-Montes and Alto Douro (Utad), Mouchão It would be the tree that would have this record with an age that would be around 3,350 years. Spain also has ancient olive trees and among all of them stands out The Arión Fargaa tree that we can find in the province of Tarragona. The estimated age of this olive tree is more than 1,700 years. This implies that this millenary tree would have been planted at the time of Emperor Constantine I. Olives are not the only millenary tree species in our environment. Cedros, Secuoyas and even Dragos Canarios can also reach ages that would pale the biblical matusalem. The olive trees are trees with a long life expectancy but do not usually fill the lists of the longest trees on the planet. The two longest -known non -cloned trees are two pines called Prometheus and Matusalemto which ages are estimated above 4,000 years. Both belong (or belonged in the case of Prometheus) to the species Pinus Longaevathe “long -lived pine” so it is not completely surprising this fact. When Prometheus was cut, the botanists who analyzed him told more than 4,800 rings, so he was estimated at an age of about 4,900 years. Estimates indicate that Matusalem has also surpassed for decades The 4800 -year -old brand. If we include clonal organisms we can find older trees. For example, the Pando forestconsidered the largest living organism on the planet, composed of thousands of cuttings of the same clonic tree, could have close to 80,000 years old According to some estimates.
