Just like Treebeard the Ent claims to be the oldest creature in Middle Earth, trees are amongst the earliest living beings on real Earth too. The earliest tree depends upon what you count as a “tree” but varies from 5,000 to 80,000 years. Now thats a very long time!
Trees have actually been around for such a long time due to the fact that a long life means that there is more chance to replicate. For that reason a longer life has been evolutionarily chosen for, and trees have distinct capabilities such as having the ability to change organs, part of the tree being able to endure even if the whole is damaged, and their range of defense compounds.
There are 2 types of trees that we need to think about when talking about tree age: private trees and similar clonal nests. Clonal nests differ from private trees in that each tree in a nest is genetically similar and linked by means of a root system, so you can consider them as one organism although there might be many trees. Clonal colonies may be old as an entire, but no single tree is particularly old.

The earliest single tree on the planet
The oldest tree worldwide is this species, a bristlecone pine. Image credits: daveynin.
Because 2013, Methuselah has actually been surpassed as the worlds earliest tree by the discovery of another P. longaeva also situated in the White Mountains with an estimated age of over 5,060 years. When this tree first began growing from seedlings, the wheel was barely created in Mesopotamia.
Till recently, the oldest tree on the planet was extensively concerned to be a 4,850-year-old Great Basin bristlecone pine (Pinus longaeva) called Methuselah. Called after the biblical figure stated to have lived for 969 years, Methuselah has actually stood in the White Mountains for more than four and a half centuries. To put that into perspective, when Methuselah first settled, the ancient Egyptians were simply starting to build the Great Pyramid of Giza.
What makes the bristlecone pines, consisting of Methuselah, able to make it through for such an extraordinary quantity of time? The essential lies in the trees amazing ability to adapt to its extreme environment.
Single trees can be measured straight for how old they are. Usually, researchers count tree rings or approximate their age from the trees size and growth rate. The trunk reveals how old the entire tree is (this may sound apparent, however we will see later on that it isnt).
In addition to these physical adaptations, bristlecone pines have actually likewise established a distinct way of growing. Instead of growing constantly, the tree includes brand-new cells to the suggestions of its branches, enabling it to endure even when conditions are incredibly dry.
Another essential adjustment of the bristlecone pines is the trees ability to endure on exceptionally poor soil. The rocky, nutrient-poor soils discovered in the White Mountains would be unwelcoming to most other trees. But the bristlecone pines have actually developed a deep root system that allows them to draw out water and nutrients from the soil.
The exact place of both trees is a carefully safeguarded trick to safeguard the tree from vandalism and damage. Prometheus, which would be the third oldest was cut down in 1964 by a researcher who wasnt familiar with how old it was.
One of the most crucial adjustments of the bristlecone pines is their twisted, knotted appearance. The trees twisted shape helps to safeguard it from the strong winds that sweep through the White Mountains. The trees branches are also reasonably little and near the trunk, lowering the amount of surface location exposed to the sun, which helps to save water.
These pines arent the only trees that can live a long time; cypress, olive trees, and yew tree have actually likewise been found to be over 3,000 years of ages. There could be other truly old trees, however they havent been determined.
The Bristlecone pines have likewise been understood to stop growing for decades, which can assist them to survive during droughts, and when resources are limited.
The earliest clonal nest
Old Tjikko, a Norway Spruce (Picea abies), in Norway is frequently called the worlds oldest tree. However, the distinction requires to be made that it is really a clonal tree, and if you compare it to Pando then its still an infant colony. The tree lives to be about 100 however Old Tjikkos root system is 9,550 years of ages. It is likely the only living trunk left from a former nest that began growing in the last Ice Age. 4 generations of remains were found at the website, all genetically similar.

Here are a few examples of very old clonal tree nests. A colony of trembling aspen trees (Populus tremuloides) in the Fishlake National Forest Utah called Pando is thought to be one of the earliest and largest organisms in the world. It covers 106 acres (43 hectares), consists of around 47,000 individual trees that all share the very same single root system, and it is at least 80,000 years old.
The trees themselves might not actually be so old, the root system and the whole organism might be much older than any individual tree. If you aged a single tree then you would think that the tree isnt so old, however if you aged the root system, such as with radiocarbon dating, it can be much, much older.
Clonal colonies are composed of genetically similar trees that are linked by a root system. Though the trees themselves may not in fact be so old, the root system and the entire organism might be much older than any specific tree. If you aged a single tree then you would believe that the tree isnt so old, but if you aged the root system, such as with radiocarbon dating, it can be much, much older.
All in all, these trees are very old. Contemporary humans were simply spreading to Asia from Africa when Pando began growing. The earliest private tree began growing at about the exact same time as Stonehenge was very first built, Troy was founded, and the very first pharaohs ruled. These trees still stand as a residue from a time long past.
The oldest tree depends on what you count as a “tree” but ranges from 5,000 to 80,000 years. There are two types of trees that we need to think about when going over tree age: private trees and similar clonal nests. Clonal colonies might be old as an entire, however no single tree is particularly old.
