Which tree has the longest lifespan
The tallest tree in the world
At a height of 132.58 meters, an Australian giant eucalyptus measured in the 19th century holds the historical record.
Both the eucalyptus trees of Australia and the North American sequoia trees of the species "Sequoia sempervirens" can reach heights of over 100 meters.
The current record holders are also in the Californian coastal region. Until 1995 it was the "Tall Tree" in Redwood National Park at 112 meters.
Then the top broke off and the National Geographic Society Tree from the same park moved up to number one.
However, recent measurements in the park have shown that the coastal redwood "Hyperion" is the record holder with a height of 115.5 meters.
The oldest tree in the world
For a long time, scientists believed that the oldest trees in the world can also be found in California, in the White Mountains: the "Bristlecone Pines" or awning pines (Pinus aristata).
Their wood shows around 100 annual rings per centimeter. The oldest of them is called "Methuselah" and is over 4,700 years old.
In 2012, a tree was discovered in the same region and was dated to be 5062 years old. However, for fear of too many visitors, the exact location remains a secret.
The Tamrit cypresses in the Algerian Tassili Mountains are said to be 4,000 to 5,000 years old. Exact evidence is missing here, as is the case with a Japanese crescent fir on the island of Yakushima, the age of which is estimated to be around 7,000 years.
In 2008, however, Swedish researchers found a small spruce on Mount Fulu in the center of the country, dated to an age of 9,550 years.
The mightiest tree in the world
84 meters high and 31 meters in circumference - these are the dimensions of the approximately 2500 year old "General Sherman Tree". With a volume of around 1500 cubic meters, it is the most powerful tree in the world. It belongs to the genus of "Giant Sequoias" (Sequoiadendron giganteum), also called "Sierra Redwood".
The tree with the thickest trunk
It is neither the oldest nor the tallest tree in the world: the "Ahuehuete tree" in Santa Maria de Tule in the state of Oaxaca (Mexico), called "El Gigante".
But 58 meters of tribal circumference make him the front runner in this discipline. It is a Mexican bald cypress (Taxodium macronatum).
The tree with the oldest root system
The root network of the so-called "Huon Pine" in Tasmania is 10,500 years old - this is what scientists have discovered. New, genetically identical pine trees keep sprouting from the ancient roots.
The plant clones itself again and again. The oldest pine among them is about 2000 years old. Many very old plants use this trick.
In 2009, California scientists found a bush that has cloned itself for 13,000 years. So it still comes from the last ice age.
In the meantime, the bush named "Jurupa oak" has got used to the scorching heat of California and has adapted accordingly. He had enough time for that.
