Wie alt ist älteste baum erde
Eine Mikroskopuntersuchung brachte es ans Licht - die älteste Baumart der Welt ist die Grannenkiefer. Die eher unbedeutend aussehenden Nadelbäume, die erst 1956 in den kalifornischen "White Montains" entdeckt wurden, können mehrere tausend Jahre alt werden. Das liegt vor allem daran, dass sie als Hochgebirgsbewohner robust und in ihrer Lebensführung recht anspruchslos sind.
Rekordverdächtig: 4600 Jahre!
Die ältesten Exemplare - 17 an der Zahl - sind nachweislich weit über 4000 Jahre alt und dabei kaum mehr als zwölf Meter hoch. Der Veteran unter ihnen zählt sogar 4.600 Lenze! Eine Zahl, die unglaublich klingt, aber wahr ist. Eine Analyse der Jahresringe hat dieses Ergebnis bestätigt. Es ist nicht ausgeschlossen, dass sogar noch ältere Bäume existieren. Dafür gibt es aber keine wissenschaftlichen Beweise.

Wie alt ist der älteste Baum der Erde?
lach* wüßte ja mal gern, wo die diese auf's Jahr genaue Angabe herhaben
Eigentlich da ist ein aelterer baum, eine kiefer arte ueber 5000 jahre alt und hoeher den 30 stockwerke. Steht 1000 miles unterhalb des arktischen circles. On a wild Tasmanian mountain there is a magnificent, recently discovered stand of Huon pine trees that has been called the world's 'oldest known living organism'. Newspaper reports have claimed that what looks like hundreds of trees densely covering one hectare , is all part of the one tree, since all these 'trees' appear to have identical DNA. Over the years, it is believed, 'snow has forced its branches to the ground, where they have taken root'. It is hard to see how a tree could be older than the time since the biblical Flood, so if its published age of 'more than 10,500 years old' were correct, then this would present a serious challenge to Old Testament chronology. In fact, some media reports claim the tree 'could be 30,000 or 40,000 years old'.
The media reported that scientists had definitly found the world's 'oldest living organism' in these Tasmanian Huon pines. A scientist working on the project said, 'we have made no such claim'.
So have these dates been obtained from drill-core sampling of the growth rings in the main trunk? Not surprisingly, the answer is 'no'. The source of the reported 'age' may be a 'guesstimate' based on core sampling a lake below the mountain which contains Huon pine pollen. This is clearly based on far more assumptions and uncertainties than tree-ring dating. Even the apparent absence of DNA differences is not 100 per cent certain, it seems, though probable.
It appears that traditional tree-ring dating on any timber found growing at the site so far gives an age of no more than 4,000 years. This is well within the ages of the oldest living bristlecone pines, which have around 4,600 tree-rings and are still the world's oldest living organisms. One of the scientists working on the project has issued a statement on electronic mail saying that they had only said it was plausible that these trees might turn out to be part of a much older tree that was now underground, but that this was definitely not a foregone conclusion. He said the media 'decided to run with the story that scientists working in Tasmania have definitely found the oldest living organism in the world. We have made no such claim'.
If there was a global Flood around 5,000 years ago, no living thing should be older than that. There are still some uncertainties with tree-ring dating, which is by no means absolute. Nevertheless, it is worth noting that the maximum tree-ring ages for living trees fall just within this range. Apart from the biblical Flood, there seems no reason why, if certain trees are capable of living for 4,000 years, some should not have lasted much longer.
