There's even more info at this NatGeo page: http://news.nationalgeographic.com/news/2008/04/080414-oldest-tree.html
Curiously, there is a discrepancy between the previous 2 links on the age: one says 8000 and the other says 9550 years. And a bit of clarification is needed, as can be explored here: http://en.wikipedia.org/wiki/Oldest_tree
The term "oldest tree" is somewhat misleading, since it is only the root systems that have been carbon dated to 9550 years, not the "tree" above ground which do not live nearly as long. In the sense of "tree" that most of us think of, the oldest tree remains the 5000 year-old bristlecone pine in Nevada, U.S. named Prometheus according to the Wikipedia entry linked above.


The truth is out there, but so is a lot of other nonsense!
