Europe’s oldest trees?

At an age of anywhere between 2,000 and 5,000 years old, the Fortingall Yew in Perthshire, Scotland was believed to be the oldest tree in Europe (It is likely to be nearer 2,000 years old rather than 5,000. The age of yews can’t be measured by counting tree rings). It would seem that it has lost this record: scientists have found a cluster of spruces in western Sweden which, at an age of up to 8,000 years, may even be the world's oldest living trees.

The Norway spruces were found in a mountain range that separates Norway and Sweden. Carbon dating of the trees carried out at a laboratory in Miami showed the oldest of them first set root about 8,000 years ago, making it the world's oldest known living tree, Two other spruces, also found in the course of climate change studies in the Swedish county of Dalarna, were shown to be 4,800 and 5,500 years old.

"These were the first woods that grew after the Ice Age," said Lars Hedlund, responsible for environmental surveys in the county of Dalarna, Sweden "That means that when you speak of climate change today, you can in these (trees) see pretty much every single climate change that has occurred."

California's "Methuselah" tree, a Great Basin bristlecone pine, is often cited as the world's oldest living tree with a recorded age of between 4,500 and 5,000 years.
