Leif Kullman, botanist at the Umea University based in Sweden has recently dated a red spruce of 8.000 years.
"Our results have shown the complete opposite, that the spruce is one of the oldest known trees in the mountain range," says Leif Kullman, Professor of Physical Geography at Umeå University.

The visible portion of the 13-foot-tall (4-meter-tall) "Christmas tree" isn't ancient, but its root system has been growing for 9,550 years, according to a team led by Leif Kullman, professor at Umeå University's department of ecology and environmental science in Sweden.
Discovered in 2004, the lone Norway spruce-of the species traditionally used to decorate European homes during Christmas-represents the planet's longest-lived identified plant, Kullman said. The researchers found the shrubby mountain survivor at an altitude of 2,985 feet (910 meters) in Dalarna Province. The tree's incredible longevity is largely due to its ability to clone itself, Kullman said. The spruce's stems or trunks have a lifespan of around 600 years, "but as soon as a stem dies, a new one emerges from the same root stock," Kullman explained.
A 9,500-year-old Norwegian Spruce was discovered in Sweden by Leif Kullman, professor of Physical Geography at Umeå University.
Carbon-14 dating determined the conifer, named "Old Tjikko" after Kullman's Siberian husky in 2004, took root at the end of the last Ice Age. It is located at an altitude of 2,985 feet on Fulufjället Mountain in Dalarna, in central Sweden. "During the ice age, sea level was 120 meters lower than today and much of what is now the North Sea was at that time forest," Professor Kullman said. Winds and low temperatures made Old Tjikko more like "a bonsai tree … big trees cannot get as old as this. The trunk of the tree, which is only 13 feet tall, is estimated to be a few hundred years old, but its root system has been growing for more than 9,550 years. The lone spruce is the planet's longest living identified plant, its incredible longevity due largely to its ability to clone itself, a process called vegetative cloning. "As soon as a stem dies, a new one emerges from the same root stock," Kullman explained.

Dr. Leif Kullman, a professor of physical geography at Sweden's Umeå University, explained how the tree clones itself through a process known as vegetative propagation: "...as soon as a stem dies, a new one emerges from the same root stock.
"Deglaciation seems to have occurred much earlier than generally thought," said Professor Kullman, "Perhaps the ice sheet during the Ice Age was much thinner than previously believed." Until the discover of "Old Tjikko", spruces were thought to have been a recent migration to the mountain. "Prior to our studies the general conception was that spruce migrated to this area about 2,000 years ago, so now you will have to rewrite the textbooks," said Professor Kullman. He also believes it is possible that Mesolithic humans introduced the spruce to the region as they wandered northward following receding ice sheets.
