The oldest tree in the world - Spruce is found in Swedish province Dalarna on the Fulu mountain. Tree is 9550 years old. Lot of years this tree was regarded as youngish. However new research has shown, that it not so, it's young trunk of ancient tree.
It is known, that Spruce growing in the Swedish mountains can survive in heavy conditions thanks to ability to grow up from root system the second trunk instead of the died.
Though the last of 10 thousand years the climate here was adverse, these trees have remained. And as last 100 years the average temperature of air in area Fulu has risen on one degree °C, ancient Spruce have begun to grow up actively. So, the young trunk of that 9550-year-old record-holder has started to last upwards, apparently, somewhere in 1940.
The previous oldest trees - pines in the North America - were dated 4-5 thousand years.
