Old Tjikko - World's Oldest Tree
On Fulufjället is a clone of a fir tree that grew at the same point in 9550 years!
The spruce can reproduce and survive by shooting new suckers and it's like that this spruce has survived since it took root in Fulufjället just after the last ice age. During cold periods, the spruce grown more as a shrub and when the climate was more favorable, it looked like a tree.
It is Professor Leif Kullman at Umeå University, who examined the tree line on Fulufjället and with the investigation of age were determined wood residues are found under the tree with the so-called coal 14-method. That made it available for them to conclude that the same genetic individual has existed at this location for over 9000 years!
