A Swedish university research team has discovered what it thinks could be the world’s oldest tree at about 9,550 years of age.

In an interview with TTJ, Professor Leif Kullman said the spruce was one of a number ancient trees discovered within the mountains of Dalarna province.

Mr Kullman, of Ulmea University, said the research team had carbon dated dead wood linked to the root system of the tree to come up with the age.

He said the tree had survived so long by continually renewing itself with new trunks, with the current trunk about 4.5m high.

More details will appear in the next issue of TTJ.
