The World’s Oldest Tree Lives in Sweden
I'd always thought that the Methuselah Tree in California was the oldest living tree. Apparently there's some disagreement, as Old Tjikko is a clonal tree, meaning the trunks come and go but the roots stay living underneath [1].So if you're counting non-clone trees, Methuselah is the oldest. If you're counting clonal trees, some Quaking Aspens are believed to be between 80,000 and 1,000,000 years old [2].[1] https://allthatsinteresting.com/old-tjikko[2] https://en.wikipedia.org/wiki/Pando_(tree)
