The oldest known living organism in Sweden is Old Tjikko, a remarkable Norway spruce approximately 9,566 years old.
Old Tjikko: Sweden's Ancient Living Landmark
Nestled in the remote mountains of the Dalarna province, Old Tjikko stands as a testament to nature's incredible endurance. While the visible trunk of Old Tjikko is relatively young, the tree's root system has been continuously regenerating for nearly ten millennia, making it one of the world's oldest known individual clonal trees.
A Legacy of Longevity
Old Tjikko gained international recognition for its extraordinary age, surviving through thousands of years by repeatedly growing new trunks, branches, and roots from its ancient genetic material. This process, known as vegetative propagation or clonal growth, allows the organism to persist far longer than any single stem could.
Here are some key facts about Old Tjikko:
- Species: Norway spruce (Picea abies)
- Estimated Age: Approximately 9,566 years old
- Location: Fulufjället Mountain, Dalarna province, Sweden
- Nature: It is a clonal tree, meaning the current visible trunk is genetically identical to the original tree that sprouted shortly after the last ice age. The current trunk is relatively young, but the underlying root system has survived continuously for millennia.
To provide a quick overview of its remarkable characteristics:

Understanding Ancient Life Forms
The concept of "oldest" in biology can sometimes be nuanced. While Old Tjikko's visible trunk might only be a few hundred years old, its persistence as a living organism relies on its incredibly ancient root system. This contrasts with individual trees that grow from a single seed and eventually die, such as the famous Methuselah tree in California, which is a single, non-clonal organism. Old Tjikko's method of survival allows it to be categorized among the most ancient living things on Earth, continuously regenerating itself from the same genetic blueprint that emerged at the dawn of the post-glacial period.
