High in the rugged highlands of northern Greece, a remarkable discovery has rooted itself in both history and science.
Researchers have identified what might be Europe’s oldest living tree—a resilient Bosnian pine (Pinus heldreichii) named Adonis, estimated to be at least 1,075 years old.
This ancient giant, standing firm since 941 AD, offers more than just a breathtaking reminder of nature’s endurance.
It holds the potential to unveil a millennium of climate history, giving scientists an unprecedented window into how the environment has evolved over centuries.
“To age the tree, we needed to take a core of wood, from the outside to the center.
The core is 1 meter (3.2 feet) long and has 1,075 annual rings,” explained Paul Krusic, leader of the research team from Stockholm University.
Adonis is not alone in its longevity. Nearby, a community of similarly ancient trees thrives, some also over a millennium old.
Together, they form a living archive of environmental change, untouched by human interference for centuries—a rare phenomenon in a region steeped in civilization for over 3,000 years.
Trees as Witnesses to Civilization
When Adonis first sprouted in 941 AD, the Byzantine Empire was flourishing.
Over the next thousand years, it witnessed the rise and fall of empires, from the Ottomans to modern Greece.
By the time Adonis celebrated its 1,000th birthday, the world was grappling with World War II, and Greece was under Nazi occupation.
The survival of this tree in such an inhospitable environment, surrounded by human activity, is nothing short of extraordinary.
Krusic reflects, “I am impressed, in the context of western civilization, all the human history that has surrounded this tree; all the empires, the Byzantine, the Ottoman, all the people living in this region. So many things could have led to its demise.”
Challenging Assumptions About Longevity
When discussing ancient trees, names like Methuselah and Old Tjikko often dominate the narrative.
Methuselah, a bristlecone pine in California, is estimated to be around 4,600 years old, predating the construction of the pyramids.
Meanwhile, Old Tjikko, a clonal tree in Sweden, boasts a root system that is an astonishing 9,550 years old, though its visible stems regenerate every 600 years or so.
But here’s the twist: Adonis, while younger by comparison, offers something uniquely valuable. Unlike clonal organisms, which regenerate parts of themselves, Adonis has survived as a single, continuous organism.
Its rings provide an unbroken timeline, a year-by-year record of climate and environmental conditions stretching back over a millennium.
This sets Adonis apart.
It’s not just a biological marvel; it’s a historian, preserving secrets about droughts, temperature shifts, and ecological changes that could reshape our understanding of Europe’s past.
The Science Behind the Discovery
The research team employed dendrochronology, the science of dating tree rings, to determine Adonis’ age.
Each ring represents a year of growth, with variations in ring width reflecting environmental conditions such as rainfall, temperature, and soil quality.
Krusic and his team carefully extracted a core sample from Adonis without harming the tree.
This sample revealed 1,075 rings, and because the core wasn’t taken from the base, the tree’s actual age might be even greater.
“In our research, we try to build long chronologies to construct climate histories, so finding living trees of old age is one of our motivations,” Krusic said.
The discovery of Adonis wasn’t accidental. The research expedition targeted the forest near Greece’s Pindos Mountains, a region long suspected to harbor ancient trees.
Their findings exceeded expectations, with multiple trees in the area surpassing the 1,000-year mark.
A Climate Archive
Adonis is more than just a biological curiosity; it’s a time capsule. By analyzing its rings, scientists can reconstruct past climates with remarkable precision.
Each ring contains chemical markers that correspond to specific weather patterns, such as prolonged droughts or unusually wet years.
This data is invaluable. As the world grapples with modern climate change, understanding historical patterns can help scientists predict future trends and develop strategies for mitigation.
The forest’s untouched nature enhances its scientific value.
Unlike other regions, where human activity has often distorted environmental records, this pristine ecosystem provides a rare, unaltered view of natural history.
A Legacy of Survival
The survival of Adonis and its neighboring ancient trees is a testament to nature’s resilience.
Despite inhabiting a land “civilized for over 3,000 years,” these trees have endured wars, empires, and the relentless march of time.
Their longevity challenges humanity to reconsider its relationship with the natural world.
What lessons can we learn from these silent witnesses to history? How can their stories inspire us to preserve the fragile ecosystems we rely on?
Trees Across the Globe
Adonis is part of a larger narrative about the world’s oldest trees.
From the towering redwoods of California to the ancient cedars of Lebanon, these arboreal giants remind us of the planet’s enduring beauty and fragility.
Each tree tells a unique story. Methuselah speaks of ancient deserts; Old Tjikko whispers secrets of post-Ice Age Europe.
Adonis, meanwhile, stands as a sentinel of Greece’s rich history and evolving climate.
What’s Next for Adonis?
The researchers plan to publish their findings in the coming months, shedding light on Adonis’ role in understanding climate change.
Their work could offer new insights into how forests respond to long-term environmental shifts, providing a roadmap for conservation efforts.
“It is quite remarkable that this large, complex, and impressive organism has survived so long,” Krusic said.
As the world races to combat climate change, trees like Adonis remind us of nature’s resilience—and its vulnerability.
They also highlight the importance of preserving ancient ecosystems, not just for their beauty but for the invaluable knowledge they hold.
A Living Legacy
Adonis, now over 1,075 years old, is more than just a tree. It’s a symbol of endurance, a keeper of secrets, and a bridge between the past and future.
As scientists delve into its rings, they unlock stories of a world long gone, offering lessons for the challenges that lie ahead.
