In this episode of This Old Tree, Doug introduces us to S'Ozzastru and the Ancient Olive Trees of Sardinia. Some trees are old — and then there's S’Ozzastru. Nestled near the village of Luras on the island of Sardinia, this ancient olive tree has stood for nearly 4,000 years. Also known as "The Great Patriarch" or "The Patriarch of Nature," the Bronze Age tree is a living witness to the rise and fall of civilizations. How has it endured for millennia? Who, across the centuries, has found shelter beneath its branches? And will the millennial olive trees of Sardinia continue to survive? Join us as we travel to the heart of the Mediterranean in search of secrets to one of the world’s oldest living trees.
