Nam pat district: In the heart of the lush forests of Ton Sak Yai National Park, Uttaradit Province, lies a tree that is not only a natural wonder, but also a center of loyalty and a monument to the great royal commitment to conservation: “Mahesak,” the world’s largest living teak tree.
According to Thai News Agency, “Mahesak” is a historical witness that has stood for over 1,500 years. This giant teak tree was first discovered in 1927 and is astonishing in its size: its trunk has a circumference of 10.22 meters and once stood as high as 38.50 meters. Although time and storms have taken away its crown, its strong trunk still represents greatness and sacredness, just like the meaning of the auspicious name bestowed upon it later.
A significant day in history, January 14, 1998, marks a pivotal moment in conservation efforts. On this day, Her Majesty Queen Sirikit, the Queen Mother, visited the large teak tree. With a heart devoted to nature and the environment, she delivered a royal speech that emphasized the importance of conservation: “Let’s help maintain and preserve the large teak trees so that they live as long as possible.” This message became the “Green Royal Aspiration,” inspiring ongoing forest conservation efforts. Consequently, a maintenance committee was established in 1998 to ensure the continuous monitoring and health of “Mahesak.”
On September 29, 2009, the history of the great teak tree was further enriched when Her Royal Highness Princess Maha Chakri Sirindhorn graciously named it “Mahesak,” meaning “great angel.” This name truly reflects the tree’s significance and sacredness to the forests and the land of Thailand.
Adjacent to “Mahesak” stands another significant tree, the “Sak Somdej,” planted by Her Majesty the Queen Mother during her 1998 visit. Today, the “Sak Somdej” thrives as a testament to the enduring legacy of the monarchy’s love for nature, forests, and the environment, reinforcing the “Green Royal Initiative” from past to future.
The “Mahesak” tree is celebrated as Thailand’s number one miraculous tree and a uniquely precious natural resource globally. It serves not just as a forest entity but as a symbol of royal grace and the profound connection between the monarchy and Thailand’s natural heritage-a conservation legacy that will endure forever.
