Árbol del Tule
El Árbol del Tule (Spanish for The Tree of Tule) is a tree located in the church grounds in the town center of Santa María del Tule in the Mexican state of Oaxaca, approximately 9 km east of the city of Oaxaca on the road to Mitla. It is a Montezuma cypress (Taxodium mucronatum), or ahuehuete (meaning "old man of the water" in Nahuatl). It has the stoutest trunk of any tree in the world. In 2001 it was placed on a UNESCO tentative list of World Heritage Sites.
Dimensions and age
In 2005, its trunk had a circumference of 42.0 m (137.8 ft), equating to a diameter of 14.05 m (46.1 ft), a slight increase from a measurement of 11.42 m (37.5 ft) m in 1982. However, the trunk is heavily buttressed, giving a higher diameter reading than the true cross-sectional of the trunk represents; when this is taken into account, the diameter of the 'smoothed out' trunk is 9.38 m (30.8 ft). This is still slightly larger than the next most stout tree known, a Giant Sequoia with a 8.98 m (29.5 ft) diameter.
The height is difficult to measure due to the very broad crown; the 2005 measurement, made by laser, is 35.4 m (116 ft), shorter than previous measurements of 41–43 m (135–141 ft). According to the signboard by the tree (see gallery, below), it has a total volume of 816.829 m3 and a weight of 636.107 t (701.188 short tons); these figures are however not independently verified, and given the same signboard's claim of a girth of 58 m (190 ft), must be treated with suspicion.
It is so large that it was originally thought to be multiple trees, but DNA tests have proven that it is only one tree. This does not rule out another hypothesis, which states that it comprises multiple trunks from a single individual.
The age is unknown, with estimates ranging between 1,200 and 3,000 years, and even one claim of 6,000 years; the best scientific estimate based on growth rates is 1,433-1,600 years. Local Zapotec legend holds that it was planted about 1,400 years ago by Pechocha, a priest of Ehecatl, the Aztec wind god, in broad agreement with the scientific estimate; its location on a sacred site (later taken over by the Roman Catholic Church) would also support this.
The tree is occasionally nicknamed the "Tree of Life" from the images of animals that are reputedly visible in the tree's gnarled trunk. As part of an official project local schoolchildren give tourists a tour of the tree and point out shapes of creatures on the trunk, including jaguars and elephants.
In 1990 it was reported that the tree is slowly dying because its roots have been damaged by water shortages, pollution and traffic, with 8,000 cars traveling daily on a nearby highway.
