El Árbol del Tule (Spanish for The Tree of Tule), occasionally nicknamed the "Tree of Life", is located on the church grounds in the town center of Santa María del Tule in Mexico. Having the stoutest trunk of any tree in the world, was placed on a UNESCO list of World Heritage Sites, in 2001.
Originally was thought to be multiple trees, but DNA tests proved that it is only one tree. Though the age is unknown, estimates rang between 1,200 and 3,000 years, and there is even one claim of 6,000 years. The best scientific estimate based on growth rates is 1,433 to 1,600 years.
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.
