El Árbol del Tule (
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),[2] an increase from a measurement of 11.42 m (37.5 ft) m in 1982.[3] 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).[2] This is slightly wider than the next most stout tree known, a giant sequoia with a 8.90 m (29.2 ft) diameter.[4]
The height is difficult to measure due to the very broad crown; the 2005 measurement, made by laser, is 35.4 m (116 ft),[2] shorter than previous measurements of 41–43 m (135–141 ft).[3]
It is so large that it was originally thought to be multiple trees, but DNA tests have proven that it is only one tree.[5][6] This does not rule out another hypothesis, which states that it comprises multiple trunks from a single individual.[7]
The age is unknown, with estimates ranging between 1,200 and 3,000 years, and even one claim of 6,000 years;
The tree is occasionally
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 travelling daily on a nearby highway.[10]
