Centurion (tree)

The Centurion is the world's tallest known individual Eucalyptus regnans tree and E. regnans is the second-tallest tree species in the world after the coast redwood. The tree is located in southern Tasmania, Australia and was measured by climber-deployed tapeline at 99.6 metres (327 ft) tall in 2008.[1][2] Two more recent measurements indicated that the tree was growing, albeit very slowly. In January 2014 the tree was climbed and the tape drop indicated the tree had grown to 99.82m. However, a further tape drop done in 2016 obtained the slightly lower height of 99.67m [3] Centurion was re-measured again in December 2018 and was found to have possibly reached 100.5 meters in height. [4] However, this latest measurement was done with a laser and needs confirmation via a tape drop. It was discovered in August 2008 by employees of Forestry Tasmania while analysing the data collected by LiDAR system used in mapping and assessment of state forest resources.[5]

The diameter of Centurion is 4.05 metres, its girth exceeds 12 metres, and its volume has been estimated at 268 cubic metres. The name "Centurion" was saved for the hundredth noble tree to be discovered by Forestry Tasmania and coincided with the height of the tree. Named after centurions (Roman officers), the root of the name contains centum, which in Latin means "one hundred". Centurion is alternately known as "the Bradman" as the height of the tree at 99.82 metres was close to the test run average of the legendary Australian cricketer Donald Bradman.[6]

The tree is in a small patch of very old forest surrounded by secondary forest and has survived logging and forest fires by lucky coincidence. Near Centurion grow two other giant trees: the 86.5 metre tall E. regnans named Triarius and 'The Prefect' which has an impressive girth of 19m.

The tallest known coast Douglas fir is now listed at 99.7 m tall and comes a close third. Centurion is also the tallest known angiosperm in the world.
