Next to the highest known eucalypt - Centurion in August 2008 there was discovered another tree giant - Triarius.

Triarius is enormous eucalypt - swamp gum (Eucalyptus regnans F.Muell.), 86.5 metres high. The tree was discovered in August 2008 by Forestry Tasmania employees Mayo Kajitani and David Mannes while analysing the data provided by airborne laser equipment LiDAR. The tree was discovered together with the nearby Centurion - the highest eucalypt in the world.

Named after the triarii - wealthy and influential fighters in Roman legions.

Contrary to Centurion the height of Triarius was comparatively easy to measure from the ground with laser equipment. Diameter of the trunk – impressive 3.90 m (2).

Discovered forest giants were located in non-protected state forest but immediately were included in the list of protected trees.

This is lucky coincidence that Centurion has survived. Wildfires in 1934 spared just a few older trees in this area and passed on west side. In 1950 there was logging nearby and at that time this giant tree would not be spared. In 1966 and 1967 the forest close nearby was deliberately burned for later regeneration, in 1967 this turned into furious, devastating fires. This time fire passed the tree on east side (1).

These fires were a reason why the forest around the giants was not oldgrowth and thus – not protected. It was not expected to find any tall trees in this area.
