Bilston Tree

The Bilston Tree or Bilston's Tree is a very large river red gum (Eucalyptus camaldulensis) growing near Brimboal in far western Victoria. The tree was saved from being felled in June 1961 for railway sleepers by local community action led by Bill Flentje, the District Forester at Casterton.

Negotiations between the Forests Commission Victoria (FCV) with the landowners, Mr Tomas Henry Bilston and his brother Mr John Wheeler Bilston, as well as Mr Lance Thyear from Pyramid Sawmills, led to the purchase the tree on 6 March 1962 for 70 pounds as compensation for the loss of revenue. The Bilston brothers donated a small patch of land (1 acre, 1 rood, 26 perches) plus a right of carriageway. The land was subsequently declared reserved forest on 28 May 1964 by the FCV.

In 1961, the tree was thought be about 400 years old and had a circumference estimated between 27 and 29 feet (measured at shoulder height - 5 foot). The total height was 135 feet.

The Bilston Tree is often claimed to be the world's largest river red gum but it is not. However, the unique thing about the Bilston Tree is its clear unbranched trunk, with very little taper, up some 40 feet. Estimates in 1971 suggested that 9,100 super feet (HLV) or 21.5 m3 of timber could be sawn from the tree, which is enough for over 300 railway sleepers. This probably makes the Bilston Tree the largest “merchantable” river red gum.

The tree was remeasured by a trained forester in June 2024 and had a circumference of 812 cm (at 1.3 m above the ground) and a height of 32.4 m. Reliable measurements are hard to obtain, but over the 53 year period from 1971 to 2024, the Bilston Tree grew a total of 86 cm in girth. This equates to an annual increment of 1.62 cm/year (or 0.51 cm/year in diameter).

The crown is thinning and showing signs of senescence while there is some epicormic growth from the lower trunk. Unlike many other old river red gums, there is no major swelling at the base or large burls. Some large branches broke from the tree in 1973 and again in 2013. The more recent one has been carved by local artists.

The Bilston Tree is recorded in both the National Trust and Heritage Victoria registers.
