Giant sequoia on the estate Rond Chêne

This page contains specific information about giant sequoia (Sequoiadendron giganteum) '284', which can be found on the estate Rond Chêne in Esneux.

This magnificent tree is the biggest tree of Belgium and the biggest giant sequoia of the Benelux countries (Belgium, Netherlands, and Luxembourg).

According to tree specialist Charlier, the owner of the neighbouring domain "Closerie du Rond Chêne", this tree was planted in 1891 by gardener Léon Crépin, which means that the girth of this tree has increased about 8 cm yearly on average.

The tree maintains its large girth near the bottom up until a quite large height, which makes it probable that this giant sequoia is the most voluminous tree in Belgium. I estimate the volume myself at about 96 m³. If correct, then this tree is by far the tree with the most voluminous trunk in the Benelux.

Girth growth rate

The girth was measured more than once:

The growth rate shown in the table shows the yearly average increase in girth since the last measurement. This value only gives an indication of the growth rate, since every measurement could be done at slightly different heights and during different periods of the year.

Each measurement can be done with varying accuracy.This tree was planted in 1891, which makes it exactly 123 years old (BELTREES, Oct 1, 2011).
