This page contains specific information about pedunculate oak (Quercus robur) '1919', which can be found in the park of Groenendaal in Heemstede. The girth of the tree, measured at a height of 1 m, is 7.38 m (2009, Leo Goudzwaard). As this tree is a tree with multiple trunks, the girth can be larger than what would be expected of the tree of this age. Its height is not known. This tree was planted around the year 1785 ± 10, which makes it around 230 ± 10 years old (Leo Goudzwaard, Oct 1, 2011).
