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.
Its height is not known. This tree was planted around the year 1950 ± 10, which makes it around 65 ± 10 years old (Leo Goudzwaard, Oct 1, 2011).
Girth growth rateThe girth was measured more than once:
|Year||Girth@0.5 m||Girth@1 m||Measurement||Girth growth rate|
|2009||?||3.85 m||Leo Goudzwaard||-|
|2014||4.02 m||?||smal65||0.2 cm/year|
The tree is a specimen of the cultivar Ulmus glabra 'Exoniensis'.
