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 around 30.00 m (2005, measurement method unknown, Wilma Verburg). This tree was planted around the year 1935 ± 10, which makes it around 79 ± 10 years old (Wilma Verburg, Oct 1, 2011).
