There is one giant sequoia (Sequoiadendron giganteum)
in the woods of de Horstlanden in Enschede
Girth growth rate
The girth was measured more than once:
|Year||Girth@1.3 m||Measurement||Girth growth rate|
|2006||4.34 m||Frans van der Burg||-|
|2014||4.79 m||Maarten Windemuller||6 cm/year|
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.
The height was measured more than once:
|2006||~37 m ||Frans van der Burg||Measurement method unknown|
|2014-01-12||38.80 m||Maarten Windemuller, Han van Meegeren en Jeroen Philippona||Laser with Sine method (e.g. Nikon Forestry 550 laser rangefinder)|
Each measurement can be done with varying accuracy.
