There is one horse-chestnut (Aesculus hippocastanum)
behind the Bourne Rivulet river in Hurstbourne Priors (community of Hampshire)
This is the National Champion Horse Chestnut for girth and one of the tallest horsechestnuts of the UK. According to Alan Mitchell, the famous, late dendrologist, it is the finest all round in the country.

Girth growth rate
The girth was measured more than once:
|Year||Girth@1.5 m||Measurement||Girth growth rate|
|1955||6.10 m||Alan Mitchell||-|
|1995||6.70 m||Alan Mitchell||2 cm/year|
|2005||7.03 m||TheTreeRegisterOwenJohnson||3 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:
|2005||~35.00 m ||TheTreeRegisterOwenJohnson||Clinometer or tangent style (laser) hypsometer (e.g. Forestor Vertex)|
|2013-07-16||33.80 m||Jeroen Philippona||Laser with Sine method (e.g. Nikon Forestry 550 laser rangefinder)|
Each measurement can be done with varying accuracy.This tree was planted around the year 1700 ± 50, which makes it around 314 ± 50 years old (Jeroen Philippona
, Aug 3, 2013).
