There is one pedunculate oak (Quercus robur) Kvilleken in Norra Kvill (municipality of Vimmerby).
This tree is called "Kvilleken". The Kvilleken (Kvill's Oak), named after the closeby hamlet of Norra Kvill, is Europe's thickest oak. Like all old oak trees, the tree has a hollow trunk, so it is impossible to determine its age by simply counting tree rings.
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.

This tree is called "Kvilleken". The Kvilleken (Kvill's Oak), named after the closeby hamlet of Norra Kvill, is Europe's thickest oak. Like all old oak trees, the tree has a hollow trunk, so it is impossible to determine its age by simply counting tree rings.
A part of the trunk must have died off a long time ago and is currently attached to the rest of the trunk using cables, so the tree cannot collapse further. Although many trees claim to be over a thousand years old, a magical age like this is not so unlikely for this particular tree.
The girth of the tree is 14.75 m measured at a height of 1.30 m (Apr 9, 2006, Jeroen Pater). Its height is around 16.00 m (Jul 25, 2000, measurement method unknown, Jeroen Philippona). This tree was planted in 1500, which makes it exactly 513 years old (Tim B, Oct 1, 2011).
