There is one pedunculate oak (Quercus robur) behind the farm in Manthorpe in Manthorpe (county of Lincolnshire).
This tree is called "The Bowthorpe Oak". This oak at Bowthorpe Farm near Manthorpe village is the biggest girthed pedunculate oak in the UK. Only two sessile oaks have a marginally larger girth but their trunks are more ruined by time. About the age of the Bowthorpe oak there are different opinions. There has been done some research of the tree rings in the seventies, but while the oak is totally hollow this can be done only for the outer shell of wood (information Jeroen Pater - "Monumentale Bomen in Europa" , 2006). The growth of these outer rings has been extrapolated and the oak was estimated about 550 years old, so now nearing 600 years. An old source, a notition by a mr. Howell at the back side of a gravure of the tree of 1804, writes the tree was hollow and had a girth of 37 ft (11.3 m). The slow growth of the girth since then made several writers think the tree could be a 1000 years old. It is not possible to be sure ot the age, but a margin of 600 - 1000 years seems to be rather safe.[Top of page]

The girth of the tree is 13.16 m measured at a height of 1.30 m (Apr 6, 2006, Jeroen Pater). Its height is around 15.00 m (Apr 6, 2006, measurement method unknown, Jeroen Pater). This tree was planted around the year 1200 ± 200, which makes it around 813 ± 200 years old (Jeroen Philippona, Nov 8, 2012).
