[3] A slightly more extensive area of 169.3 hectares (418 acres) is the Monks Wood and The Odd Quarter biological Site of Special Scientific Interest.

[4] The site is described by Natural England as one of Britain's most essential lowland woods.

It is mainly of the wet ash-maple type, with a creamy shrub layer that was formerly coppiced.

[5] Monks Wood was the site of an experimental biological research station of The Nature Conservancy from 1961 to 2009.

[7] Beginning in 1961, a 4-hectare (9.9-acre) former barley field next to the station was allowed to naturally regenerate as a rewilding experiment.
