West Blean and Thornden Woods is a 781-hectare (1,930-acre) biological Site of Special Scientific Interest north of Canterbury in Kent.

[1][2] It is part of the Blean Woods Nature Conservation Review site (a Grade I site),[3][4] and an area of 490 hectares (1,200 acres) is a nature reserve managed by the Kent Wildlife Trust.

[5] The woods form one of the largest areas of ancient woodland in the UK, with parts of it over 1,000 years old.

The reintroduction to the UK in 2022, the first time in 6000 years (apart from an unsuccessful project in Scotland in 2011[7]), is to consist of a herd of 3 females and 1 male.

Exmoor ponies, iron age pigs and English Longhorn cattle are also to be released into the woods.
