Turvey's Piece (grid reference SO882301) is a 1.02-hectare (2.5-acre) biological Site of Special Scientific Interest in Gloucestershire near Deerhurst, notified in 1993.

It consists of Oak, Ash and the understorey is Hawthorn, Blackthorn, Elder, Field Rose and Crab Apple.

Old ridge and furrow indications on the woodland floor mean that the previous use of the site was agricultural meadow.

Key is Green Hounds-tongue which is listed on Schedule 8 of the Wildlife and Countryside Act 1981 (as amended).

[1] A Natural England assessment report of August 2010 indicates that the Green Hounds-tongue remains present, but states that the woodland is becoming denser.
