Aston Rowant National Nature Reserve is located on the north-west escarpment of the Chiltern Hills, in the Chilterns Area of Outstanding Natural Beauty.[1] It has an area of 159.1 hectares (393 acres),[2] and most of it is a 128.5 hectares (318 acres) biological Site of Special Scientific Interest.[3][4] It is listed as a Grade 1 site in A Nature Conservation Review.[5] The reserve is in several sections, mostly in the parish of Lewknor in Oxfordshire, with smaller sections in the parish of Stokenchurch in Buckinghamshire.
The reserve is home to plants and butterflies of chalk grassland. The flowers include at least seven species of orchid and the Chiltern gentian; the butterflies include the silver-spotted skipper and the Adonis blue.
As well as chalk grassland, the reserve contains woodland with beech, yew, and juniper. Overhead, reintroduced red kites are resident.
