The area forms part of the distinctive Breckland landscape region, a gorse-covered sandy heath which offers poor agricultural opportunities. Arguably, its use as a military training area has safeguarded a substantial archaeological landscape. Like many other military or restricted access areas in the UK such as Bovington Camp, the buffer area around Porton Down, and MOD areas on Salisbury Plain, it is the home of a wealth of rare species of flora and fauna already lost in other parts of the country. Parts of the training area are designated Site of Special Scientific Interest (SSSI).
