Return of strip-field farming creates haven for rare species in south Wales

National Trust trial of 13th century method used until 1940s transforms stretch of Gower peninsula coast

A pioneering farming project using field management techniques dating back to the 13th century has transformed a stretch of coast into a haven for endangered animals, birds, insects and wildflowers.

The experimental return to "strip-field farming" close to the spectacular Rhossili Bay on the Gower peninsula in south Wales is being credited with a threefold increase in the number of species of wildflowers and the appearance of rare birds such as the hen harrier and grasshopper warbler.
