As Open Country returns for a new series, Helen Mark ventures to The Isle of Sheppey where she becomes immersed both in the marsh swathed landscape of Elmley Nature Reserve and the infectious enthusiasm of the man who oversaw its creation.

Elmley is the only National Nature Reserve in the UK to be managed by a farming family and this unique status is down to the forward thinking of farmer Philip Merricks. Bumping along the ridge of the reserve's sea wall in his trusty 4x4, Philip introduces Helen to this historic Kent landscape, accompanied by the flight of lapwing and wigeon.

It's an area that is believed to have inspired Charles Dickens in the writing of 'Great Expectations' but as Helen discovers, it has also inspired an even bigger story of ground breaking conservation.

During the 1980's, farmers were paid compensation for turning land over to wildlife but Philip felt that this was unproductive for both farmers and wildlife and so wrote - what he calls - a fairly strong letter to the House of Commons Select Committee that had been tasked with finding a solution to what was becoming a rural battle ground. Remarkably, Philip's letter found its way into Parliament and his ideas were held up as a potential way forward.

Thirty years on Philip's enthusiasm and dedication to this one of a kind nature reserve is as strong as it ever and now - with the support and care of long standing farm manger Steve Gorden - Philip's daughter Georgina and son-in-law Gareth are moving forward with sharing this special place with visitors and encouraging that passion for farming and conservation that Philip began decades ago.
