Gilbert White, born on the 18th July 1720, is one of Britain's most influential natural scientists. He is often described as the Father of Ecology and revolutionised the way people observed and interacted with Nature. His main work 'The Natural History of Selborne' which was published in 1789 and is a series of letters to fellow naturalists has never been out of print and is thought to be the fourth most published book in the English Language. 'Open Country' steps back in time as we take a tour of Gilbert White’s garden and the surrounding landscape of Selborne 300 years after this pioneering naturalist and gardener was born, to explore the landscape and wildlife which so inspired him and which remarkably has changed relatively little since then.
