Conservation
Van Cutsem inherited his father's stud Northmore Farm in Exning near Newmarket, Suffolk, in 1976. He also owned a 4,000-acre estate in Norfolk, best known for its private wild game shoots. In 2001, the estate had thirty-five pairs of stone-curlews, a very rare bird. In addition he owned a hunting lodge and grouse moor on the North Yorkshire-Cumbria border. In the 1990s, he sold his father's farm in Exning and purchased the Hilborough estate in Norfolk, whence he transferred his horse-breeding operations. In 1994, he won a Country Landowners' Association award for his restoration of an old barn on the Hilborough estate; Charles, Prince of Wales presented the award. He was a founding member of the Countryside Movement, a conservationist non-profit organization. He was also a significant fundraiser for the Game & Wildlife Conservation Trust, a British charity highlighting game and wildlife management for the benefit of conservation. Moreover, he served as Chairman of the Countryside Business Trust. He was also elected to the Council of the National Trust.
