Councillor Anthony Froud, chairman of the Nonsuch Park joint management committee, said: “This is an incredible achievement and a reflection of the dedication of our volunteers and staff.
“Local volunteers, the Nonsuch Voles and the Council’s Countryside, Property and Estates, and operational teams work year-round to protect and enhance this unique heritage landscape for the benefit of wildlife, visitors and future generations.
“These gold awards celebrate their hard work and the deep pride our community takes in Nonsuch Park.”
The result comes after work to restore heritage features of the garden, such as the greenhouse and the presence of several champion trees, a designation given to selected trees that are special because of their height, size, or significance.
