Hannah's Meadow Nature Reserve has some of the least improved and species rich upland hay meadows in upper Durham. The meadows were previously farmed by Hannah Hauxwell, who managed the meadows using traditional methods that avoided adding artificial fertilizers or reseeding. By doing so the species rich habitat hay meadow habitat that evolved over centuries was maintained. When Hannah retired in 1988 Durham Wildlife Trust purchased her farm and they now manage it as a nature reserve. An unmanned visitor centre at the site provides information about Hannah and her special meadows. Note facilities are located at Balderhead Reservoir car park.
