The High Court on May 28, 2026 declared that Natural England had breached its statutory duty to protect Catfield Fen from nitrate and phosphate runoff, a rare wetland that hosts about 2,500 species, including bitterns and swallowtail butterflies. Judge John Thorne said the regulator’s failure to act violated the 2009 Wildlife and Countryside Act.
This victory is the third in a 15‑year legal saga that began in 2016 when the Harrises won a public inquiry exposing excessive groundwater extraction by local water companies. In 2022, a separate judgment forced the Environment Agency to curb water abstraction near other Broads sites.
Since buying the 460‑acre farm in 1994, Tim and Geli Harris have converted arable land into pasture and maintained Eriskay ponies, hoping to reduce soil erosion and protect the fen’s fragile hydrology. Their conservation work has earned praise from ecologists but has drawn criticism from neighboring farmers who argue that groundwater restrictions hurt potato yields.
"We are not against farming," Geli Harris told a local radio station, "but we must farm responsibly so the wider ecosystem doesn't collapse." Natural England’s chief environmental officer, Sarah Patel, replied that the agency will review its monitoring protocols.
The court has set a deadline of July 1, 2026, for Natural England to design and install 200 metres of grass‑buffer strips along the fen’s drainage ditches and to publish a quarterly compliance report. The Harrises expect the regulator to increase staffing and resources for on‑site inspections.
The decision signals a turning point in environmental enforcement in the Broads, where overlapping authorities have historically diluted accountability. Local conservation groups say the ruling will set a precedent for other wetlands under threat from agricultural pollution.
Nationally, the case has sparked debate over the adequacy of statutory duties assigned to Natural England, with some lawmakers calling for a review of the agency’s powers and budget.
As the deadline approaches, the Harrises plan to monitor compliance from their own farm, hoping to see measurable reductions in nutrient levels and a rebound in butterfly populations.
