Woolston Eyes Wetland Restoration Fuels Surge in Black-Necked Grebe Numbers

Woolston Eyes in Cheshire, a former dumping ground for dredgings from the Manchester Ship Canal, has been transformed into a mosaic of freshwater pools, reedbeds, willow scrub and rough grassland. The restoration, begun in 2021 and overseen by the Royal Society for the Protection of Birds (RSPB) together with the Woolston Eyes Conservation Group, created nesting islands and revived wetland areas on a dried-out settlement lagoon. The project also aimed to attract black-headed gulls, whose presence offers predator protection for the black-necked grebe.

The newly created habitat quickly proved valuable for the rare black-necked grebe. In 2023, four pairs bred on the site and successfully raised 15 young. By 2025, surveys recorded 35 breeding pairs, 29 of which nested on the restored wetland. This concentration represents 64 % of the average number of breeding pairs recorded annually across the United Kingdom, making Woolston Eyes the nation’s most important stronghold for the species.

“It is fantastic to see black-necked grebe numbers increasing at Woolston Eyes thanks to the hard work of staff, volunteers and partners to create prime habitat for this rare and attractive species,” — Gavin Thomas

Gavin Thomas, an RSPB ecologist, highlighted that the rapid increase demonstrates how targeted conservation can produce measurable results. He added that the success underscores the need to replicate similar wetland projects throughout the UK to support not only black-necked grebes but the broader community of wetland-dependent birds.

Woolston Eyes is designated a Site of Special Scientific Interest (SSSI) and supports other rare birds such as willow tit, pochard and grasshopper warbler. Because the site relies solely on rainfall, water can be moved between sections to create a rotation of drying, refreshing and reflooding—an essential management practice for grebes that abandon overly mature wetlands. The dramatic rise in grebe numbers illustrates the broader conservation principle that restoring and actively managing wetlands can drive recovery of vulnerable species, offering a model for future habitat projects across Britain.
