A former dredging dump beside the Manchester Ship Canal in Warrington, England, has been transformed into Britain's most important breeding site for the black-necked grebe, now hosting 64% of the country's breeding population. Woolston Eyes (a nature reserve in Cheshire, northwest England) was restored from 2021 onwards by the RSPB and a local conservation group, with new freshwater pools and nesting islands created to attract the rare, ornately coloured waterbird. In 2025, 35 breeding pairs were recorded at the site, up from just four pairs in 2023, demonstrating how quickly targeted habitat restoration can drive wildlife recovery.
