The Eastern Black Rail is a federally Endangered and extremely secretive marsh bird, found primarily along the mid-Atlantic and Southeast coast of the United States. Habitat loss from development and sea-level rise inundation has reduced populations by 90% since the 1990s. Without intervention, the remaining east coast population is projected to be extirpated before 2070. Black Rails’ breeding success is incredibly vulnerable to minute changes in water level, and in coastal regions experiencing dramatic changes in storm regimes and steadily rising seas, their future depends on precise water-level management within the critical sites that remain. South Carolina’s ACE Basin is a one such landscape, uniquely comprised of historically dike-impounded wetlands, which today provides a stronghold for some 30 breeding pairs. A grassroots partnership among private landowners, non-profit conservation groups, and state and federal agencies is working urgently to understand the rails’ precise and cryptic needs, and to develop the techniques—and support—required to create those conditions on the ground. The Cornell Lab’s Center for Conservation Media has produced “Weathering Tides” (13 minutes), a short film highlighting the unlikely partnerships and pioneering techniques of this dedicated coalition. The film will be used by agency and non-profit partners in South Carolina and across the Atlantic Coast to build the support and participation necessary to scale effective management efforts beyond the ACE Basin, and to recover Eastern Black Rail populations.
