Beddomeia hallae is a tiny (3-4 mm) freshwater snail occurring in tributaries of Buttons Rivulet on South Preston Rd, Nietta and headwater streams of the Castra Rivulet (including Deep Gully Creek), in central northern Tasmania. The species has a relatively narrow range, known only from a small number of streams, across an area of 20 square km. The principal threats to B. hallae are agricultural and forestry practices which result in habitat modification or degradation. B. hallae may also be vulnerable to competition with the exotic snail Potamopyrgus antipodarum, a species of hydrobiid introduced from New Zealand. The principal management objectives for B. hallae include preventing the loss or degradation of habitat supporting known populations, identification of new subpopulations, increasing public awareness of the species, and improving the species' reservation status.
