Rumex bidens (mud dock) is a distinctive aquatic to semi-aquatic species, known in Tasmania from about a dozen sites ranging from Low Head in the north to Pontville in the south, though many sites have not been seen in recent years. Available information suggests that subpopulations are very small in numbers and the area that they occupy placing the species at risk of losses from chance events. The risk of inadvertent losses is exacerbated as the species may not emerge when its habitat is dry, sometimes for many years. Threats to the species and its wetland habitat include changes to hydrological processes for irrigation and conversion for agriculture, stock browsing and trampling, and competition. The species would benefit from retention of buffering vegetation surrounding its waterway and wetland habitat, and known occurrences would benefit from stock management.
