Justification: Assessed as Vulnerable on the basis that it has an estimated area of occupancy (AOO) of less than 2,000 km², where it is restricted 10 separate river basins (treated as separate locations on the basis of known threats from introduced species), and is suffering from an ongoing range reduction (due to the impact of the invasive species Rutilus rubilio), a decline in habitat quality, mainly due to channelisation and piping of water courses, and a decline in extent of occurrence (EOO) and AOO. A decline in the number of mature individuals is assumed due to the reduction in AOO. |
