Justification of Red List category
This enigmatic flightless rail is classified as Vulnerable because it has a small population, which is likely to be declining and undergoing fragmentation owing to the on-going loss of its specialised habitat. However, it is poorly known, and further surveys may reveal it to be more numerous and occur in a wider range of habitats than current information suggests.
2500-9999 mature individuals
