Justification of Red List category
While this species can now be found reliably in parts of the East Usambara plateau, Tanzania, virtually nothing is known about its recent status in northern Mozambique. Its low population density and the small area of suitable habitat indicate that its total population is extremely small. Given that much of its habitat is being altered rapidly and is becoming increasingly fragmented, the species is likely to be undergoing a continuing decline, at least in some parts of its global range. Over 90% of its very small global population has been suspected to be confined to one subpopulation (Amani Nature Reserve), and on this basis it is considered Critically Endangered, however recent research suggests that total numbers, while still small, are larger than previously thought, and that Mt Nilo holds a significant proportion of the population. If this is confirmed the species is likely to warrant downlisting.
