Population justification: The species's density in suitable habitat has been crudely estimated at 1 individual per km2 in suitable habitat (F. Angulo Pratolongo in litt. 2007). The area of suitable habitat around known sites is c. 2,800 km2 but may be much larger. Hence, the population is estiamted to fall within the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: The range has contracted in the past and unquantified population declines are suspected to have occurred, owing to habitat loss and degradation.
