The species appears to have a small range which is severely fragmented and continuing to decline in extent, owing to widespread destruction and degradation of its forest habitat. The total population size is unknown but could be small, given the species's apparently very patchy distribution within its range. At present the species is treated as Vulnerable until improved information on its population and distribution becomes available.
