This species has been downlisted to Least Concern because it is no longer thought to be undergoing moderately rapid population declines, and is not thought to approach the thresholds for classification as Vulnerable under any other criteria. Nevertheless, the total population is thought to be moderately small and habitat loss remains a threat, and indications that the population is smaller than currently suspected, or undergoing rapid declines, would warrant reconsideration of its threat status.
