This species is listed as Least Concern as its range is known to be much larger than was once thought, and does not approach the thresholds for Vulnerable under the IUCN criteria. Its population size and trend are also not thought to approach the thresholds for Vulnerable; however, both its population and range are still thought to be declining and it is recommended that the species be closely monitored.
