Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008

Listed as Data Deficient as the threat level of this subspecies will depend very much on its extent of occurrence, which at this time is unclear due to lack of clarity as to where is was found historically and where it persists today. If the subspecies was found in the eastern portion of its proposed range then it would likely classify as Endangered, as the area has been burned extensively and is severely degraded. If it never occurred in this eastern area then the extent of occurrence is well protected and might be considered Vulnerable or Near Threatened. Further surveys and clarification are necessary to further assess the subspecies.
