Assessment rationale/justification
This species is uncommon and restricted mainly to the mixed evergreen forests in the northeast and southeast of the country. Severe pressure on forest areas for timber extraction and due to many other anthropogenic factors its habitat is rapidly shrinking. Its Extent of Occurrenceis smaller than 5000 km2. Therefore, it qualifies for Vulnerable category.
