Assessment rationale/justification
This species has a restricted distribution only in the mixed evergreen forests of northeast, east and southeast of the country. So, it is inferred that at least 50% of its population has been reduced due to the decline of its AOO, EOO, over the last two decades or so, unprecedented changes in habitat qualities and potential level of exploitation that are continuing unabated. It has been wiped out from its former range in the Sal forests (Khan 1987). Thus, it has been categorized as Endangered.
