Justification of Red List category

Due to its small range and the degrading quality of the habitat it inhabits, which could potentially lead to food shortages during the year, and despite its stable population trend, this species is considered to have only one location. It therefore qualifies as Vulnerable under criterion D2. The population size is small, and also meets the thresholds for Vulnerable under the population size criterion D1.
For these reasons, this species is assessed as Vulnerable.
