Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(ii,iii,v); D ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01

The species is found in only one unprotected locality: Mt. Candalaga Range in Maragusan, Compostela Valley, where the individuals are distributed in small groups. A road infrastructure project is planned on part of the mountain. Moreover, the lower mountain slopes are being converted into banana plantations.

Given the small range, continuing decline in extent and quality of habitat, and the very small size of the population this species is listed as Critically Endangered.
