Species

Justification
This species is known from forest habitats above 700 m on Mindoro and hence it is assumed to have a very small global range which probably supports a moderately small population. Declines are suspected owing to the on-going clearance of forest habitats, but the species is not restricted to a few locations and its habitat is not regarded as severely fragmented, thus the species is classified as Near Threatened.

Distribution and population
Otus mindorensis is endemic to Mindoro in the Philippines, where it is now judged likely to occur throughout the mountains in the centre of the island, and it appears to be common above c.1,000 m. The species was commonly observed recently in Mt Iglit-Baco National Park at 700-900 m.

Population justification
Although apparently quite common in suitable habitat, the area of remaining habitat is small and as a consequence, the population size is assumed to be moderately small also, with the number of mature individuals likely to be between 10,000-19,000. This equates to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.

Trend justification
The population is suspected to be in decline owing to on-going habitat destruction.

Ecology
It occurs in closed-canopy montane forest above 700 m. It has been recorded recently in patches of highly fragmented secondary forest within this elevation band.

Threats
Montane forest has been extensively cleared on Mindoro and is now greatly reduced in extent. Logging operations continue to clear remaining tracts and may pose a threat to this species.

Conservation actions underway
CITES Appendix II. It occurs in Mt Iglit-Baco National Park.

Conservation actions proposed
Compare population densities in fragmented and secondary forest with primary forest and determine the likely remaining population size and Area of Occupancy. Calculate rates of forest loss. Protect remaining tracts of forest on Mindoro for the benefit of this and a number of other threatened species.
