This owl has a small population which is undergoing a rapid decline and severe fragmentation as a result of extensive deforestation. It therefore qualifies as Vulnerable.

- 2012 – Vulnerable (VU) –
- 2008 – Vulnerable (VU) –
- 2004 – Vulnerable (VU) –

|Population:||The population size is preliminarily estimated to fall into the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
Trend Justification: Dinagat has been almost totally deforested and rates of deforestation on Samar and Mindanao have been rapid, with virtually all remaining forest leased to logging or mining concessions. Hence, the species is suspected to be declining rapidly.
