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.

Otus stresemanni was formerly considered a distinct species following Marshall (1978), and it was treated as such in Collar and Andrew (1988). It has subsequently been treated as a subspecies of O. spilocephalus following Sibley and Monroe (1990, 1993), but this treatment is under review by the BTWG.
