In Argentina, 22 owl species (Tytonidae and Strigidae) have been recorded. The aims of this work were to identify the most important regions for owls in the country; to determine biological variables for a risk assessment; and to relate their conservation status to the degree of knowledge and habitat use. Based on species richness and the occurrence of threatened and range-restricted species, the most important regions for owl conservation are the Selva Paranaense and Yungas, followed by Chaco and Patagonia. High priority species for conservation are all subtropical forest inhabitants. For all these species only distributional data is available, while the most studied species are found in areas of lesser importance for the conservation. Having identified the high priority areas and species for conservation, priority lines for research are proposed.
