Bats and Owls Inventory at Devil's Postpile National Monument
Blakey R. Bats and Owls Inventory at Devil's Postpile National Monument. 2022. National Park Service
For its size, Devils Postpile National Monument supports a diverse assemblage of nocturnal fauna. Our summer 2022 surveys recorded 15 bat species within the monument. Five of these species had not been previously confirmed in the monument, including two of the three sensitive species targeted: pallid bat (Antrozous pallidus) and fringed myotis (Myotis thysanodes). No California Spotted Owls (Strix occidentalis occidentalis) were confirmed, but a Great Horned Owl (Bubo virginianus) was recorded. Across the disturbance categories of interest identified by monument leadership (e.g., high, moderate, and low levels of fire and blowdown disturbance), there was little variability in bat species richness, total activity, or individual species occurrence. Sites with moderate levels of disturbance recorded the most species and highest levels of activity compared to high and low disturbance, and both priority species were recorded within all three disturbance categories.
