Data from: Divergent responses of native predators to severe wildfire and biological invasion are mediated by life history

This dataset supports an analysis of the relative and combined effects of severe wildfires and an early-stage barred owl (Strix varia) invasion on three native forest owl species in the Sierra Nevada, California, USA. Data were collected between 2018 and 2023 using a regional passive acoustic monitoring program, complemented by manipulative (lethal barred owl removals) and natural (severe wildfire) experiments. The dataset includes species-specific detection histories for flammulated owls (Psiloscops flammeolus), great horned owls (Bubo virginianus), and northern pygmy owls (Glaucidium californicum), as well as site-level covariates describing fire severity, barred owl removal treatment, topographic conditions, and survey effort. Derived variables include wildfire severity classifications and pre- and post-removal monitoring periods. The data can be reused to run Bayesian single-species "stacked" single-season occupancy models. All sensitive location information of forest owls has been omitted.
