A Bayesian sensitivity analysis applied to an Agent-based model of bird population response to landscape change

► We use an Agent-based model (ABM) to explore the impacts of set-aside removal on Skylarks in Denmark. ► Our novel BACCO sensitivity analysis of an ABM is both rapid and thorough. ► We identify an influential input parameter that requires more rigorous parameterization. ► We analyze and distill some of the complexity of an ABM.
