Problem statement: Data associated with reintroduced and/or invasive wildlife species are often collected, but are not typically optimal for desired inference. So What? Why this research matters: The ability to formally make inferences about, and forecast, spreading wildlife populations is critical for guiding future monitoring efforts and understanding the mechanisms associated with their dynamics. Collaboration/Partners: This project is in collaboration with scientists at the National Park Service and U.S. Geological Survey. Research That Informs Decisions: Formal statistical models that account for the various sources of uncertainty in monitoring populations can be developed and fit to existing data to provide forecasts that can then optimally be used to guide future decisions about monitoring efforts.
