Vignette Bayesian Site Occupancy Model Bat Acoustic Data

Updated: Mar 27

U.S. Geological Survey Northern Rocky Mountain Science Center staff with the North American Bat Monitoring Program (NABat) have released a code vignette for application of a Bayesian single-season, single-species occupancy model for assessing silver-haired bat (Lasionycteris noctivagans) occurrence in Oregon and Washington. The vignette provides a walkthrough of reproducible code for applying the single-season occupancy model to bat occupancy data, as well as code and guidance for evaluating model fit and interpreting results of the fitted model.
