Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019 Data Release

This data release contains the results from the North American Bat Monitoring Program's report titled 'Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019'. Specifically, these data include tabular data and geospatial data for the species-specific results related to the status and trends of 12 bat species at multiple spatial scales including: 10 km x 10 km grid cells, state/province/territories, and range-wide across the geographic extent of monitoring data for each species (i.e., across 'modeled species ranges'). They were produced using an analytical pipeline supported by web-based infrastructure for integrating continental scale bat monitoring data (stationary acoustic, mobile acoustic, and capture records) to assess the summer (May 1–Aug 31) population status and trends of North American bat species across their modeled ranges at multiple spatial scales. An occupancy model was estimated for each species while accounting for biases from false positives (i.e., misclassification error) and false negatives (i.e., detectability). Then, using the estimated relationships between grid cell occupancy probabilities for each species with ecological and spatiotemporal predictors, maps of species occupancy probabilities were produced for each year of sampling, for each NABat grid cell in each species’ ‘modeled range’. Finally, status and trends indicators across larger spatial extents (e.g. range-wide, state/territory/province) were derived based on the grid cell level occupa
