The North American Bat Monitoring Program in the Pacific Northwest

The Bat Hub coordinates the NABat monitoring effort in Oregon, Washington, and Idaho by working with state, federal, tribal, and other partners.

Welcome to the Northwest Bat Hub Monitoring Results Viewer!

  • This interactive map will be a useful tool for those who are looking for detailed lists of bat species composition in a given area in the Pacific Northwest or those who want to follow the results of our collaborative monitoring.
  • The data in this tool combines our confirmed acoustic detections with historic range maps and predictive models. Use this viewer to explore findings and extract species lists and other results. For more information about our sources, see below.
