Bat Acoustic Monitoring Visualization Tool

Acoustic Monitoring

is essential for helping study and conserve bats in North America.

Throughout North America, bats are the primary predators of nocturnal flying insects, providing millions of dollars in pest control services annually. Bats occur in nearly every habitat on the continent, from high elevation alpine forests to deserts and neighborhoods within our largest cities.

Because bats fly in the dark of night, it is challenging to understand their behaviors and monitor their population status.

To get around this challenge, biologists use bat detectors to better understand bat ecology. These devices record the echolocation calls of nearby bats, and combined with specialized software and expert knowledge, biologists can often identify bat species from these detections. Biologists deploy these detectors for one or more nights at locations across the continent throughout the year, and may monitor presence or activity of various bat species each night.

Progress so far:

  • 29,815,505 total bat detections
  • 6,252,181 detections of 35 species
  • 238,998 nights monitored during 17 years
  • 2,792 detectors operated by 136 contributors across 44 states and provinces

Bat Acoustic Monitoring Portal

This application is a companion to the Bat Acoustic Monitoring Portal (BatAMP).

BatAMP provides a central platform where biologists can upload their detection data in order to better understand the distribution, seasonal movement patterns, and population status of bats across North America. These data are then compiled for visualization within this tool.

Bat Acoustic Monitoring Visualization Tool

This application enables you to explore bat monitoring data for 35 species across North America, allowing you to explore seasonal trends in species detections and explore bat activity for a particular location.

Explore detailed monitoring data for each of the species included in this application. Each species has a dedicated visualization page that enables you to:

  • explore seasonal trends in activity or detections for different locations around North America.
  • explore locations where the species has been detected compared to areas where the species was not detected.
  • filter the data to explore trends for a given state or province as well as a given time period or season. You are able to combine multiple filters for season, year, state / province, and more.
  • view detailed detection information for each bat detector.

Explore occurrence data aggregated across all species within this application. This allows you to:

  • explore trends in species co-occurrence.
  • see how many species have been detected at a given location based on sampling effort.
  • explore which species are detected in particular regions simply by zooming the map to the area you are interested in.
  • identify species mis-identification and information gaps.
Note: due to the methods involved in identifying echolocation calls to species, some species may be mis-identified may be present in the data used by this application. You should be particularly cautious with detections that are well outside the known range for the species.
