Repeatable sampling methods that can automate and extend the scale and resolution of biodiversity monitoring are urgently needed to achieve robust estimates of long-term trends. The aim of ABMS is to evaluate methods using new technologies to monitor multiple species groups at a transnational (European) scale. More specifically, we will: a) Establish a coordinated, international acoustic and image-based monitoring network for insect, bird and bat species. b) Improve image recognition for insect species and sound recognition for birds and bats. c) Identify advantages and limitations of real-time species monitoring with these methods, and d) Demonstrate the workflow of sensor-based biodiversity monitoring.
