Recording sounds in the forest makes it possible to identify animals based on their sounds and to quantify their occurrence. The method enables the systematic recording of birds in particular as part of monitoring tasks. This has only recently become technically feasible: the recordings require a lot of storage space; species identification using AI requires a lot of computer capacity. How these and other challenges can be solved is currently being investigated as part of the AkWamo acoustic forest monitoring feasibility study (link to project page: AkWamo) on the Britz intensive monitoring site (link to website: Britz intensive monitoring site) and on eight areas of intensive forest environmental monitoring, Level II (link to project page: Level II).
