The document discusses the challenges of ecoacoustics which it groups into three categories: scope, scale, and speed. For scope, it lists identifying various levels of acoustic information from taxonomic groups to individual animals and their behaviors. For scale, it discusses expanding monitoring to larger areas with more sensors and integrating projects into an infrastructure. For speed, it notes real-time identification is not always needed but could help with issues like poaching, biosecurity, and timber monitoring beyond airborne sounds.
