IUCN: Conservation Groups Launch Global Freshwater Fish BioBlitz, Inviting 'Citizen Scientists' to Help Monitor Fish Species


"Biodiversity change is complex to track because it happens everywhere. Citizen science is one of the most important approaches to provide data on the dynamics of biodiversity change, as it is possible to have observers in many places. BioBlitz initiatives help mobile citizen scientists to this task.
