Citizen science is defined as participation of the general public in scientific research and has become a mainstream approach for collecting data on biodiversity.
This approach can substantially help scientists to address large scale or global biodiversity issues, through (1) monitoring the state of biodiversity by bringing a large amount of data needed for analysis and (2) the creation of indicators providing relevant information about state of biodiversity and public concern and action.
The development of citizen science is an opportunity for the general public to familiarize with scientific thinking and to improve their knowledge on specific subjects, which has been highlighted as one of the main motivations of participation.
More specifically, it is also a way to raise societal awareness about the stakes of biodiversity conservation. The participation to nature-based citizen science projects is also be a way to reconnect people with nature.
