A standard protocol for harvesting biodiversity data from Facebook

1. The expanding use of citizen science platforms has led to an exponential increase in biodiversity data in global repositories. Yet, our understanding of species distribution remains patchy for most of the world. Social media data has the potential to reduce the global biodiversity knowledge gap. However, practical guidelines and standardised pipelines to harvest such data sources are still missing. 2. Here, we provide a standardised framework to extract species distribution records from Facebook groups that allow access to their data following data privacy and protection safeguards. Facebook groups are actively used and moderated in some countries to share species records. We present how to structure keywords, search for species photographs, and georeference localities for such records. We further highlight…
