We’ve recently tried to be more clear about this in the FAQs, but citing iNat records from GBIF at all is a huge help, because it makes a link back to iNaturalist in a trackable and scalable way in the form of the citation tracker on the GBIF dataset. (Curators can help wordsmith this for clarity since the FAQs are a wiki page).
How should I cite iNaturalist?
Please cite a GBIF download! The easiest way for us to track research using iNaturalist is for you to download and cite a corresponding dataset from the Global Biodiversity Information Facility (GBIF). Once per week, research grade records on iNaturalist that are licensed for re-use are shared with GBIF. If you need additional records from iNaturalist that are not available from GBIF, you can also cite a dataset downloaded directly from iNaturalist. Citing a DOI for a GBIF dataset allows your publication to automatically be added to the count of citations on the iNaturalist Research-Grade Observations Dataset on GBIF.
