Biodiversity databases are information systems storing information on biodiversity patterns, particularly those obtained through biodiversity informatics techniques. A list of biodiversity databases is available on Wikipedia. This category is designed to collect articles about the databases themselves rather than their managing organizations (for instance, eBird is a database, but the Avian Knowledge Network is an organization); however, organizations like GBIF whose databases don't currently warrant separate articles are fine for now. Taxonomic databases are also fine for now (since they show species diversity), but probably should move to their own category eventually.
