Biodiversity conservation is a global challenge that requires the integration of global and local data. Expanding global data infrastructures have opened unprecedented opportunities for biodiversity data storage, curation, and dissemination. Within one such infrastructure—the Global Biodiversity Information Facility (GBIF)—these benefits are achieved by aggregating data from over 100 regional infrastructure nodes. Such, regional biodiversity infrastructures benefit scientific communities in ways that exceed their core function of contributing to global data aggregation, but these additional scientific impacts are rarely quantified. To fill this gap, we characterize the scientific impact of the Atlas of Living Australia, one of the oldest and largest GBIF nodes, as a case study of a regional biodiversity information facility. Our discussion reveals the multifaceted impact of the regional biodiversity data infrastructure. We showcase the global importance of such infrastructures, data sets, and collaborations.
