Growing completeness of multi-taxon biodiversity occurrence information is associated with long-term socioeconomic advance in China

The absence of comprehensive species distribution data may hinder our understanding of biogeographic patterns and the development of effective conservation strategies. Although citizen science data on biodiversity present opportunities to address these data deficiencies, it also introduces various biases. Here, we conducted an analysis of the completeness of citizen science data and its driving factors in China to address existing knowledge gaps and offer new insights for biodiversity conservation research and practice.
