This derived dataset is based on occurrence records downloaded from GBIF for Guangdong Province, China. It includes all available occurrence records within the provincial boundary for three snapshot years: 2010, 2015, and 2020. Previously, many occurrence records were compiled manually with Python-assisted processing; in this dataset, all data are obtained directly from GBIF downloads following the official data citation workflow, so that all source datasets can be properly credited. Records were filtered by occurrence year (2010, 2015, 2020) and spatially restricted to Guangdong Province to support temporal analyses of biodiversity patterns.
