responses of pollinators to urbanization and local management in urban farms in Havana

This database contains information on flower visitation and insect assemblages collected in 16 urban farms (organopónicos) in the Cuban provinces of Havana and surrounding areas. Data were collected during 2023 and 2024 and include information on flower abundance, insect abundance, and species richness, as well as records for specific insect groups: Syrphidae, other Diptera, Coleoptera, Lepidoptera, large bees (Xylocopa, Centris), small bees (other Cuban Apidae genera, Halictidae, Megachilidae), Apis mellifera, ants (Formicidae), and wasps (Vespoidea). The database comprises 16 farms, including Organopónico Raquel Pérez, Labranza, Oro Verde, Vivero de Alamar, Hermanos Gómez, Esfuerzo Colectivo, El Girasol, CIMEQ, Arides Estévez, Arcoiris, 5to Congreso, 24 de Febrero, 1ro de Julio, Cooperativa 1ro de Julio, Playa, and Luyanó. Data for Organopónico Luyanó in 2023 and Hermanos Gómez in 2024 are not available due to lack of sampling. In addition to biological data, the database includes climatic variables (monthly minimum and maximum temperatures, and precipitation) recorded from July 2022 to June 2024, which allow analysis of environmental influences on flower visitation and insect community structure. Overall, the database provides detailed records on flower abundance and insect community composition across two years, enabling studies of temporal and spatial variation in pollinator communities in urban agricultural landscapes. Each record is linked to the farm and sampling year, with consistent taxonomic classification and standardized abundance metrics for comparative analyses.
