Short Abstract

ACT4BEES actively involves researchers and citizen scientists in studying the biodiversity of Apoidea and environmental quality in Trento. The results provide an essential foundation for future research and the implementation of policies aimed at protecting and conserving pollinators in the region.

Abstract

Pollinators are essential for biodiversity and ecosystem health but face threats from habitat loss, climate change, and pesticides.

ACT4BEES, funded by the European Union – NextGenerationEU, investigates the biodiversity and distribution of Apoidea, identifies habitats favorable to their survival, and assesses environmental quality through the analysis of pollen collected by Apis mellifera.

From April to July, with monthly sampling intervals, the MUSE – Science Museum, together with its project partners, conducted a survey across thirteen monitoring sites located within the municipality of Trento. In each site, an environmental monitoring station was established, equipped with two Apis mellifera hives for pollen collection and contaminant analysis, focusing on heavy metals and agrochemicals. In addition, two dedicated stations were set up for monitoring the biodiversity of Anthophila Apoidea. Entomological sampling was carried out in urban and peri-urban areas by citizen scientists using passive traps (pan traps), while in peri-urban and natural areas, entomological researchers performed sampling along standardized transects of known dimensions. To date, the project has collected over 900 Apoidea specimens belonging to five families and numerous genera. Multiresidual and palynological analyses of pollen samples revealed the presence of pesticides and heavy metals across all monitored sites. ACT4BEES actively involves citizens, and researchers, providing an initial knowledge base on wild bee diversity, floral resources, and environmental quality within the municipality of Trento. The findings represent an essential starting point for developing local land management strategies and for guiding future research aimed at the protection and conservation of pollinators in the region.
