Data underlying the publication: Scarcity of flowering plants on Sedum roofs limits pollinator diversity

This study investigates how green roof characteristics and surrounding landscapes influence pollinator diversity and abundance in urban areas. Researchers collected ecological data on pollinators (bees, wasps, hoverflies, and butterflies) using pan traps and hand netting across 25 green roofs categorized as sedum roofs, nature roofs, and roof gardens. The dataset includes measures of species richness, abundance, and functional diversity, alongside roof-level variables (flower diversity, vegetation cover, microrelief, roof size, height, and age) and landscape factors (percentage and proximity of surrounding green space). The research aims to identify which factors most strongly shape pollinator communities, providing evidence-based guidance for designing pollinator-friendly green roofs.
