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.

本研究探讨了城市区域内绿色屋顶特征与周边景观如何影响传粉者的多样性与丰度。研究者采用碗型诱捕器（pan traps）与手持网捕法，在25座被划分为景天屋顶（sedum roofs）、自然型屋顶（nature roofs）与屋顶花园（roof gardens）三类的绿色屋顶上，采集了涵盖蜂类、胡蜂、食蚜蝇与蝶类在内的传粉者生态数据。本数据集包含物种丰富度、丰度与功能多样性的相关测度指标，同时涵盖屋顶层面变量（花卉多样性、植被覆盖度、微地形、屋顶规模、高度与使用年限）以及景观因子（周边绿地占比与邻近程度）。本研究旨在明确对传粉者群落塑造作用最强的影响因素，为设计适配传粉者的绿色屋顶提供循证指导。
