Landscape management can foster pollinator richness in fragmented high-value habitats

Pollinator diversity is declining due to habitat loss, low habitat quality, limited habitat connectivity, and intensification of agriculture in remaining high-value habitats within human-dominated landscapes, such as calcareous grasslands. Options to increase the local area of protected habitats are often limited. Therefore, we asked how local habitat quality as well as agri-environmental schemes (AES) and configuration of the surrounding landscape can contribute to the preservation of pollinator diversity. We sampled bees, butterflies, and hoverflies in 40 calcareous grasslands in Germany and assessed the effects of calcareous grassland area, quality and connectivity, agricultural configuration, and AES on species richness and abundance. While calcareous grassland area was an important predictor for bee and butterfly species richness, with strongest effects sizes for endangered species, local flower resources and nesting sites, and landscape characteristics such as small field size, hi..., , , # Landscape management can foster pollinator richness in fragmented high-value habitats

在人类主导的景观中，如石灰质草原（Calcareous grasslands）这类尚存的高价值生境，由于生境丧失、生境质量低下、生境连通性不足以及农业集约化加剧，传粉者多样性正持续下降。扩大保护生境本地面积的可行方案往往十分有限。为此，本研究旨在探讨本地生境质量、农业环境计划（agri-environmental schemes, AES）以及周边景观配置如何助力传粉者多样性的保护。
我们在德国的40处石灰质草原中对蜜蜂、蝴蝶和食蚜蝇进行了采样，并评估了石灰质草原面积、质量与连通性、农业景观配置以及农业环境计划对物种丰富度和个体多度的影响。尽管石灰质草原面积是蜜蜂和蝴蝶物种丰富度的重要预测因子，对濒危物种、本地花卉资源与筑巢位点以及小田块规模等景观特征的影响最为显著，但……
