“…Our local diversity results are consistent with previous studies that have found increasing floral resource richness to be associated with higher bee diversity in both natural and restored habitats (Denning & Foster, 2018; Grundel et al., 2010; Potts, Vulliamy, Dafni, Ne'eman, & Willmer, 2003). Our results differ from other studies investigating landscape effects on bee communities in habitat plantings likely due to our focus on agricultural cover rather than on land cover known to be beneficial to bees (Denning & Foster, 2018; Ponisio et al., 2019; Rotchés‐Ribalta et al., 2018; Scheper et al., 2015). While agricultural area was strongly and negatively correlated with natural area in this study, not all natural areas may have been equally beneficial to bees.…”

“…Ecological restorations, such as grassland restoration, differ from pollinator plantings as their goal is to create new habitats similar to remnant habitats. Local and landscape factors can be important in shaping local bee diversity in pollinator habitat plantings (Scheper et al., 2015) and grassland restorations (Denning & Foster, 2018; Rotchés‐Ribalta et al., 2018). However, relatively little is known about bee community β ‐diversity across habitat restorations and how it is influenced by local and landscape factors (though see Ponisio et al., 2017).…”

1. Grassland ecosystems are imperiled by agricultural activity worldwide. Restoring grassland habitat is important to conserving grassland fauna and preserving ecosystem services, but more knowledge is needed on the impact that local and landscape factors have on patterns of diversity. We focused on whether prairie grassland restorations along a gradient of increasing agricultural cover in the surrounding landscape would be inhabited by less diverse and/or more homogenous native bee communities. Native bees are a specific target for many grassland restoration efforts, and supporting their local and β-diversity in reconstructed habitats is of mounting interest. We also investigated if higher floral resource richness within restorations could help ameliorate negative effects of agricultural landscapes. 2. We sampled 16 prairie restorations in Minnesota (USA) that varied along a gradient of increasing agricultural land cover around the site. We characterized floral resource richness at all sites beginning in mid-May and ending in mid-September. We used GLMMs and multivariate analyses to disentangle how floral resource richness and percentage of surrounding land cover in agricultural production are associated with the local and β-diversity of bee communities. 3. Local bee diversity increased with increasing local floral resource richness, independent of the surrounding landscape. Bee β-diversity was not impacted by local floral resource richness or percentage of agricultural cover in the surrounding landscape, indicating local and landscape factors are not substantially impacting the homogeneity of bee communities across restorations. 4. Synthesis and applications. We found that, regardless of agricultural cover in the surrounding landscape, more florally rich plantings attract more diverse bee communities. We recommend that habitat plantings prioritize local scale diversity, and that potential sites where the landscape is dominated by agricultural production should not be overlooked for restoration.

“…Floral communities are an important element of bee community dynamics (Biesmeijer et al, 2006;Lane et al, 2020;Mathiasson & Rehan, 2020), with prairie forb community composition being linked to bee community composition (Denning & Foster, 2018b;Tonietto et al, 2017). Differences in restored and remnant prairie plant communities may drive differences in bee community composition that can be explored through species-specific traits, specifically tongue length and floral specialization.…”

1. Grassland restoration is an important tool for conserving bee biodiversity within agricultural landscapes. Restorations foster increases in local bee abundance and α-diversity; however, these measures are insufficient for understanding whether remnant communities are being conserved. We compared native bee α-diversity, β-diversity and community composition between restored and remnant prairies in Minnesota, USA. We then investigated two potential drivers of bee community dissimilarity between restored and remnant prairies: proportion of agricultural land surrounding a restoration and differences in floral community between restored and remnant prairies.

“…Restoring pollination necessitates the explicit consideration of both plants and animals, yet previous restoration and research efforts have typically focused on one group [22,23]. Much of the literature on pollination restoration measures floral abundance and/or diversity [24] or pollinator abundance and/or diversity [25][26][27][28][29]. Assessing the recovery of pollinators and plants can be a useful first proxy for determining the effects of restoration on pollination.…”

Ecological restoration is increasingly implemented to reverse habitat loss and concomitant declines in biological diversity. Typically, restoration success is evaluated by measuring the abundance and/or diversity of a single taxon. However, for a restoration to be successful and persistent, critical ecosystem functions such as animal-mediated pollination must be maintained. In this review, we focus on three aspects of pollination within ecological restorations. First, we address the need to measure pollination directly in restored habitats. Proxies such as pollinator abundance and richness do not always accurately assess pollination function. Pollen supplementation experiments, pollen deposition studies, and pollen transport networks are more robust methods for assessing pollination function within restorations. Second, we highlight how local-scale management and landscape-level factors may influence pollination within restorations. Local-scale management actions such as prescribed fire and removal of non-native species can have large impacts on pollinator communities and ultimately on pollination services. In addition, landscape context including proximity and connectivity to natural habitats may be an important factor for land managers and conservation practitioners to consider to maximize restoration success. Third, as climate change is predicted to be a primary driver of future loss in biodiversity, we discuss the potential effects climate change may have on animal-mediated pollination within restorations. An increased mechanistic understanding of how climate change affects pollination and incorporation of climate change predictions will help practitioners design stable, functioning restorations into the future.
