“…However, our research found benefits of incorporating fire and grazing in native rangelands. Cattle grazing is often reported to be disruptive to floral resource availability (Kimoto et al., 2012), but patch‐burn grazing helps to concentrate cattle in recently burned areas (Spiess et al., 2020), creating the necessary heterogeneity to support diverse pollinator communities (Kimoto et al., 2012; Hanberry et al., 2021; Samways et al., 2020). Our treatments likely needed additional time to develop, but they are predicted to increase land sharing between pollinators and livestock, similar to rangelands in Israel (Shapira et al., 2020).…”

“…Globally, grazing lands cover 2.6 billion ha (Henderson et al., 2015), and in the United States, rangelands account for 33% of all land area (Ma & Coppock, 2012). Rangelands can provide the necessary structural and vegetation diversity needed by multiple pollinator species in various life stages, especially when managed with periodic disturbances to create diverse plant communities (Hanberry et al., 2021). Historically, however, rangelands were predominantly managed for uniform livestock production (Ma & Coppock, 2012).…”

“…Increasing our ability to maintain livestock production while conserving pollinators in rangeland landscapes would be valuable in the future (Senapathi et al., 2015), but several obstacles preclude landowners and land managers from optimizing these two goals. Currently, we lack an understanding of the distribution, abundance, and trends of many rangeland pollinators and their necessary resources (Hanberry et al., 2021; Samways et al., 2020). Additionally, research is lacking on how rangeland management may interact with pollinators and their stressors (Hanberry et al., 2021).…”

Pollinator declines have driven research and increased monitoring efforts. Within North Dakota, USA, our research group initiated research in 2015 on pollinator conservation and management. We synthesized results across five projects, producing 12 publications and providing baseline data on pollinator diversity and rangeland management to improve conservation efforts while land‐sharing with livestock. We detected 76 species of butterflies and ∼318 bee species. Butterfly diversity and relative abundance were driven by floral resources and less exotic plant invasions, with a positive relationship between flowers and pollinators. Invasive forbs were visited by pollinators, primarily honey bees. We also found management influenced vegetation characteristics within pastures, but landscape context was important for determining the specific outcome. Although pollinator abundance did not distinctly respond to management, diversity was affected by regime and grazer type. Using fire and grazing may benefit flowers to support pollinators. Our research will help guide rangeland management decisions that promote land sharing and benefit pollinator conservation efforts. Core Ideas We synthesized pollinator data from research conducted over six years in North Dakota. Pollinator diversity correlated with more forb diversity and less invasive plant species cover. Pollinator diversity, not abundance, has variable responses to management regime and grazer type. Fire and grazing may benefit vegetation communities to conserve pollinators in some landscapes.

“…Fire can be an effective tool for controlling insect pests, pathogens ( Komarek 1970 ), and ectoparasites ( Stoddard 1957 , Barnard 1986 ). At the same time, moderation in the application of fire is advocated in some prairie ecosystems where fire sensitive insect species occur, especially rare arthropods ( Opler 1981 , Moffat and McPhillips 1993 , Hanberry et al 2020 ). It is likely important in the LLPE to consider temporal, spatial, and taxonomic resolution when examining the impact of fire on arthropods.…”

The longleaf pine Pinus palustris Miller (Pinales: Pinaceae) ecosystem once covered as many as 37 million hectares across the southeastern United States. Through fire suppression, development, and conversion to other plantation pines, this coverage has dwindled to fewer than 2 million hectares. A recent focus on the restoration of this ecosystem has revealed its complex and biologically diverse nature. Arthropods of the longleaf pine ecosystem are incredibly numerous and diverse—functionally and taxonomically. To provide clarity on what is known about the species and their functional roles in longleaf pine forests, we thoroughly searched the literature and found nearly 500 references. In the end, we tabulated 51 orders 477 families, 1,949 genera, and 3,032 arthropod species as having been stated in the scientific literature to occur in longleaf pine ecosystems. The body of research we drew from is rich and varied but far from comprehensive. Most work deals with land management objective associated taxa such as pests of pine, pests of—and food for—wildlife (red-cockaded woodpecker, northern bobwhite quail, gopher tortoise, pocket gopher, etc.), and pollinators of the diverse plant understory associated with longleaf pine. We explored the complex role frequent fire (critical in longleaf pine management) plays in determining the arthropod community in longleaf pine, including its importance to rare and threatened species. We examined known patterns of abundance and occurrence of key functional groups of longleaf pine-associated arthropods. Finally, we identified some critical gaps in knowledge and provide suggestions for future research into this incredibly diverse ecosystem.

“…However, it remains unknown if similar principles may broadly extend to pollinator assemblages, though some authors have recently investigated this idea (Filazzola et al. 2020; Hanberry et al., 2020). An understanding of how relationships between livestock grazing pressure, evolutionary history of large herbivore grazing and ecosystem aridity affect pollinator assemblages carries implications for global pollinator conservation and can help to prioritize rangeland management efforts.…”

A variety of habitat‐associated factors moderate effects of grazing on insect biodiversity. Here, we examine how aridity, evolutionary history of grazing and grazing intensity individually and interactively mediate the effect of livestock grazing on pollinator biodiversity (native bees and butterflies). Using a meta‐analysis of 59 studies published in the primary literature, we characterized the response of pollinator communities to grazing across several continents. In very humid habitats, high grazing intensities generally had negative impacts on pollinator abundance and richness, but these effects were not found in semi‐arid habitats, where livestock grazing intensity did not interact with aridity to impact pollinator abundance or richness. However, within semi‐arid habitats livestock grazing was associated with reduced pollinator richness in areas with short evolutionary histories grazing. Pollinator life history mediated effects of livestock grazing on pollinator communities: livestock grazing had negative impacts on richness of social bees and butterflies but not solitary bees, though abundances of all three pollinator categories were consistently reduced under livestock grazing. Our synthesis suggests that effects of cattle on pollinators may be driven by impacts on nesting habitats (e.g. soil compaction), rather than consumption or alteration of forb cover. Our collective findings have importance for coordinating grazing management and pollinator conservation efforts and help to distinguish how grazing practices could impact pollinator biodiversity across ecoclimatic regions.
