Abstract

Native bee communities in Arkansas remain poorly documented, particularly within fire-managed prairie ecosystems that provide critical habitat for pollinators. This study surveyed bee assemblages at two native prairie remnants in the Arkansas River Valley, one large (Cherokee Prairie Natural Area, CPNA) and one small urban fragment (Jewel Moore Nature Reserve, JMNR), both managed using prescribed fire. Using pan trapping, we recorded 599 individuals representing 96 species across 25 genera, including 49% singletons. Despite differences in size and landscape context, both prairies supported similarly rich bee communities per sample day, with JMNR and CPNA averaging 16.1 and 13.75 species, respectively. However, species composition diverged notably, with only 34.5% similarity, suggesting distinct community structure driven by site-specific habitat conditions and management histories. CPNA was dominated by large-bodied ground-nesting and cavity-nesting solitary bees, while JMNR supported smaller eusocial halictids and cavity nesters. Results highlight the value of prescribed fire in maintaining nesting substrates and floral resources. Even small, urban prairie remnants like JMNR can support high pollinator richness, emphasizing their role as conservation assets. Our findings contribute to a foundational baseline for native bee diversity in Arkansas and highlight the importance of both large and small fire-managed prairies in regional pollinator conservation planning.
