摘　　要：Background: As grasslands decline, grassland-dependent species such asgrassland butterflies have experienced widespread population losses. Tomanage remaining grasslands, prescribed fire, grazing, and haying are common management practices across the Southern Great Plains of the UnitedStates. However, the impacts of management and land use intensity (LUI) onbutterfly community composition and butterfly community traits are not wellunderstood. Additionally, local habitat characteristics such as vegetationheight and cover, as well as broader landscape categorization, including howmuch agriculture or urbanization is occurring around the habitat, can alterbutterfly communities.Methods: We conducted standardized butterfly and flowering forb surveys atgrassland sites across north-central Oklahoma.Results: LUI influenced overall butterfly community composition with sitesmanaged only with fire having the most dissimilar butterfly communitycompared to three other management regimens. The amount of agriculture,urbanization, and wetlands surrounding study sites also influenced butterflycommunity composition. Flowering forb community measures differed by sitewith sites managed by fire alone having lower blooming forbs species richness,diversity, and abundance than sites with other management regimens.Conclusions: Sites managed with only prescribed fire had the most disparatebutterfly community in comparison to other management methods, suggestingthat specialist butterfly species may be sensitive to increasing disturbance.
