The decline in the monarch butterfly has led to it being considered for listing under the Endangered Species Act. Declines in managed and native bees have also been documented, leading to increased concerns about bee populations and communities, as well as the availability of pollination services for crops and native plants. Similar factors have been identified in the decline of monarchs, native bees, and other pollinators, including habitat fragmentation, loss, and degradation (including milkweed loss for monarchs), and disease/predation, as well as climate change, weather extremes, invasive species, and pesticides (e.g., Potts et al. 2010). The southern Great Plains has been identified as critical for conservation efforts for monarchs and other pollinators, and much of the habitat identified in this region for pollinator conservation consists of grasslands. With the extensive loss and fragmentation of native grasslands, managed grasslands are becoming increasingly important for supporting conservation efforts. Managed grasslands have the potential to provide floral resources for monarchs and other pollinators, as well as host plants (milkweeds) for monarchs and nest sites (e.g., undisturbed soil, woody or pithy stems, tree cavities) for native bees. However, few baseline data exist for this region, making it challenging to assess the value of ongoing conservation efforts for monarchs and other pollinators.
