Assessment of pollinator diversity and abundance on National Wildlife Refuges and other private and public lands in the lower Mississippi Alluvial Valley of Arkansas to integrate pollinators and native emergent wetlands/moist soil management areas into a decision making context


May 2016 - January 2017


Wetlands have not previously been surveyed for bee species richness or bee community dynamics. National Wildlife Refuges and other public lands manage wetland complexes for primarily waterfowl but these wetlands could harbor diverse and abundant bee communities. We surveyed a series of public and private wetlands in Arkansas to document bee species richness and the relationship between those bee communites and wetland management.
