Longleaf pine savannas are one of the most threatened ecosystems in the United States. Cataloging the flora and fauna is important for protection and management. Up to 70% of the plants in savannas have been suggested to be insect pollinated. To assess relative abundance and richness of potential pollinators, we surveyed the bees found in an upland longleaf pine savanna and a wet pine flatwood savanna in eastern Louisiana. Bees were collected at three locations per site every three weeks from May until October using malaise and flight intercept traps as well as by hand collection. Preliminary results indicated much greater diversity in upland compared to wet savannas. Ramifications of these differences are discussed.
