North Shore Road Wildlife Resources Survey

Diana Frittilary butterflyThe Catena Group was contracted in 2004 to conduct surveys for 16 target species within the proposed North Shore Road corridor in the Great Smoky Mountains National Park in Swain County, North Carolina. A total of six weeks were spent conducting inventories for streamside and aquatic salamanders, fish, crayfish, freshwater mussels, butterflies, and dragonflies. Aquatic survey methods used included electroshocking, sein netting, and snorkel surveys, Terrestrial and semi-aquatic survey methods used were time- and area-constrained visual surveys. Results of the survey were the documentation of 14 amphibian, 12 reptile, 27 fish, 3 crayfish, 51 butterfly, and 12 dragonfly species. Of the 16 target species, eight were documented to occur within the proposed corridor.
