A survey of the terrestrial mollusks of the Sipsey Wilderness Area, Bankhead National Forest, in northwestern Alabama was conducted from August 2003 to May 2004. A total of 15 sites were sampled across a number of different habitat and vegetation types found within the area. A total of 50 species were found, representing 14 families and 30 genera, including 58 new county and 2 new state records. This represents a significant increase in the known diversity of the area based on a preliminary survey conducted in the 1960s, which yielded only six species. The current survey highlights the need for more detailed survey work across Alabama and the southeastern United States.
