General Information

Historically, the southern acornshell occurred in the upper Coosa River system and the Cahaba River above the fall line in Alabama, Georgia, and Tennessee. The most recent records for the southern acornshell were from tributaries of the Coosa River in the early 1970s, and the Cahaba in the 1930s (58 FR 14330). It was our determination at the time of listing, with consensus of the malacological community, that this species was likely to persist in low numbers in the upper Coosa River drainage, and possibly in the Cahaba River. Surveys of Coosa River tributaries have since been conducted by Service biologists, as well as Bogan and Pierson (1993a), Gangloff (2003), Johnson and Evans (2000), Pierson (1993, pers. comm. 1994), Williams and Hughes (1998), and others. Surveys of the Cahaba River have been conducted by Service biologists, Bogan and Pierson (1993b), McGregor et al. (2000), Shepard et al. (1994, 1998), Gangloff 2006, Johnson (in litt. 2006), and others. Despite these repeated surveys of historical habitat in the Coosa and Cahaba River drainages, no living animals or fresh or weathered shells of this species have been located in recent years. Recent authors have presumed the species to be extinct (Evans 2001, Gangloff 2003, Williams et al. in press). Considered extinct by many experts
