There are only 24 populations left in New Jersey, Maryland, North Carolina and Virginia and the species is severely threatened. Some of the reasons for its decline are road, residential, commercial and industrial development, as well as water pollution, shoreline erosion and motorboat traffic. The rapidly growing human population along the mid-Atlantic coast is also causing problems because of the increased human water consumption in watershed areas.
