The continued survival of the Spring Creek bladderpod is threatened by habitat loss in its already limited range, as a result of rapid residential, commercial and industrial development (4) (5). Additional threats include conversion of land to uses other than cultivation of annual crops, such as to pastureland for grazing livestock, and encroachment of the plant’s habitat by woody and herbaceous perennials (4) (5). Unless a site is ‘disturbed’ in some way every few years, populations of this rare plant quickly dwindle, and agriculture has been the primary mechanism by which suitably disturbed habitat has been maintained in the recent past. However, agricultural practices within Tennessee’s Central Basin are declining as the demand for residential development increases. Furthermore, the associated construction of new and improved sewer, water and gas lines are often located along streams, precisely the habitat the Spring Creek bladderpod occupies. Any damning or alteration of the three creeks (Spring Creek, Bartons Creek and Cedar Creek) around which it lives pose a further potential threat to the species, since natural flooding is important in dispersal of seeds to newly disturbed sites (5).
