Of conservation concern.

Neviusia alabamensis has been recommended for federal listing under the Endangered Species Act. The species is known currently from five southeastern states; a population known earlier from Poplar Bluff, Missouri, has been extirpated (D. M. Moore 1956).

The disjunct populations appear to be relicts from a former more widespread distribution and perhaps were associated with mesophytic forests during the Tertiary (A. A. Long 1989). It also has been suggested that Neviusia alabamensis is an epibiotic taxon that survived the Mississippi embayment since the late Paleozoic or early Mesozoic (D. M. Moore 1956; D. D. Horn and P. Somers 1981).

Neviusia alabamensis has been cultivated as far north as Boston and Chicago since its discovery (J. R. Shevock et al. 1992). It has been misidentified as Physocarpus opulifolius (D. M. Moore 1956).
