Half of the known historical populations of Rhus michauxii have been extirpated in the last century. The few remaining populations are in a precarious position for a number of reasons, perhaps the most important of these being the species low reproductive capacity and its dependence on disturbance. The clonal nature of Rhus michauxii and the geographic isolation of the populations have led to low genetic variability. This situation is exacerbated by the fact that most of the populations do not contain plants of both sexes. The open, sunny habitat necessary for the establishment of Rhus michauxii was historically provided by fire, while today most populations are found in sites that are cleared artificially. Unfortunately these sitesroadsides, rights-of-way, railroads, agricultural fields and pine plantationsare under the constant threat of catastrophic disturbance. The status of this species depends heavily on our efforts to protect its habitat and maintain sexually reproducing populations.
