Following removal of thickets of the invasive nonnative Chinese privet (Ligustrum sinense Lour.), two rare winter annuals, Corydalis flavula (Raf.) DC and Nemophila aphylla (L.) Brummitt, appeared at sites where they were previously unknown. Moreover, these sites in Clarke County were more than 100 km from the few previously known localities of the species in Georgia. Soil samples revealed that these sites were strongly divergent from typical secondary forests of the Piedmont with respect to pH, phosphorus, potassium, calcium, and magnesium (all significantly higher). It is possible, but unlikely, that these species were recently transported to these sites. It seems more likely that recent management activities stimulated seeds to emerge from a dormant seed bank.
