Abstract

Banksia elegans produces few fruits, and these only release their seeds in response to fire, depending on the temperatures reached by the follicles and subsequent number of wet-dry cycles. While 50% of intact seeds germinate in the laboratory, no seedlings were observed in the field. Despite the death of some old plants after a fire in a 15-yr-old stand, population size increased by more than 300% over the following 3 yr, entirely due to suckering from the parent lateral roots. Flowering of parent plants recommenced 3 yr after the fire, with most of the new suckers remaining juvenile longer. The pattern of ramet recruitment reflects that of genet recruitment by obligately sexually reproducing species in the region.
