This project investigated aspects of the biology and ecology of rubber bush (Milkweed; Calotropis procera) that is invasive across northern Australia and parts of South Australia. Field observations and trials combined with laboratory experiments and modeling studies were conducted to improve our understanding of its biology and ecology. Rubber bush produces large numbers of seeds that are wind dispersed. It mainly invades disturbed sites and recruits new pollinators as it extends its range. It resprouts prolifically when cut or damaged by fire. Check out our publications to get more information on this introduced invasive plant.
