General Information

All will be treated in this report because of their similar status as invader species and across-the-board management plans to eradicate the genus from the continent. These species are [6,19]: Casuarina cunninghamiana Miq. river sheoak Casuarina equisetifolia L. Australian-pine Casuarina glauca Seiber gray sheoak These species hybridize with each other [14].
