Growing Regions

Sheoak was introduced to the United States near the turn of the century [14]. It is widely distributed in southern Florida and is also found in California, Arizona, and Hawaii [12,17].

     

General Information

The scientific name for the sheoak genus is Casuarina (Casuarinaceae) [12,19]. Three species of sheoak are common in the United States. 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].
