Australian Pine
Casuarina equisetifolia
Australian Pine is an exceptional windbreak and firewood tree - actinorhizal nitrogen fixation, heartwood among the best firewoods in the world at roughly 5000 kcal/kg, and highly salt-resistant on poor saline ground - but it is hardy only to zone 9-12 and is a listed noxious and prohibited species across several US jurisdictions, making cultivation a legal question as much as a climate one wherever it is considered.
