Casuarina equisetifolia, Australian Pine (FOR298/FR366)

Figure 1. Australian Pine (Casuarina equisetfolia)Australian pine was originally planted in Florida in the late 1800’s as a windbreak and for shade. But soon thereafter it was spreading without help from humans. Today it is considered a category I invasive species in Florida, and the Division of Plant Industry strictly prohibits possessing, transporting, and cultivating this species. For those who find this tree in close proximity to their home, it’s a good idea to replace it since Australian pine is known to have a very low resistance to wind. Australian pine is commonly found growing on coastal shorelines since it thrives in salty, sandy environments. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012.
