Australian Pine, also known as the Casuarina tree, is a fast-growing evergreen tree. The tree is named after its resemblance to pine trees that are usually found in the colder regions of the world. Apart from its common name, the tree is identified by various synonyms depending on its location and use. Some common synonyms for Australian Pine include horsetail tree, she-oak, and ironwood. The tree is widely used in coastal regions, landscapes, and coastal restoration projects due to its ability to tolerate salt and sandy soils. Its wood is also used in construction, as it is strong and durable.
