It is native to the coastal regions of Australia, Southeast Asia, and the Pacific Islands. This tree is known for its ability to thrive in poor soil conditions and its use in coastal erosion control.

Description

Casuarina equisetifolia is a tall, evergreen tree that can grow up to 35 meters in height. The tree has a distinctive appearance with its long, slender, and drooping branchlets that resemble the equisetum or horsetail plant, hence the name.
