The Casuarinaceae family, commonly known as the she-oak family, consists of trees and shrubs primarily found in tropical and subtropical regions. These plants are characterized by their needle-like leaves and distinctive, jointed stems that resemble conifers, although they are not true conifers. They play a significant role in their ecosystems, often stabilizing soil and providing habitat for various wildlife. Members of the Casuarinaceae family, such as Casuarina and Allocasuarina, are known for their ability to fix nitrogen, which enhances soil fertility. They are often used in reforestation projects and as windbreaks due to their resilience and adaptability to different soil types.
