The desert oak is a tree species known scientifically as *Allocasuarina decaisneana*. It is native to the arid regions of central and western Australia. This tree is well-adapted to dry conditions, featuring a unique appearance with slender, needle-like leaves that resemble pine needles. The desert oak can grow up to 10 meters tall and is often found in sandy soils. Desert oaks play a crucial role in their ecosystem, providing habitat and food for various wildlife. They are also important for preventing soil erosion in their native habitats. The tree's ability to survive in harsh climates makes it a symbol of resilience in the Australian landscape.
