Spinifex grass is a type of tough, perennial grass found primarily in arid and semi-arid regions of Australia. It is known for its distinctive clumping growth form and sharp, spiky leaves, which can be quite abrasive. This grass plays a crucial role in stabilizing sandy soils and preventing erosion, making it an important part of its ecosystem. There are several species of spinifex, with Triodia being the most common genus. These grasses provide habitat and food for various wildlife, including insects and small mammals. Additionally, spinifex is often used in traditional practices by Indigenous Australians, who utilize it for thatching and crafting materials.
