Poa tussock is a type of grass native to New Zealand and parts of Australia. It typically grows in clumps, forming dense tussocks that can reach heights of about 30 to 100 centimeters. This grass thrives in cool, moist environments and is often found in alpine and subalpine regions. The plant plays a crucial role in its ecosystem by providing habitat and food for various wildlife. Its deep root system helps prevent soil erosion, making it important for maintaining soil health in its native habitats. Poa tussock is also used in restoration projects to help stabilize disturbed areas.
