Plant
Antarctic Hairgrass
Deschampsia antarcticaAlso known as Antarctic Hair Grass
Antarctic hairgrass forms dense, bright green cushions that thrive in the harsh polar conditions of the Antarctic Peninsula and surrounding islands. As one of only two native flowering plants on the continent, it relies on self-pollination and wind dispersal to spread across exposed rocky slopes. Its expanding range in recent decades serves as an important ecological indicator of warming regional temperatures.

- Very high
- Why interaction risk is low
- Safe to observe at a normal distance.
- What to notice
- Recognizable as low, dense tufts of fine green grass growing on exposed Antarctic soil and scree.
- Support conservation
- Follow all Antarctic Treaty visitor guidelines, stay on designated walking paths, and avoid stepping on vegetation.
Responsible observation
- Observation: Look for low tufts clinging to rocky, snow-free coastal ground during the polar summer.
- Biosecurity: Thoroughly clean boots and gear before landed visits to prevent introducing alien seeds.
