Mosses and Lichens: These non-vascular plants are the true pioneers of the tundra, colonizing bare rock and soil, creating a crucial microhabitat for other organisms. The most prominent examples are various species of mosses, liverworts, and two flowering plants: Antarctic hair grass and pearlwort.

Low Shrubs: Species such as dwarf birch and Arctic willow grow only a few inches tall, developing woody stems that provide structural support. This ecosystem is dominated by three primary growth forms that circumvent the challenges of wind, cold, and poor soil.
These Antarctic pioneers have developed incredible antifreeze proteins and slow metabolic rates to endure months of darkness. These organisms, from diminutive mosses to vibrant flowering shrubs, form the foundational layer of unique polar ecosystems, playing critical roles in nutrient cycling and supporting specialized fauna.

These forms include prostrate shrubs, rosette plants, and cushion plants, all of which hug the ground to avoid desiccating winds and trap heat near the soil surface. However, in the relatively milder coastal regions of the Antarctic Peninsula, a few hardy species endure.
