And grow back very fast at the beginning of the growing season (summer). It also limits foliage damage from the impact of tiny particles of ice and snow that sweep through the tundra, driven by the harsh winds. Lichens like mosses, need bogs and a high level of moisture to grow. With little sun, water evaporates slowly, making more available for plants or animals to use. All plants that live in the tundra have adapted to survive. There are few species with large populations. This perennial shrub is partial to well-drained riverbanks and steep, rocky slopes. Examples of Arctic vegetation include willows, poppies and purple saxifrage. mosses play an important role in the tundra ecosystem. The plant is distinct for its fluffy, cotton-like seed heads. Animals in the tundra are also adapted to extreme conditions, and they take advantage of the temporary explosion of plant and insect life in the short growing season. Sedges are grass-like plants.
