TUNDRA BIOME | What Is A Tundra Biome? | Tundra Region - YouTube Soil is scant, and plants growing in the tundra cling to life with a series of important adaptations including size, hairy stems and ability to grow and flower quickly in short summers. ASU - Ask A Biologist. The cool temperatures, short growing seasons, high winds and thin dry soil mean that this biome is a difficult place for plants to grow. The soil lacks the nutrients of richer soils in other ecosystems that are filled with organic material. Barren in the winter, the tundra in summer is awash with tiny alpine flowers that bloom in abundance; the landscape is green and lush with moss, lichens, sedges, grasses and dwarf shrubs. Predator populations and plant populations respond in kind to the peaks and crashes of the herbivore populations. There are no trees in the tundra. One of the most common plants found in the northern Arctic, moss campion is a variety of cushion plant, a slow-growing class of perennials that have adapted to hug the ground as they grow to form a cushion shape. They also have a root system made of runners that spread out over a wide area, allowing them to access water over larger surfaces.
