The transition from mountain forest to the shrub- and herb-dominated alpine tundra at higher elevations is very similar to the transition from the coniferous forest belt to the Arctic tundra at higher latitudes. Strong, frequent winds and cold temperatures help limit what plants can grow there. Big creatures, like this yak, highlight the need to keep the tundra. In tundra, labrador tea grows as ground cover or carpet. These flowers absorb energy and warmth from the sun and transmit it to the rest of the plant. For example, it developed a shallow root system that can only grow in the active tundra soil. This growth pattern is an adaptation that allows plants to resist the effects of cold temperatures. They grow and flourish in the growing season (summer) in the tundra biome. Above the Arctic circle, temperatures are so low that only animals and plants that have adapted to the climate can survive. Tundra biomes only receive 4-10 inches of rain annually. Arctic plants have a number of adaptations to the compressed growing season and low temperatures: They initiate growth rapidly in the spring, and flower and set seed much sooner than plants that grow in . And what makes things worse is that the very cold tundra weather turns rainfalls to snowfalls. Rather, the plant life above the Arctic circle is largely made up of very small plants growing close to the ground. Such adaptations are only possible in warm, humid climates.
