Biome In The Alpine Tundra

The alpine tundra is truly an amazing biome. I chose it because I am fascinated by the series of mountain ranges around the United States. One day I hope to climb to their peaks and experience this biome for myself. The flora and fauna native to this biome are truly built to survive the harsh cold and high altitudes with little oxygen, little heat, and lots of wind. Many of the plants are low to the ground and many of the animals native to this biome have long fur coats surrounding a layer of fat. Abiotic factors play a massive role in plant distribution in this biome. The abiotic factor of extreme cold and gusty winds makes it difficult for trees or any tall plants to grow. Most plants have adapted to grow close to the ground. When plants are closer to the ground they can absorb any warmth they can from the earth and stay out of the wind. The Bureau of Land Management (2008) explains, “Because the habitat of alpine vegetation is subject to intense radiation, wind, cold, snow, and ice, it …show more content…

Due to the conditions there isn’t one dominant plant species in this biome. However, most plants are low to the ground with large rhizome and root biomasses. According to Alpine Plant Life: Functional Plant Ecology of High Mountain Ecosystems (2003), "The roots and rhizomes not only function in water and nutrient absorption but also play a very important role in over-winter carbohydrate storage”. For example, the cushion plant, which looks like a large clump of moss, is really a plant that only grows to be less than an inch tall to avoid the cold winds. Other plants instead of being the typical green color, are red. The red colored pigments allow the plants to turn all of the light energy at high altitudes, into heat. It is remarkable that in this harsh biome, there are any plants at all. However, plants have adapted and now are able to thrive in these harsh
