Transcript of Taiga Biome
By Kelly Madden The Taiga Biome also known as the Boreal Forest Biome Temperature & Climate Winter temperatures range from -65 F to 30 F. Summer temperatures range from 30 F to 70 F. The Taiga is a moist subarctic forest. Sunlight Since the Taiga Biome is located in the northern regions, it may receive up to 20 hours of sunlight per day, during the summer. But, during the winter daylight is limited to just a few short hours. The long days and mild temperatures during the summer allow for rapid plant growth. But, this season only lasts for about 3 months. works cited http://www.brighthub.com/environment/science-environmental/articles/81812.aspx Precipitation Precipitation generally only reaches about 200-750mm each year. Which is usually rain in the summer, but sometimes is snow in the winter. Abiotic Factors Biotic Factors Producers Many of the Taiga biomes producers are trees. Some of these trees include the Balsam Fir, Jack Pine, Paper Birch and White spruce. Shrubs The Tiaga Biome doesnt have very much vegetation due to the harsh winters, but it does have few shrubs. Some popular shrubs are the soapberry and blueberry bushes. http://www.ehow.com/list_6617304_flowers-found-taiga_.html Animals Herbivores Some of the Taiga's herbivores are American Elks, Yellow Bellied Sapsuckers, Moose, and porcupines. Elk eat various types of plants and grasses, including sagebrush, pine needles, and beargrass. Yellow bellied sapsuckers drill holes in trees and eat the sap and insects drawn to it. Carnivores Some major carnivores in the Taiga Biome are Bobcats, wolverines, Gray wolves, and lynxs. Porcupines eat herbs, plants, roots, fruits and bark. Food Chain Omnivores Some major omnivores in the Taiga Biome are the American Black Bear, Northern Bat, and Chipmunk. Mooses eat shrub bark, grasses, branches, and aquatic plants. Chipmunks primarly eat seeds, nuts and fruits. Black Bears mostly eat grasses, roots and insects. Northern Bats mostly eat beetles, moths, and other insects. Energy Pyramid Human Impact http://en.wikipedia.org/wiki/Taiga http://www.blueplanetbiomes.org/taiga.htm Issues One of the biggest threats to the Taiga Biome is Clear Cutting. This is cutting down most of the trees in a given area, then replanting the forest using one species of tree during the following season. They then use the logs for toilet paper, newsprint, and lumber. Effects There are many negative effects that logging has on the Taiga Biome. First, without trees to hold the soil together, with heavy rain the soil can wash away and take years to get it back. Clear Cutting also destroys many animal's habitats. Also, by cutting down trees, some species of trees may become harder to grow and eventually become extinct. http://library.thinkquest.org/C0113340/text/impact/impact.taiga.pollution.html Plans for the future Many Nations are taking steps toward protection the Taiga Biome. There are new park reserves being created to keep the forest from any human interaction. Laws are also being made to prohibit logging, mining, and other forms of development in Taiga areas.
