2. Introduction Location: Wyoming Biome: Taiga Yellowstone national park is the first national park in America. John Colter, an European American person was the first person to describe Yellowstone. Yellowstone is best know for it’s beautiful sights.

3. Biome Biome: Taiga (Thai-ga) also known as the “Boreal forest” or the “Coniferous forest.” Major Characteristics: Thin layer of soil, Evergreen trees, cold weather, dry, and short growing season. Similar ecosystems: Russia, Siberia, Canada, Alaska, Finland, Norway, and Sweden.

4. Biotic Trees: Evergreen trees, Lodgepole pines, Quaking aspen trees fill the forests. Plants: Arrowleaf Balsamroot and wheat grass are found in meadows and forests, and wild huckleberries found in mountains. Birds: Dippers and Mallard ducks visits the ponds and streams for meals.

5. Animals The most abundant mammal: Elk. Yellow-bellied marmots and chipmunks live in the meadows and forests. Bighorn sheep lives on mountain cliffs. Bison and Pronghorn antelope live in the flat lands and in the northern section of the park, Bobcats and lynx are rarely seen.

6. Abiotic In Yellowstone National Park temperatures can reach up to 17.5 degrees Celsius or -4 degrees Celsius on average! It can get even colder! On average yearly precipitation is 3.13 Cm. Precipitation happens mostly in winter because it snows a lot.

7. Abiotic Yellowstone national park has a range of elevation from 5,282 to 11,355 feet. Yellowstone national park has a large area of 3,467 square miles long!

8. Abiotic: Seasons Yellowstone national park has four seasons. They are winter, summer, spring, and autumn. They have long winters but short summers, springs, and autumns.

9. Abiotic: Daylight hours DateDaylight hours January 21, 20139 hours and 31 minutes February 21, 201310 hours and 50 minutes March 21,201312 hours and 13 minutes April 21, 201313 hours and 43 minutes May 21, 201314 hours and 55 minutes June 21, 201315 hours and 25 minutes July 21, 201314 hours and 54 minutes August 21, 201313 hours and 41 minutes September 21, 201312 hours and 12 minutes October 21, 201310 hours and 44 minutes November 21, 20139 hours and 28 minutes December 21, 20138 hours and 56 minutes In winter there is very little sunlight In spring, and summer they have a lot of sunlight If you look at the equinox dates, the amount of daylight are almost the same. (1 minute a part) They experience all 4 seasons

10. How do these factors affect this ecosystem? Elevation affects the ecosystem by having less air pressure. Seasons affect this ecosystem by having fur and heavy coating of skin because taigas have long winters because they are up north. Animals have adapted to the cold weather. They have learned how to survive in the ecosystem.

13. Issues Winter grazing lands caused wolves in Yellowstone is going down dangerously small. As a result, the wolves are affecting the ecosystem such as elk, deer, and moose. Elk population is declining but now they are restored. Wolves are gone in Yellowstone.

14. Debate Ranchers don’t want the wolves because they are worried that they would find the cattle and sheep's easier than elk. Wolves are important to the ecosystem, without them the ecosystem is not complete. SupportOppose There are plenty of elk for wolves, they would not threaten humans or livestock. Wolves could get used to people and will start going to towns to look for food. Wolves are important to the ecosystem. As Population is increasing, hunting farther away form original spot.
