2. YELLOWSTONE NATIONAL PARK THE MAIN ECOSYSTEM IS TAIGA THIS ENVIRONMENT CONSIST OF MANY TYPES OF ECOSYSTEMS

3. The other Ecosystems are: Thermal Pond Freshwater lakes/ streams Grasslands Forest Most of the park is above 7,500ft. High Altitude means cooler temps. Temperatures in the Yellowstone National Park vary. Yellowstone is located in Wyoming, Montana and Idaho

9. MAIN ABIOTIC FACTORS Some main abiotic factors are weather, humans, and animals. Yellowstone has SHORT SUMMERS AND COLD LONG WINTERS THEY HAVE A LOTS OF WINTER STORMS.

10. More affecting Abiotic factors If the weather is to cold it can destroy plants, animals, trees. If the weather is to hot it can dry up water. Without water the animals, plants, trees can die. Pollution of all kinds (air, trash and vehicles) has affected the ecosystem of Yellowstone National Park by destroying streams, lakes and even animals are dying each day by man’s selfish choices.

11. HOW PEOPLE AFFECT THIS ECOSYSTEM People affect this ecosystem by creating POLLUTION. They do this with motorized cars and snow mobiles. This has increased the death of many animals. They have died from lung diseases and cancer.

12. OTHER PROBLEMS CAUSED BY MAN MAN HAS CAUSED MAJOR FOREST FIRES BURNING ACRES OF LAND. THEIR WAS A GREAT AMOUNT OF WOLVES BEFORE THE PARK WAS TAKEN OVER BY MAN IN 1872. IT MESSED UP THE FOOD CHAIN FOR A LONG TIME UNTIL THE PARK REINTRODUCED THE WOLF.

13. Other affecting Factors: Sounds of human activities can cause the animals to panic. Humans destroy the environment by taking from the park (small trees, plants, and animals) leaving an unbalance in nature. Trash…Brings animals closer to human population. It can cause death and sickness when the animals consume the trash.

14. What happened to bears and what they did Speeding cars injured and killed bears through out the night. Bears were killed near campgrounds and living areas. One adult female grizzly was killed in July, her cubs were held in captivity. A grown bear killed a man and injured two campers. By 1960s the western grizzlies couldn’t find their glory and forgot how to defend themselves. When the dumps were closed the grizzlies got aggressive.

15. What happened after the big attacks The grizzlies started getting their land back. People helped by putting the grizzlies in the endangered species act. The bears were given nine thousand square miles to regain their land. The bears went out in the woods to get their food. They struggled to go back to the brink. This is their land!
