__CLIMATE __
 * Grassland biomes take up a large portion of the planet. There is more than one grassland- one is wet, and the other is dry; but, one thing that stays the same is the amount of rainfall they get per year. They get enough rain to support growth of grasses, but droughts often cause fires that prevent many trees from growing. Grass catches fire, but they grow in the opposing direction of the trees, so the roots are still there for the grasses to grow back. The soil of grassland is usually too thin to support a tree, and it doesn't have enough nutrients. **

__WHAT LIVES THERE? __
 * The original settlers of the United States discovered the grassland when they expanded westward to what is now considered Iowa, All the way to Arizona, also known as the Mid- West. When they found the grasslands, (called prairies at the time) they also discovered over 300 Different species of birds, over 80 different species of animals, and hundreds of different species of plants. **

__WHAT KIND OF GRASSLANDS ARE THERE? __
 * There are two main kinds of grasslands- tall grass, which are usually somewhat humid, and very wet, and short- grasslands, which are dry with warm summers, and cold, brutal winters. The taller grasses were first discovered around the Missippi River, on their journey westward, and the shorter grasses were around the mountains of the west. There is a very vast grassland that stretches from Ukraine, Russia, all the way to Siberia. This is a great example of cold, dry grassland. There isn’t any water near it for the grassland to receive moisture in any forum (precipitation, ect.) there are no winds, even though its right by the artic, the mountains block the brutal wind gusts from reaching the prairie. **

__THREATS TO THE BIOME __ @http://www.ucmp.berkeley.edu/glossary/gloss5/biome/ @http://www.blueplanetbiomes.org/world_biomes.htm @http://www.worldbiomes.com/
 * The biggest threat to this biome would probably be something not caused by human- Fires. This keeps from certain things from growing- as I said before, and there nothing there for the humans to harm, there’s no way for us to live in the grasslands, due to extreme conditions. **
