North America in the United States, in Southeast South America in Uruguay and Argentina, and in Asia Otable tropical and subtropical grasslands include the Llanos grasslands of South America. Mid-latitude grasslands, including the Prairie and Pacific Grasslands of North America, the Pampas of Argentina, Brazil and Uruguay, calcareous downland, and the steppes of Europe.
There are two different kinds of grasslands: tropical and temperate. Grasslands in the southern hemisphere tend to get more precipitation than those in the northern hemisphere. Some grasses grow more than 7 feet (2 meters), and have roots extending several feet into the soil. Tropical grasslands are warm year round, but usually have a dry and a rainy season. In South America, they're called pampas. Central Eurasian grasslands are referred to as steppes, while in Africa they're named savannas. What they all have in common is grass as their naturally dominant vegetation. Grasslands are generally located between deserts and forests. The major temperate grasslands are located in central North America in the United States, in Southeast South America in Uruguay and Argentina, and in Asia along the southern portion of Russia and Mongolia. There are actually thousands of different kinds of grasses that grow in this biome. Where they grow usually depends on the amount of rain that area gets. In wetter grasslands, there are tall grasses that can grow up to six feet high. In dryer areas the grasses grow shorter, maybe only a foot or two tall. S.G. REYNOLDS. Grasslands in the wider sense are among the largest ecosystems in the world (Figure 1.1); their area is estimated at 52.5 million square kilometres, or 40.5 percent of the terrestrial area excluding Greenland and Antarctica (World Resources Institute, 2000, based on IGBP data).  LOCATION: The name for this biome, temperate grasslands, is a great description for what it is like here. The most important plants in this biome are grasses! Temperate grasslands have some of the darkest, richest soils in the world (not in wealth, but in nutrients). Trees and large shrubs are rarely found in grassland areas. There are many species of grasses that live in this biome, including, purple needlegrass, wild oats, foxtail, ryegrass, and buffalo grass. Many animals munch on these grasses, but they survive because the growth point on the grasses is very close to the ground. Temperate grassland. Temperate grasslands are characterized as having grasses as the dominant vegetation. Trees and large shrubs are absent. Temperatures vary more from summer to winter, and the amount of rainfall is less in temperate grasslands than in savannas. Grasslands are characterized as lands dominated by grasses rather than large shrubs or trees. In the Miocene and Pliocene Epochs, which spanned a period of about 25 million years, mountains rose in western North America and created a continental climate favorable to grasslands. Grassland biomes are large, rolling terrains of grasses, flowers and herbs. Latitude, soil and local climates for the most part determine what kinds of plants grow in a particular grassland. A grassland is a region where the average annual precipitation is great enough to support grasses, and in some areas a few trees.  Grasslands are areas where the vegetation is dominated by grasses (Poaceae), however sedge (Cyperaceae) and rush (Juncaceae) families can also be found. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (' ecosystem '), which is one of eight terrestrial ecozones of the Earth's surface. Notable tropical and subtropical grasslands include the Llanos grasslands of South America. Mid-latitude grasslands, including the Prairie and Pacific Grasslands of North America, the Pampas of Argentina, Brazil and Uruguay, calcareous downland, and the steppes of Europe. They are classified with temperate savannas and shrublands as the temperate grasslands, savannas, and shrublands biom Different kinds of grass grow in different areas of the grasslands. There are actually thousands of different kinds of grasses that grow in this biome. Where they grow usually depends on the amount of rain that area gets. In wetter grasslands, there are tall grasses that can grow up to six feet high. In dryer areas the grasses grow shorter, maybe only a foot or two tall.
