The tall grasses are used to the dry climate that's why they live there easily. There are many other kinds of plants there plus a variety of animals living there. However, the grassslands areas are rapidly dwindling due to two main things: global warming, which is changing the amount of percipitation they are getting and convertion to agriculture or worse, cities or urban areas. Plus pests are infecting the fields a lot. Pests, once they reach a field, they are able to multiply and spread rapidly, thus introducing the need for pesticides. A natural grassland makes it difficult for pests to seek out their host plants among the diversity; in addition, the natural grassland is host to a lot of predatory insects which further reduce pest populations. So when people destroy a natural grassland, they are allowing pest's population to grow. = = =  = = = = =//__ Other Info on Grasslands: __//= = · Grasslands receive about 30 inches of rainfall per year = = · The summers get so hot they sometimes catch the grass on fire = = · The winters are sometimes so snowy that snow is higher than your head = = · Many animals live in grasslands such as buffalos, elephants, rhinos, squirrel, giraffes, lions, cheetahs, mice, hawks, and many more = = · Prairies, as grasslands are sometimes called, have many beautiful wildflowers. = = · There are not many tall trees or bushes in the grasslands, because there is just not enough water for them to live. Also, there is too much wind on the prairie for tall trees to survive. = = **__ ANIMALS (Fauna):__** = = Zebras, Kangaroos, wildbeasts, impalas, cheetahs, bison, large herbivores, rhino,giraffes,antilopes, elephants, lions, ect., ect. = = __Locations:__ = = The planes of North America, the steppes of Asia, the savanas of Africa,and the pampas of South America and Australia. = =**__ LAND FEATURES (geography): __**= = Hills, small water holes, rocks, in savannah some huge rocks. = = __PLANTS(Flora):__ = = There are two main types of plants in plain grasslands are grasses and shrubs. In the savannah there are more trees than in the plains but there still there are not a lot. They also have grass everywhere wich is used to the lack of water, that is the only reason they survive. The Mongolian grasslands = = Mixed grasses: = = Mixed grasses have around 60-90 cm high and about 40-60 cm of rain each year. = = __// Work Cited Grassland. 2002. Photograph.
