What is a Grassland?
A grassland is a grassy, windy, partly-dry biome, a sea of grass. Almost one-fourth of the Earth's land area is grassland. In many areas, grasslands separate forests from deserts. Deep-rooted grasses dominate the flora in a grassland; there are very few trees and shrubs in a grassland, less than one tree per acre. There are many different words for grassland environments around the world, including savannas, pampas, campos, plains, steppes, prairies and veldts.
There are two types of grasslands, including:
Tropical grassland - hot all year with wet seasons that bring torrential rains. Located between the Tropic of Cancer and the Tropic of Capricorn, sometimes called savannas.
Temperate grasslands - hot summers and cold winters. The evaporation rate is high, so little rain makes it into the rich soil. Located north of the Tropic of Cancer and south of the Tropic of Capricorn.
Animal Adaptations: The animals that live in grasslands have adapted to dry, windy conditions. There are grazing animals (that eat the grass), burrowing animals, and their predators; insects are abundant. A moderate of level species diversity exists on a grassland.
Where are Grasslands? Grasslands are located in North America's interior (called prairies), in southeastern South America (Argentina's pampas and the campos of Uruguay and Brazil), in Eurasia (the Eurasian steppe in Mongolia and parts of the former Soviet Union), in Africa (the semi-arid steppes of the Sahel of north-central Africa and the wetter grasslands, veldts, of East Africa and Madagascar), and in Australia and New Zealand (called rangelands).
Animals that Live in Grasslands: Many animals live in grasslands, from invertebrates (like grasshoppers and beetles) to large mammals (like antelopes and bison). The different grasslands of the world support different populations of animals.
Africa - aardvark, African wild cat, African elephant, many antelopes, baboon, buffalo, Cape hunting dog, cheetah, giraffe, gnu, hartebeest, hippopotamus, hyena, impala, jackals, kudu, leopard, lion, meerkat, mongoose, oryx, ostrich, red-billed oxpecker, rhinoceros, vulture, wildebeest, zebra, and many other animals.
Australia - dingo, emu, kangaroo, wallaby, wombat, and many other animals. Many non-native animals have been introduced, including the camel, donkey, goat, horse, rabbit, and sheep.
North America - American toad, badger, black-footed ferret, bison, black-tailed jack rabbit, bumble bee, burrowing owl, California condor, carrion beetle, common snipe, coyote, deer, dragonfly, eagles, eastern cottontail, elk, ferruginous hawk, fox snake, golden owl, gopher snake, grasshopper, gray wolf, ground squirrels, killdeer, lady beetle, larks, long-billled curlew, meadow vole, monarch butterfly, northern grasshopper mouse, prairie chicken, prairie dog, prairie rattlesnake, prairie skink, pronghorn antelope, red fox, red-tailed hawk, shrew, skunk, stink bug, tiger beetle, western meadowlark, western tiger swallowtail, white-tailed jack rabbit, and many other animals.
