Plants & Animals

In the rain shadow of the Rocky Mountains, the Great Plains are dry, windy and expansive. Receiving small amounts of precipitation, the land is dominated by grasses. The scarcity of water prevents larger shrubs and trees from growing. However, the soils are rich thus allowing a wealth of smaller plants to thrive. These plants, in turn, support a variety of animal species. Temperatures on the plains fluctuate enormously from very cold winters to hot summers. Nevertheless unique plant and animal adaptations have allowed life to prosper in plains ecosystems.
