Temperate grasslands are located throughout North America, Eurasia, Australia, and Africa. They are characterized by grasses as the dominant vegetation and lack trees. Temperate grasslands have hot summers and cold winters, with a growing season of 100-175 days when temperatures are above freezing. Common grass species include purple needlegrass, blue grama, buffalo grass, and galleta, while flowers such as asters, blazing stars, coneflowers, goldenrods, sunflowers, clovers, psoraleas, and wild indigos also grow. Animals that inhabit grasslands have adapted to the dry, windy conditions.
