What are the characteristics of grassland climate?

Temperate grasslands have cold winters and warm summers with some rain. The grasses die back to their roots annually and the soil and the sod protect the roots and the new buds from the cold of winter or dry conditions. A few trees may be found in this biome along the streams, but not many due to the lack of rainfall.
