sunny Most of the Great Plains region has a semiarid climate, with a wide range of temperature and little rainfall. The semiarid climate does not provide enough precipitation to support trees in much of the region where the natural vegetation is mostly grassland, but in northern regions the summers are short and cool and the sparse precipitation is enough to support a coniferous forest.
