The areas of land between desert regions and forests in temperate and tropical climates usually consist of grassland. Some grasslands contain mineral deposits and other useful materials. These have a rock outcropping to symbolize this and produce a Shield if worked in a city radius.
These fertile regions, covered with various types of vegetation, once occupied large areas of North and South America, Africa, and Eurasia. These areas are characterized by marked wet and dry seasons, with annual periods of drought. Although many types of grassland are naturally occurring, grasslands can also be created through deforestation of woodland areas. Grasslands are often cultivated and used as pastures and grazing lands. Because of the relatively low rainfall in these regions, the topsoil is high in nutrients. Grasslands are, therefore, well suited for growing crops, especially grain crops.
