The chaparral biome is best characterized by large, contiguous regions of shrubland.
The chaparral biome is found in small parts of most of the continents such as the west coast of South America. The chaparral biome has various types of terrain such as flat plains, and mountain slopes. The chaparral biome is very hot and dry and it contains extremely large shrubs because the shrubs are able to survive on very little water. Other plants such as poison oak, Yucca Wiple and trees can be found in the chaparral biome. Animals of the chaparral biome include coyotes, praying mantis, and ladybugs.
