What's New

The World Factbook has added a new “World biomes” field to the Environment section of the World entry. A biome is a biogeographical designation describing a biological community of plants and animals that has formed in response to a physical environment and a shared regional climate. Biomes can extend over more than one continent. While different classification systems define different numbers of biomes, the Factbook recognizes the seven biomes used by NASA: Tundra, Coniferous Forest, Temperate Deciduous Forest, Rainforest, Grassland, Shrubland, and Desert.

The new entry includes a World Biomes map, as well as photos and detailed descriptions of each of biome.
