Populated Rangelands

Populated Rangeland is an anthrome that generally has fewer than 10 persons/km2 and nearly one quarter of all the pastured land on the planet.  There is little other land use and net primary production is low, in fact nearly half of the entire populated rangelands anthrome is represented by bare earth. 

This anthrome is frequently found throughout Africa, small regions in Asia, as well as regions in western North America.  Often represented by flat savanna, biodiversity in the populated rangeland anthrome is dependent on the area of the world and ranges, but is typically low.
