According to edaphic features we can divide the Namib into three longitudinal sections which lie next to one another from the coast towards the highlands. These sections are the littoral sands, the barchan dunes and the consolidated sand to rocky soil surfaces of the plains. To these have to be added special biotopes such as the more hygrophilous or halophilous strata of river-beds, pans, etc. Keyword: Ecological divisions, Namib.
