Which vegetation regions are found across the Namib Desert?

The Namib Desert is characterized by six distinct vegetational regions, each defined by its unique environmental conditions and moisture availability:1

• Coastal region: Features highly succulent vegetation that relies on moisture derived from fog.1
• Outer Namib: An area that is almost completely barren.1
• Inner Namib steppes: Typically barren, though they support a cover of annual and perennial short grasses during wet years.1
• Inner Namib dunes: Support a surprisingly rich flora consisting of tall grasses and bushes.1
• River channels: Larger channels provide enough water to support the growth of large trees, particularly acacias.1
• Southern winter rainfall area: Characterized by succulent bush growth.1

Additionally, the desert is home to the unique tumboa, or Welwitschia mirabilis, a plant known for its two gigantic leaves that sprawl across the ground. While the Namib is a fragile and sparsely covered environment, it contains complex flora adapted to its arid conditions.213
