List of ecoregions in Yemen explained

The following is a list of ecoregions in Yemen, as identified by the Worldwide Fund for Nature (WWF).

Terrestrial ecoregions

Yemen lies on the boundary between two of the world's biogeographic realms. The Afrotropical realm covers the southeastern portion of the Arabian Peninsula, as well as Sub-Saharan Africa and Madagascar. The Palearctic realm covers the rest of the Arabian Peninsula as well as temperate Eurasia and Northern Africa.

Tropical and subtropical grasslands, savannas, and shrublands

• Southwestern Arabian montane woodlands (Afrotropical)
• South Arabian fog woodlands, shrublands, and dune (Afrotropical)

Deserts and xeric shrublands

• Arabian Desert (Palearctic)
• Arabian Peninsula coastal fog desert (Afrotropical)
• Red Sea Nubo-Sindian tropical desert and semi-desert (Palearctic)
• Socotra Island xeric shrublands (Afrotropical)
• Southwestern Arabian foothills savanna (Afrotropical)

Freshwater ecoregions

• Arabian Interior
• Southwestern Arabian Coast
• Socotra

Marine ecoregions

Yemen's seas are divided into three marine ecoregions, all part of the Western Indo-Pacific marine realm.

• Southern Red Sea
• Gulf of Aden
• Western Arabian Sea
