The Sahel Acacia Savannas bioregion, located in the Sub-Saharan Afrotropics, consists almost entirely of one ecoregion — Sahelian Acacia Savanna [2] — that spans across the width of the continent from northern Senegal and Mauritania on the Atlantic coast to Sudan and Eritrea on the Red Sea. Commonly referred to as the ‘Sahel’—this ecoregion comprises a grassland-dominated transition zone between savanna woodlands to the south and the Sahara Desert to the north. The Sahelian climate is tropical, hot, and strongly seasonal. It also includes two very unique flooded savanna ecoregions — Inner Niger Delta Flooded Savanna [1], Lake Chad Flooded Savanna [3] — and altogether the bioregion as a land area of nearly 377 million hectares.

The Sahel Acacia Savannas bioregion is part of the Sub-Saharan Afrotropics subrealm and is made up of three ecoregions: Inner Niger Delta Flooded Savanna [1], Sahelian Acacia Savanna [2], Lake Chad Flooded Savanna [3].
