Mangroves along Western Africa.
 
On the western coast of Africa, The Gambia, Casamance, and Saloum Rivers flow into the Atlantic Ocean. April 6, 2020.
 
From North to South, the Saloum River, Gambia River and Casamance River cut into the western side of Africa. The photo is turned so that North points to the right of the image. Text, The Gambia River flows approximately 1,100 kilometers, 700 miles from the southeast to the northwest. It marks the center of the smallest country in mainland Africa, The Gambia.
 
Lines appear on either side of the Gambia River.
 
Text, The dark green areas along the banks of these three rivers and in the estuaries are mostly mangroves, coastal forests that thrive in brackish waters.
 
Mangroves provide timber resources as well as storm and erosion protection for coastal communities.
 
Compare the landscape along either side of the Gambia River in this photograph from the International Space Station.
 
To the south of the river, left, the view is far greener. Southern Senegal and The Gambia have dense woodlands, savannas, and wetlands.
 
Senegal to the north and south of The Gambia.
 
Text, To the north of the river, right, the region appears much brighter due to the exposure of bare soil and a lack of visible vegetation.
