Mangrove forest, Senegal

Although we think of forests as trees on land, some of the most important trees grow in water, or more precisely marshland. Mangrove forests, like this one in Saloum Delta National Park in Senegal, are vital components of the world’s coastal ecosystems. Mangroves survive where no other trees can, in salty, low-oxygen coastal waters exposed to tides and storms. They grow up to nine metres high primarily in tropical and subtropical regions and can store vast amounts of carbon, making them crucial to moderating our climate. Mangroves also act as nurseries for fish and aquatic life. And with their complex interwoven root system, they protect coastlines from erosion.
