These biodiverse ecosystems are rich with nutrients and life! Mangroves are tidal swamps which are dominated by mangrove trees, which are highly adapted to thrive in salty water, and muddy low-oxygen sediments. Some mangrove species have “breathing” roots called pneumatophores, which rise above the water to absorb oxygen in oxygen-poor environments. Others can excrete excess salt through their leaves, allowing them to thrive in salty conditions. Mangroves protect coastlines by preventing erosion
