Mangrove Facts

Mangroves are the only species of trees in the world that can tolerate saltwater. Their strategy for dealing with otherwise toxic levels of salt? Excrete it through their waxy leaves.

Blue carbon ecosystems (mangroves, sea grasses and salt marshes) can be up to 10 times more efficient than terrestrial ecosystems at absorbing and storing carbon long term, making them a critical solution in the fight against climate change.

Mangroves can drop 3 tons of propagules (seeds or sea pencils) per acre in a year.

Co-founder Charlie Russell searching for propagules.

White mangroves grow closer inland and their roots are underground and red mangroves grow closer to water and red mangroves don't have their roots in the ground. Red mangroves have their roots sticking up because red mangroves need their roots to have to breathe oxygen, black mangroves are the same but their roots are like spikes sticking up from the ground.

Red mangroves are sometimes called a "Walking Tree" because its roots advance out to the water one step at a time.

Mangroves’ dense root systems inhibit the flow of tidal water and encourage the deposition of nutrient-rich sediments. But once lost, mangroves are very difficult to replant due to shifts in the very sediments the roots helped keep in place.​​​

Mangrove forests — specifically, their thick, impenetrable roots — are vital to shoreline communities as natural buffers against storm surges, an increasing threat in a changing global climate with rising sea levels.

The United States has roughly 2,500 square kilometers (about 1,500 square miles) of mangroves — an area about the size of Luxembourg — located almost entirely in southern Florida.
