Did you know that mangrove trees grow in saline or brackish water? They live close to the shore, so in high tide, almost half the tree is under water. Mangroves are extremely important species to both the oceans and us humans and unfortunately, about half of the world's mangroves have been devastated due to the farming of scampi and rural development.

By having a complex root system, creating a maze of roots and branches, the roots actually filter out sediment that comes with rivers and heavy rain before going out in the ocean. This is especially important for corals, which need clear water to be able to get most of their nutrients. Mangroves also support many different species (especially shark species) by creating a nursery-like area for juveniles, protected from many larger predators that can't hunt inside the root system. It also supports humans by preventing erosion and landslides, and in some countries, the wood is used as material for buildings and fires.

In the near future, Koh Tao Municipality will host a mangroves plating day between Assava and Ihasia in Chalok Bay. Keep your eyes open for upcoming dates and feel free to join if you've got some spare time!
