Marine Forests : Important Habitats Worldwide

Macroalgae, plants and animals like corals and sponges create complex habitats that provide resources, shelter and nursery grounds for many marine organisms.



Forests of macroalgae are mainly formed by large brown algae such as kelp or fucoids, but also by red and green algae (© Douglas Klug).


Seagrass meadows

Seagrasses are plants that evolved and adapted to live in the sea. They have roots, leafs and produce flowers and fruits (© Manu Sanfelix).


Animal gardens

Marine animal forests are mostly formed by invertebrates that live attached to rock, such as coral reefs and gorgonian gardens (© NOAA).

Help the world monitoring Marine Forests

Citizens worldwide are contributing with records of seaweed, seagrass, corals, sponges and other forest-forming species to reach worldwide maps with distribution records.
Explore all records
Taken underwater or at low tide, from herbarium and museum specimens, fragments on the beach, etc. Just provide the date and location, no need to identify the species.
The information you provide will be available for everyone in the world!
