The mangrove (kulhi) on the north side of L. Maabaidhoo is a saltwater mangrove connected to the sea. Since it is linked to the sea, it acts as a nursery to multiple reef species. From the species of plants that have been recorded to grow in the mangrove and wetlands, Red Mangrove / Rhizophora mucronata (Ran’doo), and Ceriops tagal/ Yellow Mangrove (Karamana) are found here. Cleansing the freshwater lens of the island, preventing soil erosion and protecting the island from floods are some of the main functions of this mangrove and wetland area. Similarly, it acts as carbon sinks by storing carbon dioxide to reduce the effects of global warming. 
The seaweed in this area provides a great food source to turtles and is essential to their survival. In addition, this area acts as a carbon sink, and contributes to the breeding and growth of reef fish. The reef and seaweed area that surrounds this island are recorded to have a total of 6 types of seaweeds and 86 types of reef fish. L. Fushikandu is an atoll entrance (Kanduolhi) located on the northeast edge of Hadhdhunmathi. This area is rich with underwater life and is popular among divers. The reef life is known to breed and populate in this area. Some internationally endangered species, which are protected in the Maldives, that have been recorded to be seen in this area are Mobula Alfredi/ Reef Manta Rays (En’madi) and other types of rays, helonia mydas/ Green Turtles (Velaa), Eretmochelys imbricate/ Hawksbill turtles (Kahan’bu), and several types of sharks. Kanuhuraa and Fushirah are known to be used by seabirds as a space for resting and breeding.
