Mangroves are also known as rich centres of biodiversity as they provide a home and shelter for many species including fish, birds, frogs, snakes, insects and several endangered crocodiles. Mammals also occupy these forests ranging from small animals like swamp rats and monkeys to large carnivores like tigers, that use the dense foliage as cover. Mangroves are also important nursery areas for many species of fish. Overfishing is a global problem and we are fishing at an accelerated rate without allowing fish stocks to recover; mangroves are therefore vital in providing breeding grounds for fish.
