Above the ground, various types of insects, birds and mammals take refuge. The brackish water allows both marine and freshwater aquatic animals to survive. While the forest provides refuge, the animals’ activities in return benefit the plants in several ways. Burrowing animals especially the Crustaceans enhance oxygen penetration into the wet soil. Insects such as honeybees and butterflies act as pollinators.
Being the last mangrove forest in the centre of the Kota Kinabalu city, KK Wetlands provides shelter for many faunas including snakes, mudskippers, many types of crabs, fishes and breeding site for the horseshoe crabs.
