The Delta is one of the most biodiverse places in the world. A wide variety of habitats have emerged within the Delta, both terrestrial and marine. Mixed tropical forests, where huge palm trees prevail that prevail over much of the mainland, with a great variety of flora including fruit and palm trees, orchids, bromeliads and ferns; the latter proliferate in the humid air of the tunnel formed by the thick foliage.

 

The swamps and bogs are full of aquatic plants and the estuaries that go to the ocean are covered with mangroves. Throughout the entire Delta, the rivers themselves have totally different shapes, the wide channels becoming small streams, lagoons and isolated pools. Some, full of sediments, are brown, others black due to the effect of tannic acids. Many are covered with huge floating meadows of bora (water hyacinth) and floating grasses, which are slowly washed away with the current.
