By the splendor of its landscapes, the strange beauty of its flora and fauna, and the deadly dangers of its mysterious undergrowth, the Amazon region has always crystallized the wildest dreams.
Whether the Amazon forest is enchanted or enigmatic, a “paradise” or a “green hell”, it is a unique part of the world with the diversity of its flora and fauna. It is home to almost half of all living species on Earth.
The Amazon harbors a phenomenal biodiversity: 40,000 species of plants, 3,000 species of freshwater fish, 300 species of mammals, 1,300 different kinds of birds, several million varieties of insects and more than 370 kinds of reptiles, that is to say one out of 10 of the known species on Earth. Added to this biodiversity are the 1,360 acres of dense forest, one third of the remaining tropical rainforests of the planet and 4,202 miles of winding rivers… So many factors that confirm the importance of the Amazon rainforest to the planet. Did you know that dozens of new species are being discovered every year?
The Amazon basin is the largest equatorial wetlands surface on the planet and the forest that covers it literally functions as the earth’s green lung.
The world’s largest river, the Amazon stretches along 4,179 miles and multicolored water from 1,100 streams run into it. With a flow output of 200,000 m³ per second, the Amazon River discharges a fifth of the planet’s freshwater into the ocean. The river is so wide that the effects of the tide can be felt 500 miles above the mouth of the river. When its waters meet the ocean in periods of strong tides, the shock produces a tidal bore, a fast and devastating wave, the Pororoca, which can be heard for miles around. 2,300 miles of the Amazon is navigable. Near to Manaus, the ocher water of the Amazon meets the black water of the Rio Negro. Their waters don’t mix in right away. They run along next to each other, ignoring one another, over several dozen miles, a magnificent sight to behold.
Its primary rainforest, with trees that measure 30 to 50m high, has the greatest levels of biodiversity. The trees of its canopy are so dense that they block out almost all of the light in the lower strata of the forest where a spectacular number of species thrive.
The forest can also spread over flooded land, often close to the river beds. The flooded forest makes up around 4% of the rainforest’s total surface area, and is often viewed on boat trips.
Amazon’s ecosystem also includes the mangroves that are found on the Atlantic coast but also the rocky mountains on the Guiana Shield. These highlands provide flora and fauna that are unique.
In regions of Brazil, such as Amapa, Roraima or even Guyana, the Amazon is also a savanna.
