The Amazon Tropical Tropical Jungle, The Forest With The Greatest Number Of Species On The Planet

By Dr. Vreugdenhil


The Amazon basin stretches across 9 countries with 2/3 in Brazil, 1/8 in Peru and 1/10 in Colombia, while the rest of the total of 7,000,000 square kilometers is found in Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. Almost all of the land continues to have forest.

The furthest origins of the Amazon river lie in Peru and Bolivia at a distance of some 6,500 km from the river mouth into the Atlantic Ocean. Because the lower Andes are rather hilly, the upper watershed of the Amazon have few lakes and creeks they are difficult to navigate, making those areas little accessible from the water. []

While average temperatures are close to 26 C, the daytime temperatures on a warm day run into the high 30s C. Rainfall falls throughout every season in the majority of the watershed, as it's primarily generated by convection: surface water evaporates and rises high into the sky, where it condenses and from where it falls back as rain. The snow capped mountains of the Andean Mountain Range add more water to the area.

The species variety is the greatest in the world: To date, at the very least 40,000 plant species have been registered for the Amazon region. Researchers have described between 100,000 |130,000 invertebrate species in Brazil alone. Some 2,000 types of birds and an estimated 430 types of mammals have been recorded, the majority of which are rodents and bats. Fishes are represented with about 2,200 species, while amphibians add up to over 425 varieties, and reptiles to some 380 species.

A study in 2001 showed that the tropical jungle in the Amazon of Ecuador has the greatest the greatest number of species. Studies performed inside the Cuyabeno Wildlife Reserve discovered more species per hectare than for any other area in the world. All this makes little difference to visitors, however, as even scientists while on an casual visit could not notice the difference in diversity.

To visitors The existence of slow flowing streams and lakes is a lot more important than extreme diversity of species. That is because, it is not easy to observe wildlife as it moves about high up in the canopies of the trees. To the observer on the ground, wildlife moving about through the tree crowns is difficult to see, because the contrast between the light of the sky and the leaves blinds a persons vision, making the leaves look almost black. Observation from narrow rivers, on the other hand, is much better, because light shines onto the lower branches and shrubs where many animals perch. But areas with slow flowing streams and lakes are rare in the Andes countries, and just the Cuyabeno Wildlife Reserve boasts such conditions. []

Only around 30 minutes flying and 1 1 / 2 hour by bus over a good asphalt road, Cuyabeno, is South America's most accessible Amazon park. This is why travelers on Tripadvisor elected the Cuyabeno Lodge among the best 25 destinations in all of Latin America and the greatest choice for Amazon tours.
