Amazon rainforest This constitutes the largest collection of living plants and animal species in the world. The region is home to about 2.5 million insect species, tens of thousands of plants, and some 2,000 birds and mammals. To date, at least 40,000 plant species, 2,200 fishes, 1,294 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region. One in five of all bird species are found in the Amazon rainforest, and one in five of the fish species live in Amazonian rivers and streams. Scientists have described between 96,660 and 128,843 invertebrate species in Brazil alone. The
Selective logging in the Amazon rainforest from initially low volume harvests of floodplains to much higher rates that remove around 25 million m3 of wood from the forest each year. The ecological, social, and economic impacts drive a better understanding of efficient forest management techniques. Logging in the Brazilian Amazon started when settlers came from Europe in the 17th century. Until the 1950s, logging was only allowed in floodplains around the main rivers and only in small portions. This changed as industrial mills started to populate the Amazon to produce sawn wood and veneer. These mills gained access to other areas of the Amazon through new
