Amazon biome Amazonas, Brazil contains campinarana, dense rainforest and contact between campinarana and rainforest. The vegetation formations include terra firme forests and igapós. Submontane forests climb the first steps of the Guiana Plateau to about , followed by montane forests. Lichens and bromeliads are found up to . There is also alpine tundra in the tabular plateaus. The Amazon basin contains several large areas of moist forest, collectively called the Amazon rainforest. These are the Caquetá, Japurá-Solimões-Negro, Juruá-Purus, Madeira-Tapajós, Napo, Purus-Madeira, Solimões-Japurá, Southwest Amazon, Tapajós-Xingu, Tocantins-Pindara, Uatuma-Trombetas, Ucayali and Xingu-Tocantins-Araguaia moist forests. Each has distinctive vegetation. In the broad definition favored by
Selective logging in the Amazon rainforest of the selective logging operations in the Amazon were illegal during the early 2000s. Since much of the logging practices were unregulated, high damage extraction operations rendered the forest land susceptible to drought and fire. In recently logged forests, canopy gap fractions are highest in log decks, however, the overall effect on forest gap fraction is negligible because of the decks small surface area. Selective logging in the Amazon rainforest Selective logging or partial forest removal is the practice of cutting down one or two species of trees while leaving the rest intact. Selective logging is often considered a better
