Amazon biome
ecological region of South America
The Amazon biome (Portuguese: Bioma Amazônia) contains the Amazon rainforest, an area of tropical rainforest, and other ecoregions that cover most of the Amazon basin and some adjacent areas to the north and east. The biome contains blackwater and whitewater flooded forest, lowland and montane terra firma forest, bamboo and palm forest, savanna, sandy heath and alpine tundra. Some areas of the biome are threatened by deforestation for timber and to make way for pasture or soybean plantations.
Location
The Amazon biome has an area of 6,700,000 square kilometres (2,600,000 sq mi).
The biome roughly corresponds to the Amazon basin, but excludes areas of the Andes to the west and cerrado (savannah) to the south, and includes lands to the northeast extending to the Atlantic ocean with similar vegetation to the Amazon basin.
J. J. Morrone (2006) defines the Amazonian subregion in this broader sense, divided into the biogeographical provinces of Guyana, Humid Guyana, Napo, Imeri, Roraima, Amapá, Várzea, Ucayali, Madeira, Tapajós-Xingu, Pará, Yungas and Pantanal.
The World Wildlife Fund takes a similar scope, where the Amazon biome includes the Guiana Shield rain forests in the north and the Chiquitano dry forests of Bolivia.
The biome covers parts of Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname and French Guiana.
In Brazil the biome covers more than 4,100,000 square kilometres (1,600,000 sq mi) and covers all or parts of the states of Acre, Amazonas, Roraima, Rondônia, Pará, Amapá, Maranhão, Tocantins and Mato Grosso.
The Amazon biome covers 49.29% of Brazil.
The public source identifies “Amazon biome” as ecological region of South America. This brief keeps that definition visible, then builds a research path around Amazon, biome and ecological.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Amazon biome”, the useful work is to connect “ecological region of South America” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Nov 5, 2025. The linked authority identifier is Q29017821. Authority coordinates are -2.970, -64.600. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
