The Western Amazonian bioregion, located in the Southern America (Neotropical) realm, stretches north from Bolivia to the Amazon river in Peru, contained by the Andes Mountains to the west. It consists mostly of moist and seasonally flooded tropical forests, but also incorporates savanna to the south that is encircled by forest. The bioregion contains four ecoregions – Iquitos Várzea (469), Southwest Amazon Moist Forests (505), Ucayali Moist Forests (512), Beni Savanna (565) – and includes the western mainstem of the Amazon River, the Ucayali River, and several lakes in the South. The total area of this bioregion is approximately 111 million hectares.

The Western Amazonian Forests & Plains bioregion is part of the Amazonia subrealm and is made up of four ecoregions: (1) Ucayali Moist Forests (2) Iquitos Várzea (3) Southwest Amazon Moist Forests (4) Beni Savanna.
