Definitions for "Amazonia"
The watershed of the Amazon River and its tributaries. Amazonia covers about 40 percent of South America (7,050,000 km²) – half rainforest and the rest savannah ("campo") or scrubby woodland ("cerrado"). Amazonia covers substantial parts of Bolivia, Peru, Guyana, Suriname, Colombia, Ecuador, and Venezuela, though most of the Amazon basin lies within Brazil. It is the largest tract of undeveloped forest and greatest single concentration of biodiversity in the world.
In the Pre-Crisis Golden Age period, Amazonia was the name of the original Greek Island home of the Amazons. After their subjugation by the God, Hercules, the Amazons relocated to Paradise Island.
