Brazil - September 29th, 2009

The Amazon River flows across the Brazilian state of Amazonas, east of Manaus. Towards the center, the large Lake Canaçari is visible near the upper banks of the river. Ninety-eight percent of the state of Amazonas is covered by rainforest. However, this delicate ecosystem is threatened by deforestation, such as that visible near the left edge of the image.

The rainforest is divided into three types of habitat: igapos, várzeas and low plateau. Igapos are permanently flooded lands, where the roots of vegetation are always submerged. Várzeas are higher than igapos; the land is only submerged when rivers are at their highest during the wet season. Finally, low plateau areas are higher still and thus never submerged. Much of the area of and around Lake Canaçari is várzea, as is the greenish area south of the lake and the river.
