. We must be talking about the Amazon, right? Wrong. It's the Atlantic Forest, which used to run in a continuous strip along the 2,000 miles of Brazil's eastern seaboard, up the steep coastal mountain slopes and, in places, far into the interior, reaching parts of Paraguay and northern Argentina.

This stunning image, with morning sunlight streaming through the canopy, gives a sense of the forest's magic and exuberance. In one part of the ecosystem, some 450 species of trees were once found in a single hectare (2.5 acres).
