Between 1991 and 2000, the total area of forest lost in the Amazon rose from , with most of the lost forest becoming pasture for cattle. Seventy percent of formerly forested land in the Amazon, and 91% of land deforested since 1970, is used for livestock pasture.

Amazonia is commonly dived into eight areas of endemism (districts): Napo, Imeri, Guiana, Inambari, Rondonia, Tapahos, Xingu and Belem.

With the progressive destruction of the rainforest comes a loss of habitats for many species of birds.
