Deforestation of the Amazon rainforest The completion of the roads was followed by a wave of resettlement; these settlers had a significant effect on the forest as well. Research conducted by Leydimere Oliveira et al. has shown that the more rainforest is logged in the Amazon, the less precipitation reaches the area and so the lower the yield per hectare becomes. Thus for Brazil as a whole, there is no economic gain to be made by logging and selling trees and using the logged land for pastoral purposes.

Amazonia is commonly dived into eight areas of endemism (districts): Napo, Imeri, Guiana, Inambari, Rondonia, Tapahos, Xingu and Belem. Although each area is similar in ecological characteristics, their biotas were assembled differently. With the progressive destruction of the rainforest comes a loss of habitats for many species of birds. As of today, over twenty percent of the original Amazon rainforest is gone, mostly as a result of deforestation and human encroachment. Human-made clearing has had important effects on bird species.
