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.

Selective logging in the Amazon rainforest of the selective logging operations in the Amazon were illegal during the early 2000s. Since much of the logging practices were unregulated, high damage extraction operations rendered the forest land susceptible to drought and fire. In recently logged forests, canopy gap fractions are highest in log decks, however, the overall effect on forest gap fraction is negligible because of the decks small surface area. Selective logging in the Amazon rainforest Selective logging or partial forest removal is the practice of cutting down one or two species of trees while leaving the rest intact. Selective logging is often considered a better
