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. A September 2016 Amazon Watch report concludes that imports of crude oil by the US are driving
Selective logging in the Amazon rainforest ground damage but log decks and roads were small components of the overall ground damage. However, different harvest methods and techniques result in different ground damage levels. Despite similar harvest techniques, conventional logging methods produce more ground damage than reduced impact logging. Selective logging is one of the many land uses in the Brazilian Amazon, but it also increases the human access to forests through the development of a multitude of logging roads. These roads allow easier access to logging sites but also make it easier for hunters to access forest land which reduces the biodiversity within the forest. Also,
