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 selective logging in tropical forest disturbance. Although selective logging has a far less impact on forest processes than deforestation, selectively logged sites experience higher rates of forest fires, tree fall, changes in microclimate, soil compaction and erosion, among other ecological impacts on biodiversity and ecosystem functioning. Selective logging is a dominant form of land use in the Brazilian Amazon. Canopy gap fractions patterns are found to result from selective logging caused tree falls, roads, skid trails, and log decks, which are areas where logs are staged for transport. These gaps can vary between logging operations. Logging activities has now increased
