Project

Forest management and regeneration of tree species in the Eastern Amazon

The pressure on the natural resources of the Brazilian Amazon has resulted in 20% of its original forested area shifted into pastures, secondary forests, or as degraded lands by 2006. A future use of an area depends on the decision of stakeholders, which is influenced by different multilevel forces that are better understood using the Competing Claims on Natural Resources approach.

Project description

One possible land-use option is to keep the forest stand for obtaining resources through forest management.  This option would become economically more viable if stakeholders would have access to silvicultural systems innovations that would guarantee sustained yields.  Although there are recent improvements on forest management, as reduced impact logging (RIL) techniques, new post-harvest silvicultural treatments to achieve sustainable harvests in the Brazilian Amazon are necessary.

In my PhD research I will be studying the regeneration ecology of commercial species to determine silvicultural treatments that would help moving towards ecologically and economically sustainable forested land-uses.  For fulfilling this general objective I will assess the resilience of Brazilian Amazonian forests to recover from RIL.  I also will assess the ecological and economic advantages of two silvicultural treatments applied in logging gaps to promote regeneration of commercial species.  Finally, I will foresee possible consequences of silvicultural systems innovations on stakeholders decisions on land-use in the Brazilian Amazon.
