This research examines the effectiveness of protected areas in preserving forest cover in the Brazilian Amazon. It addresses the risks and challenges faced by protected forests and explores factors impacting their integrity and biodiversity. The study also analyzes the impact of roads on deforestation and the network of protected areas in the region.

Christopher P. Barber, South Dakota State University, christopher.barber@sdstate.edu • NASA Biodiversity and Ecological Forecasting Team Meeting, May 7th 2009 Research Questions Are Protected Areas in the Amazon Working? Are protected areas preserving the natural forest cover? What levels of risk are protected forests facing? Can we say something about the integrity of remaining forests? Risks?
