On the protection of “protected areas” [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
Tropical moist forests contain the majority of terrestrial species. Human actions destroy between 1 and 2 million km 2 of such forests per decade, with concomitant carbon release into the atmosphere. Within these forests, protected areas are the principle defense against forest loss and species extinctions.

Protecting the Amazon with protected areas [PDF]

open access: yesProceedings of the National Academy of Sciences, 2009
This article addresses climate-tipping points in the Amazon Basin resulting from deforestation. It applies a regional climate model to assess whether the system of protected areas in Brazil is able to avoid such tipping points, with massive conversion to semiarid vegetation, particularly along the south and southeastern margins of the basin.
