Interactions among Amazon Land Use, Forests and Climate: Prospects for a Near-Term Forest Tipping PointBackgroundThis study concerns the interaction of anthropogenic and natural threats on the Amazon forest and considers the possibility of a tipping point in the near future. The authors argue that the interaction of various factors may lead to a large-scale forest dieback, for example a deforestation of about 31% of the Amazon closed-canopy forest formation.

Seed rain under tree islands planted to restore degraded lands in a tropical agricultural landscapeBackgroundPlanting native tree seedlings is the predominant restoration strategy for accelerating forest succession on degraded lands. However, planting tree “islands” is less costly and labor intensive than establishing larger plantations and simulates the nucleation process of succession. Tree islands can attract seed dispersers to gradually spread restoration patterns from the islands. Restoration design can be informed by assessing the effect of potential planting arrangements on seed dispersal by birds and bats and determining the influence of surrounding forest cover.

Vegetation Structure, Species Diversity, and Ecosystem Processes as Measures of Restoration SuccessBackgroundThis article provides an example of how to evaluate forest restoration using integrative methods, including measures of vegetation structure, species diversity, and ecosystem processes. Specifically discussed are four measures of vegetation structure, four measures of species diversity, and six measures of ecosystem processes. Available with subscription or purchase |
Multiple-Use Forest Management in the Humid Tropics: Opportunities and Challenges for Sustainable Forest ManagementbackgroundThis report documents three regional assessments that were carried out between 2009 and 2012 to identify and draw lessons from on-the-ground initiatives in multiple-use forest management (MFM) in the Amazon Basin, the Congo Basin and Southeast Asia.

Ecological Restoration of Xingu Basin Headwaters: Motivations, Engagement, Challenges and PerspectivesBackgroundThis paper focuses on the Brazilian Amazon, specifically on the Xingu River Basin. It identifites deforestation as a threat to the Xingu River and a driver of environmental degradation. Open access copy available |
Finding the money for tropical forest restorationBackgroundForest in tropical countries have experienced significant changes due to human activity, shifting primarily to agricultural or urban lands. This change not only leads to loss of biodiversity but it also affects the supply of valubale forest products and ecosystem services. This study calls for a shift in rhetoric in forest restoration to go beyond a conservation agenda and to include economic benefits. The article discusses the economic dimensions of forest restoration to justify their claim, drawing heavily on experience in the Brazilian Atlantic forest. Open access copy available |
Biodiversity Persistence in Highly Human-modified Tropical Landscapes Depends on Ecological RestorationbackgroundThis paper shows how forest restoration can enhance biodiversity using case studies from the Brazilian Atlantic Forest. Open access copy available |
Effects of Fragmentation of the Atlantic Forest on Mammal Communities in South-Eastern BrazilBackgroundThe author presents a detailed analysis of the community of large and medium-sized mammals present in six remnants of the low Atlantic forest in Brazil. The six remnants had varying sizes: small (200 ha), medium (2,000 ha) and large (20,000 ha). The study seeks to (1) identify the mammal species richness and the relative abundance of individuals surviving in each reserve, and (2) analyze changes in the structure of the mammal community contrasting the relative abundances of orders and dietary categories between reserves of differing sizes.

The Cultural Context of Forest Degradation in Adjacent Purépechan Communities, Michoacán, MexicoBackgroundThis study aims to understand the relationship between cultural and ecological drivers contributing to change in forest land use patterns by comparing two adjacent indigenous communities in the volcanic plateau region of Michoacán, Mexico. The study suggests that both cultural and ecological processes must be studied together to best understand the cultural causes of forest change and accurately assess ecological consequences.
