A Comparative Study of Tree Establishment in Abandoned Pasture and Mature Forest of Eastern AmazoniaBackgroundThis study compares seedling establishment, seed availability, seed predation, seedling herbivory, and abiotic barriers to tree establishment in recently abandoned pasture, treefall gaps, and mature forest understory in Pará State, Brazil.

Strategies for the Recovery of Degraded Ecosystems: Experiences from Latin AmericabackgroundThis paper reviews the rehabilitation potential of native species forest plantations in lowland Costa Rica, the Atlantic Forest of Bahia, Brazil, and sub-tropical Argentina. Native species can improve forest regeneration where soils are degraded and where sources of propagules are limited. While most tropical plantations are dominated by exotic species, native trees may be more appropriate because they are better adapted to the local environment, are already familiar to local farmers, and their propagules are locally available.

Public Awareness Generation for the Reforestation in Amazon Tropical Lowland RegionbackgroundThis study compares two plots of native tree species, one that was planted with small numbers of species representing potential natural vegetation and another that was planted with many species, including fast-growing pioneers. Research Goals & MethodsAfter 9 years, tree height, DBH, species composition, stand volume, tree density and species diversity were measured in both plots. Open access copy available |
Emerging Threats and Opportunities for Large-Scale Ecological Restoration in the Atlantic Forest of BrazilbackgroundThis article presents a policy model known as the Atlantic Forest Restoration Pact (AFRP) and discusses the vital role the Brazilian Forest Act and other legislation has played in preventing deforestation and encouraging reforestation.

Temporary Storage of Jussara Palm Seeds: Effects of Time, Temperature and Pulp on Germination and VigorbackgroundThe seeds of the jussara palm (Euterpe edulis) are recalcitrant and immediate sowing is not always possible after harvest; hence, research that examines the ability of the seeds to be stored and the effect of this storage on germination proves important.

How Successful is Tree growing for Smallholders in the Amazon?backgroundThis study compares donor-driven and smallholder-initiated tree growing projects in the Amazon to assess outcomes such as tree survival, commercialization success, and environmental benefits of two different approaches to tree planting. Such research is important for understanding the limitations of both smallholder and donor-driven tree growing for reforestation, and for improving production of forest products outside of natural forests. The study also emphasizes the importance of capturing local knowledge. Open access copy available |

Effects of Different Light Levels on the Initial Growth and Photosynthesis of Croton urucurana Baill. in Southeastern BrazilbackgroundThis study measures the effect of different levels of shading on growth, chlorophyll concentration, and photosynthetic rate of Croton urucurana, a pioneer species potentially important in reforestation efforts in riparian forests of Brazil. Research Goals & MethodsThe authors tested seedlings at 0% shade (full sunlight), 30% shade, 50% shade, and 70% shade. Open access copy available |
