The Agroforestree DatabaseAboutThe Agroforestree (AFT) Database was created in 2009 by the World Forestry Centre and provides specifics and selection guides on both native and exotic agroforestry trees. ContentThe database contains information about 600 tree species useful in agrofrorestry. Species descriptions include the tree's characteristics, ecology, native range, management, and agroforestry uses. The database is searchable by country, native or exotics species, products and/or services provided, and by the first letter of the species.

Tropical Forest Restoration within Galapagos National Park: Application of a State-transition ModelBackgroundFew restoration models address ecological and management issues across the vegetation mosaic of a landscape. Because of a lack of scientific knowledge and funds, restoration practitioners focus instead on site-specific prescriptions and reactive rather than proactive approaches to restoration; this approach often dooms restoration projects to failure. This synthesis article tests a state-transition model as a decision-making tool to identify and achieve short- and long-term restoration goals. Open access copy available |

Catalyzing native forest regeneration on degraded tropical landsbackgroundForest clearing, forest degradation, and the deterioration of land productivity due to inappropriate management is a major problem in the tropics. While traditionally, restoration of forest lands abandoned from human use has relied on natural forest regeneration, this paper explores the potential of plantations to catalyze forest regeneration in the tropics.

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 |

The Apparent Paradox of Reestablishing Species Richness on Degraded Lands with Tree MonoculturesbackgroundThis article discusses the use of tropical tree plantations as an approach to rehabilitation of degraded landscapes. For extremely degraded sites, the use of plantations may provide the proper shade, microclimate and protection for other species to colonize the understory. Research on the use of plantations in restoration is discussed, with examples primarily from Puerto Rico. Open access copy available |
