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 |
Cattle and Weedy Shrubs as Restoration Tools of Tropical Montane RainforestbackgroundIn abandoned Latin American pastures, grasses often inhibit the establishment of woody species. This study tests the effect of cattle grazing on woody and herbaceous vegetation establishment in pastures of P. clandestinum and M. minutiflora. Available with subscription or purchase |
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 Structure and Composition of a Tropical Dry Forest Landscape After Land Clearance; Azuero Peninsula, PanamabackgroundThis article describes natural regeneration that has occured in five different habitat types in the Azuero Peninsula of Panama. These habitat types include active pasture, 2-yr abandoned pasture, 5-yr abandoned pasture, forest riparian zones, and a secondary forest fragment. This region is characterized by agricultural and cattle ranching landcapes in areas that previously were tropical dry forest (1700 mm rainfall per year) until the mid-20th century and have recently been undergoing rapid turnover in land ownership.

The Role of Animal Seed Dispersal in Accelerating Native Forest Regeneration on Degraded Tropical LandsbackgroundThis article reviews the role of seed-dispersal in forest regeneration. In natural forest, species with animal-dispersed species tend to predominated in both early and mid-stages of succession, while wind-dispersed species tend to be vines and canopy species. The implications of wind versus animal seed dispersal are briefly summarized. Available with subscription or purchase |
Early Growth of Native and Exotic Trees Planted on Degraded Tropical PasturebackgroundThis study describes the potential of two exotic and five native tree species to restore degraded land in Costa Rica. Research Goals & MethodsThirty blocks were established over 25 hectares of abandoned cattle pasture and tree height was measured at 3 and 7 years and tree survival was measured after 7 years.

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 |
