Species Characteristics
Biomass Growth and Farmer Knowledge of Inga edulis in Peruvian AmazonbackgroundThis study develops an equation for diameter-based biomass estimation of Inga edulis. The tree is widely grown in the Peruvian Amazon as a naturally occurring early-successional tree and in small farms and gardens for fruit and fuelwood. Open access copy available |
Shade effect on coffee production at the northern Tzeltal zone of the state of Chiapas, MexicoBackgroundShade-grown coffee has been a preferred method in the tropics largely due to its benefits for biodiversity. However, impacts on yield are not yet fully understood, nor are the potentials for multiple uses of canopy species. Open access copy available |
Optimising Seedling Management: Pouteria sapota, Diospyros digyna, and Cedrela odorata in a Mexican RainforestbackgroundThis study compares the height growth of three native tree species (Pouteria sapota, Diospyros digyna, and Cedrela odorata) during the first two years after transplantation from a nursery in three plot types (primary rainforest, secondary forest, and open pasture) in Veracruz, Mexico. Research Goals & MethodsThe effects of canopy closure, leaf nutrients, initial seedling height and seed mass on the final height of the plant after two years were analyzed.

Evaluation of Trees Indigenous to the Montane Forest of the Blue Mountains, Jamaica for Reforestation and AgroforestrybackgroundThis study investigates local knowledge of native species and their uses in agroforestry systems, as well as the establishment of native species in the Blue Mountains of Jamaica. Research Goals & MethodsInterviews were conducted with 27 local participants to determine the use of 80 taxa of trees and shrubs, 43 of them native taxa; the value of each species was calculated for 10 uses.

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.

Silvicultural and economic aspects of pure and mixed native tree species plantations on degraded pasturelands in humid Costa RicaBackgroundReforestation of degraded land in tropical regions provides one means of restoring ecosystems and improving rural livelihoods. Most plantations in humid tropical regions are established in pure plots using few species of high commercial value, generally exotics. This study compares growth and economic viability of native trees in pure and mixed plantations on degraded land. Available with subscription or purchase |
Tropical Dry Forest Recovery: Processes and Causes of ChangeBACKGROUNDThis paper aims at unraveling processes and pathways of tropical dry forest (TDF) secondary succession occurring after traditional shifting-cultivation practices. It focuses on the study of community dynamics, the development of forest structure, and changes in floristic composition, to understand what makes a group of species to be present, dominant, and eventually disappear, at a certain space and time. The work begins with a section on the use of tree rings to determine the ages of fallows. Open access copy 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 |
Agroforestry for Ecosystem Services and Environmental Benefits: An OverviewbackgroundThis article reviews research on the ecosystem services and environmental benefits of agroforestry, focusing on the following: 1) carbon sequestration, 2) biodiversity conservation, 3) soil enrichment, and 4) air and water quality.

Restoration of a Sri-Lankan rainforest: Using Caribbean Pine Pinus caribaea as a nurse for establishing late-successional tree speciesBackgroundIn the moist tropics, studies have demonstrated poor seedling establishment of late-successional trees on lands cleared of forest. This study examines the potential for establishing late-successional tree species that dominate the canopy of rainforest by planting within and adjacent to experimental openings that were created within a Pinus caribaea plantation.
