Shade management in coffee and cacao plantationsBackgroundShade trees reduce the stress of coffee (Coffea spp.) and cacao (Theobroma cacao) by ameliorating adverse climatic conditions and nutritional imbalances and increase the biodiversity of coffee farms, but they may also compete for growth resources. This review summarizes the literature on ecological aspects of shade-grown coffee and cacao and on management of shade trees, but does not address economic and social aspects of shade-grown coffee and cacao.

Bwa Yo: Important Trees of HaitibackgroundThis book, published in 1996, presents important tree species in Haiti as part of a USAID effort to address environmental degradation in Haiti. The trees presented are mainly those in the agricultural landscape, providing food or fuel, although trees with cultural or ecological importance are also presented. Open access copy available |

Les légumineuses arborescentes dans les systèmes de production des zones sèches de Côte d'Ivoire (Arborescent leguminous plants in the production systems of dry zonesin Côte d’Ivoire)The authors saught to identify woody legumes adapted to dry conditions of Côte d’Ivoire and to determine their success in reforestation. They describe 18 species of woody plants that were successful seven years after planting while also noting several species that responded well to coppicing under tropical dry conditions.

Tree Canopy Management Affects Dynamics of Herbaceous Vegetation and Soil Moisture in Silvopasture Systems Using Arboreal LegumesBackgroundIt is important to understand how herbaceous and arboreal species interact with each other, specifically how shade effects understory plants. Silvopasture functions best when both strata of the forest are thriving. Silvopasture is impacted by species chosen, spacing of tree plantings, and other management practices. Tree legume species such as Gliricidia sepium and Mimosa caesalpiniifolia hold a potential value for commercial use while also fixing soil nitrogen in the soil. Open access copy available |

Screening trial of 14 tropical hardwoods with an emphasis on species native to Costa Rica: Fourth year resultsBackgroundCommercial forestry plantations have consistently relied on a limitd number of species, often favoring exotic species over native ones. This is mainly due to a lack of information or understanding related to the silviculture of native species plantations. This article uses a long-term experiement site in Costa Rica's La Selva Biological Station to work towards filling this knowledge gap. Available with subscription or purchase |
