Feasibility of Farmer-Managed Vegetative Propagation Nurseries in CameroonbackgroundThis article reviews farmer-managed vegetative propagation nurseries in Cameroon. The authors summarize the division of costs required to establish and operate the nurseries. Research Goals & MethodsCuttings of Dacryodes edulis, Irvingia gabonensis and Ricinodendron heudelotti were studied. All had successful rates of propagation by cutting, but only Dacryodes edulis had success with air layering. Open access copy available |
Participatory Domestication of Agroforestry Trees: An Example from the Peruvian AmazonbackgroundThis paper describes a program through the International Centre for Research in Agroforestry (ICRAF) to work with farming communities to domesticate native tree species for use in agroforestry and the conservation of tree diversity in their forests.

Uses, Management, and Economic Potential of Dacryodes edulis (Burseraceae) in the Humid Lowlands of CameroonbackgroundThis article discusses the economic potential of a African rainforest fruit tree, Dacryodes edulis. The fruit is locally consumed and traded, in addition to its household value for oil and medicinal bark. Available with subscription or purchase |
Uses, Management and Economic Potential of Garcinia kola and Ricinodendron heudelotii in the humid lowlands of CameroonBackgroundThis article describes two common fruit and medicinal trees (non-timber) that grow in secondary forests in the lowlands of Cameroon. The trees are found to have a mixed effect in an agroforestry environment; sometimes they improve crop production, sometimes they do not. Fruit are consumed by families and sold in markets.

Domestication of Dacryodes edulis: State-of-the-artBackgroundThis article provides an overview of the work being done to domesticate Dactryodes edulis, a fruit tree widespread to the humid lowlands of Central Africa. It focuses on a program in Cameroon coordinated by ICRAF that is based on a participatory approach of domesitcating D. edulis. Open access copy available |

Amelioration of degraded rain forest soils by plantations of native treesbackgroundWhile much has been studied about the ability of tree growth to improve degraded soils in temperate zones, less is known about the impacts of tree growth on degraded soils in tropical zones. research goals & methodsThis study looks at the effects of trees planted in abandoned pasture land in northeastern Costa Rica, 25 years after that land had been cleared of rainforest. The soil was sampled before tree planting and 4 years after the trees became established. Available with subscription or purchase |
Tree species effects on soil properties in experimental plantations in tropical moist forestBackgroundForest soil properties are influenced by the complex interactions of vegetation, soil type, geology, management, and climactic patterns. Tree species can differ in their long-term effects on soils. This study resamples one of the earliest replicated experimental sites at La Selva Biological Station, Costa Rica, used to examine the effects of native tropical tree species on soil properties, to examine longer term effects on soil properties.
