Tropical Wet Forest
Rehabilitation of Degraded Tropical Forest LandsbackgroundThis article discusses the options for the rehabilitation of degraded land on high rainfall areas. It suggests that it is both environmentally and economically disadvantageous to let the degraded land remain in an unproductive and rapidly eroding state. Available with subscription or purchase |
Restoration of Tropical Forest EcosystemsBACKGROUNDThis book presents a compilation of papers presented at a symposium on "Restoration of Tropical Forest Ecosystems" that occurred in Bonn, Germany during October of 1991. The event, sponsored by Mitsubishi Corporation, addressed the reasons for tropical forest destruction, opportunities and challenges for restoration, rehabilitation and management. This book presents perspectives of authors from different countries and contexts on forestry, ecology, and nature conservation to address the need for restoration and rehabilitation of tropical forests.

Ecological Significance of Crown Functional Traits Across Size Classes and Disturbance Environments in Eight Pioneer Species in a Sri Lankan Rain ForestbackgroundThis article evaluates the tree crown characteristics of eight pioneer tree species in the Shorea-Mesua vegetation type (an aseasonal, mixed dipterocarp forest) around the Sinharaja World Heritage Forest Reserve in southwest Sri Lanka. Research Goals & MethodsThe crown surface area, crown volume, and live crown ratio were measured as well as evaluated for their correlation with tree size classes and disturbance causes.

The Ecophysiology of Pioneer Tree Species in Relation to their Disturbance Ecology in a Wet Lowland Rainforest, Sri LankaBackgroundThis dissertation evaluates pioneers species and their response to light availability and disturbance characteristics in the Shorea-Mesua vegetation type (an aseasonal, mixed dipterocarp forest) around the Sinharaja World Heritage Forest Reserve in southwest Sri Lanka.

Arboles de Centroamerica: un Manual para Extensionistas (Trees of Central America: a Manual for Extentionists)EspañolAntecedentesLos agricultores de Centro América afrontan una compleja realidad que usualmente no es considerada en las iniciativas de manejo sostenible, lo que repercute en la falta de éxito de estas. En un esfuerzo por insertar las necesidades reales de los agricultores a estas actividades, este manual busca cubrir la brecha de información relacionada a especies arbóreas nativas de América Central.

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.

Biodiversity Conservation in Traditional Coffee Systems of MexicoBackgroundThis article discusses the capacity of traditional coffee agroforestry systems for maintaining biodiversity levels. Research Goals & MethodsThe authors describe five coffee plantation systems based on differing vegetational and structural complexity: (1) traditional rustic, (2) traditional polyculture, (3) commercial polyculture, (4) shaded monoculture, and (5) unshaded monoculture.

The Role of Rustic Coffee Plantations in the Conservation of Wild Tree Diversity in the Chinantec Region of MexicobackgroundThis study examines the potential of shade coffee systems to promote native tree diversity across the landscape of southern Mexico. Research Goals & MethodsTwenty-two coffee plantations, representing a range of elevation and age of development, were sampled to assess their species compositions. In total, 45 species (34 tree species) were recorded in the plantations, and 77% of them were native species. Open access copy available |
Performance of an Improved Fallow System in the Peruvian Amazon—Modelling ApproachbackgroundThis research compares the ecological and economic potential of an improved leguminous tree fallow (using Inga edulis) to the traditional grass fallow (dominated by Imperata brasiliensis) in central Peru.

Use of the Amazonian Tree Species Inga edulis for Soil Regeneration and Weed ControlbackgroundThis article presents research on leguminous tree-based fallows using Inga edulis in Peru. Research Goals & MethodsFour treatments were compared over a period of nearly 3 years: 1) natural fallow, 2) fallow with I. edulis, 3) fallow with I. edulis combined with a cover crop of kudzu (Pueraria phaseoloides), and 4) continuous cropping of cassava.
