Designing Pest-Suppressive Multistrata Perennial Crop Systems: Shade-Grown Coffee in Central America

background

This paper analyzes opportunities to realize the benefits of the presence microflora and fauna in coffee plantations by considering species selection, complimentary characteristics, density, and spatial arrangement of tree species . This study addresses reducing the presence of pests and pathogens such as  leaf rust, coffee leaf minor, berry borer, and the American leaf spot. The authors hypothesize that for every soil and climate for coffee, a multistrata system creates a micro-environment that can create a complex ecosystem to resist pests as a whole as opposed to a pest-by-pest strategy.

The role of species mixtures in plantation forestry

Background

Forest plantations are increasingly being established around the world, yet many are often monocultures. While the paper recognizes that all plantations are beneficial in terms of restoration, it specifically seeks to explore the advantages of mixed-species plantations.

Growth in pure and mixed plantations of tree species used in reforesting rural areas of the humid region of Costa Rica, Central America

Background

Despite government incentives in Costa Rica for establishing and maintaining native tree plantations since the 1990s, farmers and small landowners often lack adequate knowledge about plantation management. Yield and rotation periods for each of the ten most common species grown in monoculture have previously been published. This paper compares productivity in monoculture and mixtures at La Selva Biological Station in the Caribbean lowlands of Costa Rica.

Influence of Tree cover on Diversity, Carbon Sequestration and Productivity of Cocoa Systems in the Ecuadorian Amazon

Background

This study evaluates the relationship between richness and floristic diversity, carbon storage, ecosystem services, agricultural productivity, and forest use potential under three land use systems in the Ecuadorian Amazon: cocoa-based agroforestry, cocoa monoculture and primary forest. In this region, one of the most important cultivation systems is the “Chakra”, a traditional organic farming production system, mainly practiced by indigenous peoples, that consists of the cultivation of staple crops in combination with commercial valuable species such as cocoa, obtaining multiple benefits.

Foliar herbivory and leaf traits of five native tree species in a young plantation of Central Panama

Background

Timber plantations often provide economic incentives for land owners to restore abandoned pastures or agricultural land to forest, yet the threat of insect herbivory can diminish these new plantations and compromise the efforts. This study seeks to understand the extent of these threats on tree plantations in Panama.

Mangrove restoration without planting

Background

Mangrove planting is the most common method of restoring mangrove forests. However, this approach is not often successful, especially when the causes of mangrove degradation were not removed prior to planting new seedlings or propagules. A successful mangrove restoration project may not necessarily include a planting phase. When the stressors are removed and suitable environmental conditions are present, natural regeneration processes could recover mangroves from degradation.

Designing Mixed Species Tree Plantations for the Tropics: Balancing Ecological Attributes of Species with Landholder Preferences in the Philippines

background

This paper reports on the assessment of forest stands planted as part of the Rainforestation Farming Program and the management of plantations by local landowners regarding the original intent of planting.

Research Goals & Methods

Data was collected beginning 6-11 years after initial plot planting. Forest stands were evaluated for structure and floristic composition. Subsequent measurements were taken in 2008 and 2012.

Habitat Distribution of Dipterocarp Species in the Leyte Cordillera: an Indicator for Species – Site Suitability in Local Reforestation Programs

Background

This article presents the results of a vegetation study in primary forest areas of Leyte, in vicinity of the case study site (near Mt. Pangasugan). It provides information on habitat distribution patterns and elevational ranges of dipterocarp species with the purpose of providing baseline data for ensuring species-site suitability for local reforestation programs.
