Growth, Yield and Survivability
Growth in pure and mixed plantations of tree species used in reforesting rural areas of the humid region of Costa Rica, Central AmericaBackgroundDespite 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. Open access copy available |
Influence of Tree cover on Diversity, Carbon Sequestration and Productivity of Cocoa Systems in the Ecuadorian AmazonBackgroundThis 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 PanamaBackgroundTimber 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. Open access copy available |
Mangrove restoration without plantingBackgroundMangrove 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. Open access copy available |
Teak (Tectona grandis Linn. f): Its Natural Distribution and Related FactorsbackgroundThis paper provides an introduction to the distribution and growth of teak in its natural habitat in India, Burma, Thailand and Laos. Open access copy available |
Designing Mixed Species Tree Plantations for the Tropics: Balancing Ecological Attributes of Species with Landholder Preferences in the PhilippinesbackgroundThis 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 & MethodsData 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. Open access copy available |
Habitat Distribution of Dipterocarp Species in the Leyte Cordillera: an Indicator for Species – Site Suitability in Local Reforestation ProgramsBackgroundThis 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.

Biodiversity–Productivity Relationships in Small-Scale Mixed-Species Plantations Using Native Species in Leyte Province, PhilippinesbackgroundThe growth of tropical reforestation in recent decades has given rise to a debate between the relative productivity, biodiversity, and general merits of mixed-species vs. single-species plantations. To further investigate the relationship between tree species diversity, productivity, and abiotic factors such as climate and soil, this study investigated the growth of mixed-species plantations in Leyte province in the Philippines. These smallholder plantations were planted in 1992 to meet social, economic, and environmental needs through the Rainforestation Farming system. Open access copy available |
Effects of Dry Tropical Forest Fragmentation on the Reproductive Success and Genetic Structure of the tree Samanea samanbackgroundTropical trees are particularly vulnerable to forest fragmentation due to low population densities and reproductive self-incompatibility. Forest fragmentation is likely to decrease gene flow, increase endogamy, and eventually produce a high differentiation among remnant populations. Available with subscription or purchase |
