Early Species Selection for Tropical Reforestation: A Consideration of StabilitybackgroundThis study describes a screening of timber species planted in abandoned pasture sites to understand the effect of different site conditions on tree growth and to determine the species that grew with the highest variation. Research Goals & MethodsThe author looks at genotype environment to evaluate stability of genotypes and genotypes with the ability to perform consistently in multiple site conditions.

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 |
Early Growth Performance of Native and Introduced Fast Growing Tree Species in Wet to Sub-Humid Climates of the Southern Region of Costa RicabackgroundThe authors present information on the growth of seven-year-old native tree species planted in abandoned pasture with low fertility acidic soils in the southern pacific region of Costa Rica. Research Goals & MethodsThe study evalutes trees in four ecoregions of varying elevation and precipitation. Available with subscription or purchase |
Effect of Nurse Tree Species on Early Growth of Anisoptera marginata Korth. (Dipterocarpaceae) on an Imperata cylindrica (L.) Beauv. Grassland Site in South Kalimantan, IndonesiabackgroundThis study evaluates the survival of Anisoptera marginata, a native dipterocarp species, underplanted in four year old plantations of fast-growing exotics: Acadia crassicarpa, Acacia mangium, Gmelina arborea, Paraserianthes falcataria.

Mangrove reforestation in Vietnam: the effect of sediment physicochemical properties on nutrient cyclingBackgroundMangrove forests depend on unique physicochemical properties found in tidal coastal sites. One of the main reasons why mangrove reforestation fails is due to changes in the sediment properties that occurred under deforestation conditions. The iron sulphides common in mangrove sediments are oxidated to sulphuric acid, drastically lowering the sediment pH. Other changes also take place as nutrients leach. This study assesses the effects of pH and redox potential on phosphorus and nitrogen cycling in reforested mangrove stands in southern Vietnam. Open access copy available |
Survival and Growth of Under-Planted Trees: A Meta-Analysis Across four BiomesbackgroundThis article is a meta-analysis synthesizing the results of survival and growth of under-planted trees in forests in tropical, temperate coastal, boreal, and temperate deciduous forests. Additionally, the survival and growth of these underplanted trees are evaluated according to the silvicultural treatment affecting density of the overstory: uncut, dense shelterwood, intermediate density shelterwood, light density shelterwood, clear cut.

Forest Landscape Restoration in ContextbackgroundThis book chapter describes the need for improved management of reforestation projects and affirms the value of a landscape-based approach. Available with subscription or purchase |
The Bigger Picture: Tropical Forest Change in Context, Concept and PracticebackgroundThis article discusses differing concepts of reforestation between the fields of forest science and land change science. Most data from the field of forest science is small in scale and evaluates growth and production from the perspective of use of wood products. Available with subscription or purchase |
Tropical Forest Transitions and Globalization: Neo-Liberalism, Migration, Tourism, and International Conservation AgendasBackgroundDeforestation is giving way to forest regeneration in some tropical regions. This paper uses two case studies to investigate such ‘forest transitions’ in two biodiversity-rich countries, Costa Rica and Madagascar. Open access copy available |
Forest Transition in Vietnam and Bhutan: Causes and Environmental ImpactsbackgroundThe authors evaluate the history of forest transition Vietnam and Bhutan. Goals & MethodsIn order to determine the change in forest cover in Vietnam, the authors collected all available land cover maps, which were then compared to official government records. Using statistical analysis, they then determined the causes of reforestation in the 1990s. For Bhutan, there was no official data analysis. The authords do provide preliminary findings using available data and literature. Available with subscription or purchase |
