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 |
Implications of Country-Level Decisions on the Specification of Crown Cover in the Definition of Forests for Land Area Eligible for Afforestation and Reforestation Activities in the CDMbackgroundOpen access copy available |
Integration of Hyperion Satellite Data and A Household Social Survey to Characterize the Causes and Consequences of Reforestation Patterns in the Northern Ecuadorian AmazonbackgroundThis paper describes reforestation in the Northern Ecuadorian Amazon (NEA) using 2002 remotely sensed Hyperion images and 2001 Ikonos images. Open access copy available |
The Evolution of Reforestation in BrazilbackgroundThis article describes the history of incentives for reforestation in Brazil from the 1970s through 2001. Open access copy available |
The Fate of the Tropical Forest: Carbon or Cattle?backgroundThe Clean Development Mechanism, established by the Kyoto Protocol, includes small-scale afforestation and reforestation projects as a means for participating developed countries to receive credit for emission redcutions.

On the Restoration of High Diversity Forests: 30 years of Experience in the Brazilian Atlantic ForestbackgroundOpen access copy available |
Tree planting by small producers in the tropics: A comparative study of Brazil and PanamaBackgroundForest regrowth is a widespread phenomenon across the tropical forest latitudes. Such reforestation takes place in the wake of land abandonment, occurs cyclically in a rotational agricultural system, and may result from the deliberate planting of trees by farmers. Although less extensive than successional forest regeneration, tree planting by small farmers can have potentially important environmental impacts at both the site and global scale.

Methods of Facilitating Reforestation of Tropical Degraded Land with the Native Timber Tree, Terminalia amazoniabackgroundIn tropical dry regions, like Costa Rica, it is critical to reforest degraded farms in order to reduce erosion and increase soil fertility. This paper explores the results of an 8-year long experiment in Southern Costa Rica that sought to identify ways to reforest such land economically. Available with subscription or purchase |
Determinants for Successful Reforestation of Abandoned Pastures in the Andes: Soil Conditions and Vegetation CoverBackgroundThis article compares the growth of native and exotic species seedlings planted in abandoned pasture and among brachen ferns and shrubs in Andean Ecuador over three years. Available with subscription or purchase |
Soil compaction and topsoil removal effects on soil properties and seedling growth in Amazonian EcuadorBackgroundSoil properties affect plant growth including during germination and establishment. Topsoil loss, nutrient loss, and compaction due to industrial activity in forest may impact forest regeneration. This study reports on soil properties and seedling growth following topsoil removal in Amazonian Ecuador. Available with subscription or purchase |
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. Available with subscription or purchase |
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 |
Root architecture and allocation patterns of eight native tropical species with different successional status used in open-grown mixed plantations in PanamaBackgroundWhile an increasing number of native tropical trees are under study for reforestation and commercial plantations, the majority of studies on trees in the tropics have concentrated on the aboveground aspects of tree growth. This study investigates biomass allocation and root architecture of eight tropical species with different successional status. Open access copy available |
Carbon Sequestration and Plant Community Dynamics Following Reforestation of Tropical PastureBackgroundConversion of abandoned cattle pasture to secondary forest in the tropics is a potential means to increase carbon sequestration as well as to enhance local biodiversity. This study uses data from a long-term tropical reforestation project – Luquillo Experimental Forest in Puerto Rico – to estimate rates of above- and belowground carbon sequestration. Open access copy available |
Species-Rich but Distinct Arbuscular Mycorrhizal Communities in Reforestation Plots on Degraded Pastures and in Neighboring Pristine Tropical Mountain Rain ForestbackgroundThis study compares the arbuscular mycorrhizal fungi (AMF) of 4 native species saplings growing in three types of fire-degraded pasture (recently abandoned, bracken covered, and shrub covered pasture) to the AMF richness and composition of 30 adult tree species in neighboring primary forest. Open access copy available |
Between and Within-Site Comparisons of Structural and Physiological Characteristics and Foliar Nutrient Content of 14 Tree Species at a Wet, Fertile Site and a Dry, Infertile Site in PanamabackgroundAvailable with subscription or purchase |
Impacts of Herbicide Application and Mechanical Cleanings on Growth and Mortality of Two Timber Species in Saccharum spontaneum Grasslands of the Panama Canal WatershedbackgroundThis study evaluates the effectiveness of weed control treatments (herbicide application and mechanical cleanings) in promoting the growth and survival of the exotic tree species Tectona grandis and the native tree species Terminalia amazonia. Available with subscription or purchase |
Growth of native forest species planted on abandoned pasture land in Costa RicaBackgroundReforestation programs in Costa Rica have largely utilized only four tree species. This study tests growth rates and form of eleven additional tree species native to the humid tropics, including five N-fixing species and six non-N-fixing species.

A Financial Analysis of Small-Scale Tropical Reforestation with Native Species in Costa RicaBackgroundThis article describes the financial expenses and revenues incurred by the 15th year of a small native species plantation in Costa Rica. research goals & methodsForecasting models incorporate growth patterns, production costs, and wood prices to determine the net present value and internal rate of return for the project.
