Responses of 20 Native Tree Species to Reforestation Strategies for Abandoned Farmland in PanamaBackgroundIn the tropics, deforestation often leads to unproductive agriculture and results in degraded grasslands. This study seeks to understand why forests fail to regenerate naturally in these ecosystems. Open access copy available |
Promoting Biodiversity: Advances in Evaluating Native Species for ReforestationbackgroundThis article describes the design of a long-term species screening trial conducted at La Selva Biological Station in Costa Rica. Research Goals & MethodsGrowth and survivability data is presented for 84 species (17 popular exotics used for timber and 67 little-known local species with timber potential) at 3 years of age.

Tree Management in the Northwestern Andean Cordillera of PeruBackgroundPeasant communities in the northwestern Andean Cordillera of Peru utilize many indigenous and introduced trees and shrubs to satisfy a variety of material needs. However, forest resources are over-harvested and over-grazed, contributing to soil erosion. This study aims to identify the major tree and shrub species in the region and understand their ecologies and usages, and to recommend priorities for reforestation in the region taking human usage into account.

An Evaluation of Farmers' Experiences Planting Native Trees in Rural Panama: Implications for Reforestation with Native Species in Agricultural LandscapesbackgroundOpen access copy available |
Soil organic matter dynamics during 80 years of reforestation of tropical pasturesBackgroundLand disturbance affects soil physical and chemical properties. Some properties may be recovered over long periods of reforestation. Mosaic-pattern landscapes with shifting usages over time, common in the mountainous tropics, can reveal dynamic soil properties. This study reports on changes in soil carbon over 80 years of secondary forest growth on abandoned pasture over a chronosequence in Puerto Rico. Open access copy available |
Globalization, Forest Resurgence, and Environmental Politics in El SalvadorBackgroundEl Salvador was seen as a classic case study of population growth, deforestation, and loss of biodiversity, yet contemporary studies have not supported these claims. Instead, it has been found that forest cover in El Salvador today is actually greater than previously estimated, including remnant forest, reforested areas, plantations, smallholder and NTFP plantations. This resource explores the potential drivers for this unsuspected reforestation. Open access copy available |
Analysis of the Carbon Sequestration Costs of Afforestation and Reforestation Agroforestry Practices and the Use of Cost Curves to Evaluate their Potential for Implementation of Climate Change MitigationbackgroundThis article analyzes the carbon sequestration costs of agroforestry afforestation/reforestation projects (ARPs) as part of the UN's Clean Development Mechanism by evaluating both economies of scale and opportunity costs that affect total sequestration costs. The study uses an agroforestry project called Scolel Té in Chiapas, Mexico to calculate the average net present value (ANPV) of the project in terms of carbon price and project area.

Scolel'te Plan Vivo ProjectBackgroundStarting with a pilot program in 1994, the Scolel'te Project is one of the longest running projects in the Plan Vivo network. It is an ecosystem services program that focuses primarily on reforestation in the Chiapas region of Mexico. Open access copy available |
Geographic Variation in Tree Growth and Wood Density of Guazuma crinita Mart. in the Peruvian AmazonbackgroundThis research addresses intra-specific variation in the native Peruvian tree species Guazuma crinita, a fast-growing pioneer species and priority timber tree used in reforestation and agroforestry systems. It also evaluates the tree growth and wood density of G. crinita varieties from 11 provenances in the Peruvian Amazon. Available with subscription or purchase |
Cloning of erect, thornless, non-browsed nitrogen fixing trees of Haiti's principal fuelwood species (Prosopis juliflora)BackgroundProsopis juliflora (bayawon in Creole) is a spiny leguminous tree that is used throughout arid regions of Africa, Asia, and the Caribbean for fuelwood and fodder. Due to its genetic diversity, pod protein and carbohydrate content varies widely, suggesting advantages of clonal reproduction. This Haiti-based study tests exotic and native varieties of Prosopis for growth rates. Open access copy available |
Evaluation of 15 Indigenous and Introduced Species for Reforestation and Agroforestry in Northeastern MexicoBackgroundThis article presents the results of a reforestation study in the Sierra Madre Mexico. Available with subscription or purchase |
Facilitating Regeneration of Secondary Forests with the Use of Mixed and Pure Plantations of Indigenous Tree SpeciesbackgroundThis research presents the abundance and diversity of woody species regenerating under tropical plantations (mixed and single-species) and a control of natural regeneration at La Selva Biological Station in the Atlantic humid lowlands of Costa Rica. Available with subscription or purchase |
The Role of Native Species Plantations in Recovery of Understory Woody Diversity in Degraded Pasturelands of Costa RicabackgroundThis study analyzes the understory recruitment success of tropical timber plantations in order to understand biodiversity recovery on degraded lands through the use of fast-growing timber plantations. The study takes place in the Atlantic humid lowlands of Costa Rica. Open access copy available |
Early Woody Invasion Under Tree Plantations in Costa Rica: Implications for Forest RestorationBackgroundThis study evaluates the regeneration of woody plants, the amount of herbaceous cover, and the light conditions in the understory of 3-year-old mixed and single-species plantations in Costa Rica. Available with subscription or purchase |
Influence of Overstory Composition on Understory Colonization by Native Species in Plantations on a Degraded Tropical SitebackgroundThis study evaluates forest understory regeneration in a 4.5 year-old plantation in Puerto Rico. The plantations, established in 1989, were planted on abandoned pasture in mixtures or monocultures of three exotic species: Casuarina equisetifolia, Eucalyptus robusta, and Leucaena leucocephala.

Development of Floristic Diversity in 10-year-old Restoration Forests on a Bauxite Mined Site in AmazoniabackgroundThis article evaluates the diversity of species in a 10-year-old native species plantation in the Para state of Brazil. The study site was mined for bauxite in 1984 and planted in 1985 with 70 species of native forest tree species. Open access copy available |
Biomass Distribution Among Tropical Tree Species Grown Under Differing Regional ClimatesbackgroundThis study presents results from species selection trials in Panama as part of the PRORENA project, which examined the most effective species and methods for Panamanian government-supported reforestation projects.
