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.

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.

Restoring rainforest fragments: Survival of mixed-native species seedlings under contrasting site conditions in the Western Ghats, IndiaBackgroundHistorical fragmentation and a current annual deforestation rate of 1.2% in the Western Ghats biodiversity hotspot have resulted in a human-dominated landscape of plantations, agriculture, and developed areas, with embedded rainforest fragments that form biodiversity refuges and animal corridors. This study evaluates restoration efficacy for tropical rainforest under three different site conditions in the Anamalai hills, India. Available with subscription or purchase |
Combinations of trees and crops in the taungya method as applied in ThailandBackgroundIn this article, the authors desribe the 'taungya' methods used in Thailand for reforestation and agroforestry in the 1980s. This method was primarily used under theForest Village Programme, during which landless people were given 1.6 ha of land to reforest and raise their crops. Available with subscription or purchase |
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 |
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 |
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.

A Re-emerging Atlantic Forest? Urbanization, Industrialization and the Forest Transition in Santa Catarina, Southern BrazilbackgroundThe Atlantic Forest region of southern Brazil has experienced rapid urbanization and industrialization in the second half of the 20th century. Trends in other regions of the world might suggest this would lead to increased forest cover in rural areas, however a developing country such as Brazil may present a different scenario.

Afforestation and Forestry Land Allocation in Northern Vietnam: Analysing the Gap Between Policy Intentions and OutcomesbackgroundThis study looks at the policy factors surrounding the government's allocation of farmland for afforestation in northern Vietnam. This study takes place in the context of other large-scale afforestation projects conducted by governments in tropical countries, where land rights and livelihoods of local farmers can be at risk.

The Causes of the Reforestation in VietnambackgroundWood exploitation and agricultural expansion led to large-scale deforestation in Vietnam. Since the mid-1990s, forest cover in many areas has increased both in the form of natural regeneration and tree plantations. Policies such as the 1993 Land Law offered households rights to forestland and tree planting campaigns such as the Five Million Hectare Reforestation Programme made people responsible for owning and protecting forest land.
