Facilitating Regeneration of Secondary Forests with the Use of Mixed and Pure Plantations of Indigenous Tree Species

background

This 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.

Scolel'te Plan Vivo Project

Background

Starting 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.

The Lembo System: A Model for Agroforestry in Dipterocarp Forest Ecosystems of East Kalimantan

background

This article describes the Lembo system of agroforestry, a traditional practice by the Dayak people in East Kalimantan, Indonesia. In Lembo gardens, around 127 species of woody plants are cultivated, and up to 40 different species can be found per 0.25 ha 90% of which are trees. In those gardens, there is also a large diversity of wild, uncultivated plants.

Cloning of erect, thornless, non-browsed nitrogen fixing trees of Haiti's principal fuelwood species (Prosopis juliflora)

Background

Prosopis 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.

Restoring tropical diversity: beating the time tax on species loss

Background

Remnant tropical forests are being deforested at approximately the same rates as cleared lands revert to secondary forest, leading to a fragmented or patchwork landscape. Small patches of remnant forest may remain, but these inevitably lose species to local extinction. Despite forestation rates that may appear relatively stable on paper, vegetation matrices are rapidly changing from a diversity of old-growth species to a much smaller number of early-successional and non-native species that dominate natural-regeneration and reforestation sites.

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 Mitigation

background

This 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.

Evaluation of 15 Indigenous and Introduced Species for Reforestation and Agroforestry in Northeastern Mexico

Background

This article presents the results of a reforestation study in the Sierra Madre Mexico.

Research Goals & Methods

Ten native species (Pithecellobium, Prosopis, Helietta, Cordia, and Acacia spp.) and five exotic species (Leucaena and Eucalyptus spp.) were raised in a nursery and planted in June of 1984. Measurements took place between 1985 and 1999.

Tree Management in the Northwestern Andean Cordillera of Peru

Background

Peasant 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.
