Restauración de Bosques en territorios indígenas de Chiapas: modelos ecológicos y estrategias de acción (Restoration of forests in Indigenous territories of Chiapas: ecological models and action strategies)

Español

Antecedentes

Los bosques montanos del sur de México se han fragmentado severamente y su estructura y composición florística se han visto alteradas debido a la agricultura tradicional y al crecimiento demográfico. En extensas áreas de Chiapas, la restauración forestal no solo es una necesidad urgente, sino que también representa una opción viable para la recuperación de productos y servicios que podrían ser utilizados en el futuro de manera sustentable.

Principles and Practice of Forest Landscape Restoration: Case Studies from the Drylands of Latin America

background

Dryland forests cover nearly 30% of the surface of the earth and are of global importance for biodiversity and human livelihoods.Many dryland forest ecosystems have been destroyed or highly degraded due to unsustainable land-use practices, including livestock ranging, overharvesting, conversion to agriculture, and rapid urban growth. This document provides the results of a study evaluating the application of forest landscape restoration to dryland ecosystems in Latin America.

Woody Plant Diversity and Structure of Shade-Grown-Coffee Plantations in Northern Chiapas, Mexico

background

This article presents research on coffee stand structure and diversity, with data collected from 61 coffee plots in Chiapas, Mexico.

Research Goals & Methods

The following variables were measured: coffee density, slope, plot aspect, the number of individuals of each shade species (divided into 9 diametric classes), number of strata, species use, and presence of woody plant species.

Tree species diversity and vegetation structure in shade coffee farms in Veracruz, Mexico

Background

While some studies have argued that shade coffee enables similar biodiversity to remnant forest fragments, others contest that the ecological functions of shade coffee can be assumed to be the same or that policies promoting shade coffee will also benefit remnant forest fragments. Not all taxa have been thoroughly studied in shade coffee. This study reports on tree species diversity and vegetation structure in shade coffee farms in Veracruz, Mexico.

Biodiversity Conservation in Traditional Coffee Systems of Mexico

Background

This article discusses the capacity of traditional coffee agroforestry systems for maintaining biodiversity levels.

Research Goals & Methods

The authors describe five coffee plantation systems based on differing vegetational and structural complexity: (1) traditional rustic, (2) traditional polyculture, (3) commercial polyculture, (4) shaded monoculture, and (5) unshaded monoculture.

The Role of Rustic Coffee Plantations in the Conservation of Wild Tree Diversity in the Chinantec Region of Mexico

background

This study examines the potential of shade coffee systems to promote native tree diversity across the landscape of southern Mexico.

Research Goals & Methods

Twenty-two coffee plantations, representing a range of elevation and age of development, were sampled to assess their species compositions. In total, 45 species (34 tree species) were recorded in the plantations, and 77% of them were native species.

Coffee yields and soil nutrients under the shades of Inga sp. vs. multiple species in Chiapas, Mexico

Background

The type of canopy structure that provides shade to shade-grown coffee may make a difference in production. While Mexican coffee producers have often sought to replace a natural diverse canopy with Inga latibracteata alone, the benefits of either method for yield and for ease of management have not been adequately studied.
