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.

Reforestation, coffee and carbon in Sierra Piura, Peru: can carbon financing promote sustainable agriculture?

Background

Previous research has suggested that certain agricultural practices can protect, enhance, and reverse environmental degradation. One way to achieve this beneficial connection can be encouraged is through financial mechanisms, such as payment for ecosystem services. This document examines a similar approach in which carbon revenues drive sustainable coffee agriculture in the Sierra Piura region of Peru.

Species-Rich but Distinct Arbuscular Mycorrhizal Communities in Reforestation Plots on Degraded Pastures and in Neighboring Pristine Tropical Mountain Rain Forest

background

This 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.

Cloudbridge Reforestation Project

background

The mission of the Cloudbridge Reforestation Project is to rebuild a deforested part of tropical cloud forest using native trees to bridge a gap between two mountainside forests.  Local people as well as tree consultants are hired to plant the native species.

Reforestation of Abandoned Pastures: Silvicultural Means to Accelerate Forest Recovery and Biodiversity

Background

Despite the 2736 native tree species in Ecuador, the majority of forestation activities in the country are based on exotic pines and eucalypts. In this book chapter, the authors describe the reason for this neglect being the lack of knowledge on the ecology and silvicultural treatment and the lack of nurseries growing these species.

Growth analysis of nine multipurpose woody legumes native from southern Mexico

Background

Deforestation in Mexico has produced significant soil degradation. Reforestation with native leguminous shrubs and trees can contribute to restoration of soil properties. This study evaluates early growth of nine leguminous tree and shrub species in nursery conditions in an ejido (communal agricultural land) in southern Mexico.

Reforestation of Abandoned Pastures: Seed Ecology of Native Species and Production of Indigenous Plant Material

background

This book chapter provides important considerations for sustainable native species reforestation efforts. The authors suggest that although using native species is more prevalent than ever before, there has been little attention to the provenance of the trees used and the genetic diversity within species.

Evaluation of Andean Alder as a Catalyst for the Recovery of Tropical Cloud Forests in Colombia

background

This study compares the species composition and structural diversity of 30-year-old alder plantations with adjacent, naturally regenerated forests of the same age. The study seeks to determine if alder plantations are an appropriate catalyst for forest regeneration for conserving biological diversity and to determine if the differences between the two forest types are maintained over time.
