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.

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.

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.

Tree regeneration in church forests of Ethiopia: effects of microsites and management

Background

Tree regeneration is severely hampered in the fragmented afromontane forests of northern Ethiopia. Pressures of harvesting and grazing and climactic conditions present challenges to regeneration. This study explores how trees regenerate in remnant forests along the gradient from open field, forest edge to closed sites and canopy gaps inside the forest.
