Restoration of dry tropical forests in Central America: A review of pattern and process

Background

Much information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.

Reforestation with Native Species in the Dry Lands of Panama

BACKGROUND

Natural populations of precious timber species in Panama are being overexploited, and some have been registered in the IUCN Red List in recent years. Within the overall framework of natural resource scarcity and mounting effects of climate change, the need for sustainable production of native trees that offer added values of water cycle regulation, soil improvement, and biodiversity conservation is stressed.

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.

Towards recovery of native dry forest in the Colombian Andes: a plantation experiment for ecological restoration

Background

Regeneration of native forest after disturbances, especially in arid and semi-arid regions, often progresses slowly or is arrested at a successional stage. This study evaluates the effectiveness of native tree plantings as a restoration strategy in a semi-arid Andean valley.
