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.

Can Intensive Management Accelerate the Restoration of Brazil’s Atlantic Forests?

background

This study takes place in the heavily degraded Atlantic Forest region of eastern Brazil, where only 7% of the original forest cover remains. The study tests the question of whether intensive management methods similar to those used to establish fast-growing Eucalyptus plantations could also be applied to restoration of rainforest on former pasture-land dominated by grasses.

Carbon stocks in biomass and soils of woody species fodder banks in the dry tropics of Mexico

background

Fodder banks are a common feature of tropical silvopasture. This study evaluates the C concentration and storage in above- and belowground tree biomass and soils of fodder banks of Leucaena leucocephala, Guazuma ulmifolia, and a combination of the both 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.

Manual of Reforestation and Erosion Control for the Philippines

background

This manual provides a detailed guide to reforestation, including information about species selection, nursery techniques, site preparation and plantation design, weed and fire control, stand improvement and other practical aspects of establishing and managing tree plantations. Additionally, there is a large portion devoted to erosion control, using trees and engineered structures to stabilize slopes and decrease the velocity of water runoff.

Exotic Trees as Nurse-Trees for the Regeneration of Natural Tropical Forests

Background

This article challenges widely-held views that the presence of exotic tree plantations in the tropics harm the environment. Through collecting evidence from experiences in tropical countries, the authors argue that exotic tree canopies exert protective functions - a nurse effect - for the regeneration of natural forest.
