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.

The Agua Salud Project, Central Panama

Background

The Agua Salud Project is located in the watershed that includes and surrounds the Panama Canal, an engineering feat that largely relies on natural hydrological systems. Much of this watershed has been deforested, thus an official policy has been put into place to reforest and regain ecosystem services. This project seeks to utilize the globalize role of the canal to bring attention to the ecosystem services of the region.

Local and Regional Environmental Variation Influences the Growth of Tropical Trees in Selection Trials in the Republic of Panama

background

This study evaluates the effect of varying site conditions on the basal area of 21 neotropical and 2 exotic tree species at three different sites in Panama.

Barriers to Lowland Tropical Forest Restoration in the Sierra Nevada de Santa Marta, Colombia

Background

This article examines the major barriers to forest restoration in the abandoned pastureland surrounding three forest fragments  in the Rio Rancheria watershed of the Sierra Nevada de Santa Marta in Colombia. These barriers include: seed source, seed predation, competition from grasses, microclimate, soil quality, and fire.

Applying Indigenous Knowledge to the Restoration of Degraded Tropical Rain Forest Clearings Dominated by Bracken Fern

background

The indigenous Lacandon Maya people of southern Mexico use a rotational agriculture system known in Spanish as the milpa for production of maize and other crops. This system rotates production to different plots, allowing the forest and soil to recover in the fallow years between production periods. In some cases, the Lacandon people actively manage forest recovery, sowing Balsa trees to prevent plots from being taken over by the invasive Bracken fern.

Responses of Transplanted Native Tree Species to Invasive Alien Grass Removals in an Abandoned Cattle Pasture in the Lacandon Region, Mexico

background

This study measures the response of 16 native tree species to manual invasive grass removal treatments, for cost-effective regeneration of tropical forest on abandoned cattle pasture in the Lacandon region of Chiapas, southeast Mexico.

Combinations of trees and crops in the taungya method as applied in Thailand

Background

In this article, the authors desribe the 'taungya' methods used in Thailand for reforestation and agroforestry in the 1980s. This method was primarily used under theForest Village Programme, during which landless people were given 1.6 ha of land to reforest and raise their crops.

The Fate of the Tropical Forest: Carbon or Cattle?

background

The Clean Development Mechanism, established by the Kyoto Protocol, includes small-scale afforestation and reforestation projects as a means for participating developed countries to receive credit for emission redcutions.

Carbon Sequestration and Plant Community Dynamics Following Reforestation of Tropical Pasture

Background

Conversion of abandoned cattle pasture to secondary forest in the tropics is a potential means to increase carbon sequestration as well as to enhance local biodiversity. This study uses data from a long-term tropical reforestation project – Luquillo Experimental Forest in Puerto Rico – to estimate rates of above- and belowground carbon sequestration.

Impacts of Herbicide Application and Mechanical Cleanings on Growth and Mortality of Two Timber Species in Saccharum spontaneum Grasslands of the Panama Canal Watershed

background

This study evaluates the effectiveness of weed control treatments (herbicide application and mechanical cleanings) in promoting the growth and survival of the exotic tree species Tectona grandis and the native tree species Terminalia amazonia.

Can Native Tree Species Plantations in Panama Compete with Teak Plantations? An Economic Estimation

background

Panama has high rates of primary forest conversion, resulting in depleted timber resources. In response, the timber plantation industry is growing to meet demand, often with non-native species. This study compares the economic feasibility of using native tree species vs non-native species for plantation forestry.
