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.

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.
