Growth of native forest species planted on abandoned pasture land in Costa Rica

Background

Reforestation programs in Costa Rica have largely utilized only four tree species. This study tests growth rates and form of eleven additional tree species native to the humid tropics, including five N-fixing species and six non-N-fixing species.

Amelioration of degraded rain forest soils by plantations of native trees

background

While much has been studied about the ability of tree growth to improve degraded soils in temperate zones, less is known about the impacts of tree growth on degraded soils in tropical zones.

Tree species effects on soil properties in experimental plantations in tropical moist forest

Background

Forest soil properties are influenced by the complex interactions of vegetation, soil type, geology, management, and climactic patterns. Tree species can differ in their long-term effects on soils. This study resamples one of the earliest replicated experimental sites at La Selva Biological Station, Costa Rica, used to examine the effects of native tropical tree species on soil properties, to examine longer term effects on soil properties.

Nitrogen-fixing trees inhibit growth of regenerating Costa Rican rainforests

BACKGROUND

Nitrogen fixing plants are the primary source of nitrogen in forests, and it is expected that more nitrogen fixers will bring in faster growth. Hence this study conducted, in a humid tropical rainforest North- East Costa Rica, challenged this notion. The area of study had similar dominant species, with P. macroloba being the most dominant Nitrogen fixer.

Coffee yields and soil nutrients under the shades of Inga sp. vs. multiple species in Chiapas, Mexico

Background

The type of canopy structure that provides shade to shade-grown coffee may make a difference in production. While Mexican coffee producers have often sought to replace a natural diverse canopy with Inga latibracteata alone, the benefits of either method for yield and for ease of management have not been adequately studied.

Hacia una silvicultura sostenible en el trópico seco: el caso de la Finca Piedra Rala, Nicaragua (Towards sustainable silviculture in dry tropical forests: the case of Finca Piedra Rala, Nicaragua)

El autor explica la experiencia de los productores en el manejo racional de pequeñas áreas de bosque tropical seco y analiza como la silvicultura racional tiene una capacidad de regeneración de los bosques naturales poco productivos en la zona del Pacífico de Nicaragua. En la finca estudiada, el bosque es sometido a un sistema de aprovechamiento tradicional, desarrollado como una iniciativa del propietario.
