Screening trial of 14 tropical hardwoods with an emphasis on species native to Costa Rica: Fourth year results

Background

Commercial forestry plantations have consistently relied on a limitd number of species, often favoring exotic species over native ones. This is mainly due to a lack of information or understanding related to the silviculture of native species plantations. This article uses a long-term experiement site in Costa Rica's La Selva Biological Station to work towards filling this knowledge gap.

Growth characteristics of some native tree species used in silvopastoral systems in the humid lowlands of Costa Rica

Background

Degraded pastures established throughout Central America in the latter 20th C are gradually transitioning to silvopasture or secondary forest. Understanding growth characteristics of trees on these lands is important for proper management.

Woody Understory Plant Diversity in Pure and Mixed Native Tree Plantations at La Selva Biological Station, Costa Rica

Background

This study compares the species richness, abundance, and seed disperal method of individuals growing in the understory of native single-species plantations, native mixed-species plantations, and naturally regenerating (non-planted) areas of the La Selva biological station in Costa Rica.

Environmental Services of Native Tree Plantations and Agroforestry Systems in Central America

Background

Plantations and agroforestry systems supply wood and environmental services such as carbon sequestration and recovery of biodiversity. At the time of writing (2004), Central American countries were developing systems of payments for environmental services to encourage the development of these systems.

Growth and effects of thinning of mixed and pure plantations with native trees in humid tropical Costa Rica

Background

As reforestation with native tree species gains in popularity, more information about proper management is needed. This study examines the growth and responses to thinning of ten native species in mixed and pure-species plantations in the Caribbean Lowlands of Costa Rica.

Silvicultural and economic aspects of pure and mixed native tree species plantations on degraded pasturelands in humid Costa Rica

Background

Reforestation of degraded land in tropical regions provides one means of restoring ecosystems and improving rural livelihoods. Most plantations in humid tropical regions are established in pure plots using few species of high commercial value, generally exotics. This study compares growth and economic viability of native trees in pure and mixed plantations on degraded land.

Plantaciones forestales con especies nativas: Una alternativa para la producción de madera y la provisión de servicios ambientales (Native species tree plantations: and alternative for wood production and environmental services)

Se presenta un panorama general del desarrollo de las actividades de plantaciones forestales en Costa Rica, así como algunos resultados de ensayos de rehabilitación de áreas degradadas con especies forestales nativas en la Estación Biológica La Selva. Durante 12 años, se midió anualmente el crecimiento y la producción de biomasa aérea de doce especies nativas en rodales mixtos y puros, como asi también la fertilidad del suelo bajo plantaciones puras de cuatro especies forestales nativas.

Restauración ecológica de bosques tropicales en Costa Rica: efecto de varios modelos en la producción, acumulación y descomposición de hojarasca

 

Español

Antecedentes

Este estudio se llevó a cabo en Coto Brus, y se enfoca en la restauración de paisajes agrícolas fragmentados dentro del Corredor Biológico Amistosa. El mismo es un área prioritaria para la forestería y la conservación en Costa Rica que ha sido degradrada y transformada por la expansión agrícola durante los pasados 50 años, dejando solo un 25% del bosque original.
