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.

Screening Trial of 14 Tropical Hardwoods with an Emphasis on Species Native to Costa Rica: Fourth Year Results

Background

A lack of silvicultural information on native timber species in the tropics has contributed to the propogation of fast-growing exotic tree species in reforestation efforts. The plantations evaluated at the La Selva Biological Station in Costa Rica were considered marginal lands with low input of forest maintenance, reflecting the conditions of many lands that farmers would use for reforestation.

Pure and Mixed Forest Plantations with Native Species of the Dry Tropics of Costa Rica: A Comparison of Growth and Productivity

background

This research monitored the growth and survival of 13 natives species in pure and mixed-species plantations, and compared the results to measurements of T. grandis, an exotic species commonly planted in the area.

The Role of Native Species Plantations in Recovery of Understory Woody Diversity in Degraded Pasturelands of Costa Rica

background

This study analyzes the understory recruitment success of tropical timber plantations in order to understand biodiversity recovery on degraded lands through the use of fast-growing timber plantations. The study takes place in the Atlantic humid lowlands of Costa Rica.

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.

Planting Seedlings in Tree Islands Versus Plantations as a Large-Scale Tropical Forest Restoration Strategy

background

This research compares the growth and mortality of 4 tree species (2 native to Costa Rica and 2 native to northwestern South America) in the reforestation of abandoned agricultural land in Costa Rica.

Early Growth of Native and Exotic Trees Planted on Degraded Tropical Pasture

background

This study describes the potential of two exotic and five native tree species to restore degraded land in Costa Rica.

Research Goals & Methods

Thirty blocks were established over 25 hectares of abandoned cattle pasture and tree height was measured at 3 and 7 years and tree survival was measured after 7 years.

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.

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.
