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.

Early Species Selection for Tropical Reforestation: A Consideration of Stability

background

This study describes a screening of timber species planted in abandoned pasture sites to understand the effect of different site conditions on tree growth and to determine the species that grew with the highest variation.

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.

Early Growth Performance of Native and Introduced Fast Growing Tree Species in Wet to Sub-Humid Climates of the Southern Region of Costa Rica

background

The authors present information on the growth of seven-year-old native tree species planted in abandoned pasture with low fertility acidic soils in the southern pacific region of Costa Rica.

Research Goals & Methods

The study evalutes trees in four ecoregions of varying elevation and precipitation.

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.

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.

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.

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.

Growth in pure and mixed plantations of tree species used in reforesting rural areas of the humid region of Costa Rica, Central America

Background

Despite government incentives in Costa Rica for establishing and maintaining native tree plantations since the 1990s, farmers and small landowners often lack adequate knowledge about plantation management. Yield and rotation periods for each of the ten most common species grown in monoculture have previously been published. This paper compares productivity in monoculture and mixtures at La Selva Biological Station in the Caribbean lowlands of Costa Rica.

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.
