Native Species: A Resource for the Diversification of Forestry Production in the Lowland Humid Tropics

background

This research evaluates the success of native species for reforestation plantings in Costa Rica in comparison with exotic species.

Research Goals & Methods

At La Selva Biological Station, 80 species were planted in mixed stands of 8-12 species between 1987 and 1990. Growth characteristics and form for timber quality were collected for each species at 3 and 6 years after planting.

Impacts of Herbicide Application and Mechanical Cleanings on Growth and Mortality of Two Timber Species in Saccharum spontaneum Grasslands of the Panama Canal Watershed

background

This study evaluates the effectiveness of weed control treatments (herbicide application and mechanical cleanings) in promoting the growth and survival of the exotic tree species Tectona grandis and the native tree species Terminalia amazonia.

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.

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.

Research Goals & Methods

The author looks at genotype environment to evaluate stability of genotypes and genotypes with the ability to perform consistently in multiple site conditions.

Carbon Forestry Project CO2OL Tropical Mix

BACKGROUND

Degraded land, originally forest land, later used for extensive cattle ranching, is reforested with mostly native tree species and gradually converted into mixed forests. The project provides for sustainable timber production and cocoa cultivation; protects biodiversity and restores a healthy forest ecosystem. The  project reforests previously degraded pastureland with a mixture of native tree species to produce fine tropical timber, enrich the soil, save and filter water, sequester carbon, and contribute to the mitigation of climate change.

Growth, carbon sequestration, and management of native tree plantations in humid regions of Costa Rica

Background

The Costa Rican government has provided incentives for reforestation programs since 1986 and initiated a Payment for Environmental Services program in 1996. These incentives yielded native species reforestation programs throughout the country. This study examines growth, carbon sequestration, and management of seven native tree species (Vochysia guatemalensis, Vochysia ferruginea, Hyeronima alchorneoides, Calophyllum brasiliense, Terminalia amazonia, Virola koschnyi, and Dipteryx panamensis) in single-species plantations managed by small landowners.

Biomass Distribution Among Tropical Tree Species Grown Under Differing Regional Climates

background

This study presents results from species selection trials in Panama as part of the PRORENA project, which examined the most effective species and methods for Panamanian government-supported reforestation projects.

research goal & methods

In 2003, 16 native and 2 exotic species were planted in single-species plots with a 3m x 3m spacing of trees at two different sites (one seasonally wet, one more dry). All plots were thinned to 50% of their original density at two years after plantation establishment, and the thinned trees were measured for biomass and biomass partitioning.

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.
