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.

Foliar herbivory and leaf traits of five native tree species in a young plantation of Central Panama

Background

Timber plantations often provide economic incentives for land owners to restore abandoned pastures or agricultural land to forest, yet the threat of insect herbivory can diminish these new plantations and compromise the efforts. This study seeks to understand the extent of these threats on tree plantations in Panama.

Reforestation with Native Species in the Dry Lands of Panama

BACKGROUND

Natural populations of precious timber species in Panama are being overexploited, and some have been registered in the IUCN Red List in recent years. Within the overall framework of natural resource scarcity and mounting effects of climate change, the need for sustainable production of native trees that offer added values of water cycle regulation, soil improvement, and biodiversity conservation is stressed.

Tree biodiversity in farmer cooperatives of a shade coffee landscape in western El Salvador

background

Conservation of tropical biodiversity in agricultural landscapes has become more important as the area covered by natural ecosystems decreases. Understanding the types of biodiversity common in agriculturally managed lands, and involving farmers in conservation planning, is important for regional conservation goals.

Impacts of Native Trees on Tropical Soils: A Study in the Atlantic Lowlands of Costa Rica

background

This article describes the results of a study in Costa Rica that compared the soil fertility in a 2.5 year-old plantation of 6 native tree species, grass pasture, and 20 year-old secondary forest.

Research Goals & Methods

Soil extractable Ca, Mg, K, P, Fe, Mn, Cu and Zn, the pH, exchangeable acidity, organic matter and total N were measured in three plots.

Restoring abandoned pasture land with native tree species in Costa Rica: Effects of exotic grass competition and light

Background

Understanding the early establishment requirements and performance of tropical tree seedlings is essential to ensuring the success of restoration plantings. This study characterizes growth and light requirements of six common neotropical tree species: Pseudosamanea guachapele (Fabaceae), Tabebuia impetiginosa (Bignoniaceae), Ceiba pentandra (Bombacaceae), Pachira quinata (Bombacaceae), Dalbergia retusa (Fabaceae), and Tabebuia rosea (Bignoniaceae).
