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

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. La mezcla de especies mostro la mayor productividad volumétrica, estadísticamente superior a las especies en plantaciones puras. Open access copy available |

Impacts of Native Trees on Tropical Soils: A Study in the Atlantic Lowlands of Costa RicabackgroundThis 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 & MethodsSoil extractable Ca, Mg, K, P, Fe, Mn, Cu and Zn, the pH, exchangeable acidity, organic matter and total N were measured in three plots.

Strategies for the Recovery of Degraded Ecosystems: Experiences from Latin AmericabackgroundThis paper reviews the rehabilitation potential of native species forest plantations in lowland Costa Rica, the Atlantic Forest of Bahia, Brazil, and sub-tropical Argentina. Native species can improve forest regeneration where soils are degraded and where sources of propagules are limited. While most tropical plantations are dominated by exotic species, native trees may be more appropriate because they are better adapted to the local environment, are already familiar to local farmers, and their propagules are locally available.

Forest Plantations in Costa Rica and Nicaragua: Performance of Species and Preferences of FarmersbackgroundThis paper presents data on the survival and growth of mixed native and exotic forest plantations established on abandoned pastures in Costa Rica and Nicaragua. The article also includes information on farmer species preference and socioeconomic information. Open access copy available |
Environmental Services of Native Tree Plantations and Agroforestry Systems in Central AmericaBackgroundPlantations 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.
