Promoting Biodiversity: Advances in Evaluating Native Species for ReforestationbackgroundThis article describes the design of a long-term species screening trial conducted at La Selva Biological Station in Costa Rica. Research Goals & MethodsGrowth and survivability data is presented for 84 species (17 popular exotics used for timber and 67 little-known local species with timber potential) at 3 years of age.

Growth characteristics of some native tree species used in silvopastoral systems in the humid lowlands of Costa RicaBackgroundDegraded 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. Available with subscription or purchase |
Silvicultural and economic aspects of pure and mixed native tree species plantations on degraded pasturelands in humid Costa RicaBackgroundReforestation 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. Available with subscription or purchase |
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.

Development of the soil macrofauna community under silvopastoral and agrosilvicultural systems in AmazoniaBackgroundThe Brazilian Amazon has experienced extensive land conversion from forests to cattle pasture, many of which now lay abandoned. Agro-forestry serves as one potential solution to this problem and this study examines the re-establishment of a diversified soil macrofauna in order to inform this approach.
