Trade-offs at applying tree nucleation to restore degraded high Andean forests in ColombiaBackgroundThis article recognizes applied nucleation as a forest restoration strategy in many low to mid altitude forests and aims to compare applied nucleation to passive regeneration at high altitude forests. Applied nucleation is successful at accelerating the speed of forest regeneration, improving soil conditions, and shading out invasive species in many low-mid altitude forests of the neotropics. There are gaps in the literature about the performance of applied nucleation in other tropical regions as well as high attitude tropical forests. Available with subscription or purchase |
Comportamiento de las especies y preferencias de los productores. Plantaciones forestales en Costa Rica y Nicaragua (Species behavior and farmers' preferences. Forest plantations in Costa Rica and Nicaragua)EspañolantecedentesLos autores estudiaron plantaciones comerciales en 112 fincas de productores forestales, en el Cantón de Sarapiquí, Costa Rica y el Departamento de Carazo, Nicaragua. objetivos y metodologíaEl trabajo realiza un inventario de las plantaciones forestales en todas las fincas estudiadas. Las variables evaluadas incluyen: supervivencia, dap, altura total, forma y sanidad de los árboles. Open access copy available |
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.

Foliar herbivory and leaf traits of five native tree species in a young plantation of Central PanamaBackgroundTimber 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. Open access copy available |
Reforestation with Native Species in the Dry Lands of PanamaBACKGROUNDNatural 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 SalvadorbackgroundConservation 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 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.
