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.

Screening trial of 14 tropical hardwoods with an emphasis on species native to Costa Rica: Fourth year resultsBackgroundCommercial forestry plantations have consistently relied on a limitd number of species, often favoring exotic species over native ones. This is mainly due to a lack of information or understanding related to the silviculture of native species plantations. This article uses a long-term experiement site in Costa Rica's La Selva Biological Station to work towards filling this knowledge gap. Available with subscription or purchase |
Canopy development in tropical tree plantations: a comparison of species mixtures and monoculturesBackgroundThe establishment of plantation monocultures has dominated much of the intensive forest management practiced in the humid tropics of the Americas, with most forestry research and practice concentrating on a small number of non-indigenous species. Growing interest exists in modifying these practices both by creating mixed-species plantations and by making greater use of native tree species. Available with subscription or purchase |
Understory Development in Young Cordia alliodora PlantationsbackgroundThis article presents the findings of a study evaluating the biomass and composition of understory plants in 1- and 5- year old plantations at the La Selva Biological Station in Costa Rica.

The Role of Rustic Coffee Plantations in the Conservation of Wild Tree Diversity in the Chinantec Region of MexicobackgroundThis study examines the potential of shade coffee systems to promote native tree diversity across the landscape of southern Mexico. Open access copy available |
Tropical rainforest regeneration in an area degraded by mining in Mato Grosso State, BrazilBackgroundGold mining has been a major cause of environmental degradation in the rainforests in the north of Mato Grosso State, Brazil. Regulations on mining activity are beginning to be developed, including standards for forest recovery methodologies. This study characterizes natural tropical rainforest regeneration in Matupa County, Mato Grosso State, Brazil. 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.
