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 |

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.

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.
