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 |
Growth of native forest species planted on abandoned pasture land in Costa RicaBackgroundReforestation programs in Costa Rica have largely utilized only four tree species. This study tests growth rates and form of eleven additional tree species native to the humid tropics, including five N-fixing species and six non-N-fixing species.

Early Species Selection for Tropical Reforestation: A Consideration of StabilitybackgroundThis study describes a screening of timber species planted in abandoned pasture sites to understand the effect of different site conditions on tree growth and to determine the species that grew with the highest variation. Research Goals & MethodsThe author looks at genotype environment to evaluate stability of genotypes and genotypes with the ability to perform consistently in multiple site conditions.

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 |
Early Woody Invasion Under Tree Plantations in Costa Rica: Implications for Forest RestorationBackgroundThis study evaluates the regeneration of woody plants, the amount of herbaceous cover, and the light conditions in the understory of 3-year-old mixed and single-species plantations in Costa Rica. Research Goals & MethodsSingle species plots included the native species Jacaranda copaia and Vochysia guatemalensis. Available with subscription or purchase |
Leaf Litter Decomposition and Mulch Performance from Mixed and Monospecific Plantations of Native Tree Species in Costa RicabackgroundThis research looks at leaf litter decomposition rates and mulch performance of four native tree species in mixed and monospecific plantations at the La Selva Biological Station in Costa Rica. The four species considered were Callophylum brasiliense, Jacaranda copaia, Vochysia guatemalensis, and Strypnodendron microstachyum. The faster the decomposition, the faster the nutrient transfer from the trees into the soils for uptake by other trees or by crops when the leaves are used as mulch.
