Screening trial of 14 tropical hardwoods with an emphasis on species native to Costa Rica: Fourth year results

Background

Commercial 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.

Growth of native forest species planted on abandoned pasture land in Costa Rica

Background

Reforestation 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.

Canopy development in tropical tree plantations: a comparison of species mixtures and monocultures

Background

The 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.
