Forest Plantations in Costa Rica and Nicaragua: Performance of Species and Preferences of FarmersbackgroundThis paper presents data on the survival and growth of mixed native and exotic forest plantations established on abandoned pastures in Costa Rica and Nicaragua. The article also includes information on farmer species preference and socioeconomic information. Open access copy available |
Sustaining Tropical Forest Resources: Reforestation of Degraded LandsbackgroundThis government report provides background material on tropical reforestation and discusses techniques to reforest degraded tropical lands. It considers species planting issues such as: native v. exotic species, monoculture v. polyculture, single purpose v. multipurpose trees, and genetic improvement and plant breeding.

The Agroforestree DatabaseAboutThe Agroforestree (AFT) Database was created in 2009 by the World Forestry Centre and provides specifics and selection guides on both native and exotic agroforestry trees. ContentThe database contains information about 600 tree species useful in agrofrorestry. Species descriptions include the tree's characteristics, ecology, native range, management, and agroforestry uses. The database is searchable by country, native or exotics species, products and/or services provided, and by the first letter of the species.

Temporary Storage of Jussara Palm Seeds: Effects of Time, Temperature and Pulp on Germination and VigorbackgroundThe seeds of the jussara palm (Euterpe edulis) are recalcitrant and immediate sowing is not always possible after harvest; hence, research that examines the ability of the seeds to be stored and the effect of this storage on germination proves important.

The Apparent Paradox of Reestablishing Species Richness on Degraded Lands with Tree MonoculturesbackgroundThis article discusses the use of tropical tree plantations as an approach to rehabilitation of degraded landscapes. For extremely degraded sites, the use of plantations may provide the proper shade, microclimate and protection for other species to colonize the understory. Research on the use of plantations in restoration is discussed, with examples primarily from Puerto Rico. Open access copy available |
Growth and effects of thinning of mixed and pure plantations with native trees in humid tropical Costa RicaBackgroundAs reforestation with native tree species gains in popularity, more information about proper management is needed. This study examines the growth and responses to thinning of ten native species in mixed and pure-species plantations in the Caribbean Lowlands of Costa Rica. Open access copy available |
