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.

Growth characteristics of some native tree species used in silvopastoral systems in the humid lowlands of Costa Rica

Background

Degraded 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.

Environmental Services of Native Tree Plantations and Agroforestry Systems in Central America

Background

Plantations and agroforestry systems supply wood and environmental services such as carbon sequestration and recovery of biodiversity. At the time of writing (2004), Central American countries were developing systems of payments for environmental services to encourage the development of these systems.

Silvicultural and economic aspects of pure and mixed native tree species plantations on degraded pasturelands in humid Costa Rica

Background

Reforestation of degraded land in tropical regions provides one means of restoring ecosystems and improving rural livelihoods. Most plantations in humid tropical regions are established in pure plots using few species of high commercial value, generally exotics. This study compares growth and economic viability of native trees in pure and mixed plantations on degraded land.

Amelioration of degraded rain forest soils by plantations of native trees

background

While much has been studied about the ability of tree growth to improve degraded soils in temperate zones, less is known about the impacts of tree growth on degraded soils in tropical zones.
