Biomass Equations for Tropical Tree Plantations Using Secondary Data from the PhilippinesbackgroundThis study advances models for biomass estimation of tropical forests using equations verified by sampling in Philippines plantations. Evidence-based, site-specific equations for biomass estimation can avoid the need for frequent destructive sampling. Open access copy available |
Restoration of dry tropical forests in Central America: A review of pattern and processBackgroundMuch information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.

Initial Performance and Reforestation Potential of 24 Tropical Tree Species Planted Across a Precipitation Gradient in the Republic of PanamabackgroundThe authors of this study planted trees from 22 native species and two exotic species to use in selection trials testing the growth and survivability of trees in plantations in three different sites. Research Goals & MethodsThe sites were chosen for their precipitation gradient from Soberania National Park (2226mm mean annual rainfall), Los Santos (1946mm rainfall), and Rio Hato (1107mm rainfall). Survival, basal diameter, height, crown diameter and wood volume index (VI) were calculated after two years of growth. Available with subscription or purchase |

Native Species: A Resource for the Diversification of Forestry Production in the Lowland Humid TropicsbackgroundThis research evaluates the success of native species for reforestation plantings in Costa Rica in comparison with exotic species. Research Goals & MethodsAt La Selva Biological Station, 80 species were planted in mixed stands of 8-12 species between 1987 and 1990. Growth characteristics and form for timber quality were collected for each species at 3 and 6 years after planting. Available with subscription or purchase |
A Financial Analysis of Small-Scale Tropical Reforestation with Native Species in Costa RicaBackgroundThis article describes the financial expenses and revenues incurred by the 15th year of a small native species plantation in Costa Rica. research goals & methodsForecasting models incorporate growth patterns, production costs, and wood prices to determine the net present value and internal rate of return for the project.

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.

Effect of Nurse Tree Species on Early Growth of Anisoptera marginata Korth. (Dipterocarpaceae) on an Imperata cylindrica (L.) Beauv. Grassland Site in South Kalimantan, IndonesiabackgroundThis study evaluates the survival of Anisoptera marginata, a native dipterocarp species, underplanted in four year old plantations of fast-growing exotics: Acadia crassicarpa, Acacia mangium, Gmelina arborea, Paraserianthes falcataria.

Biomass Distribution Among Tropical Tree Species Grown Under Differing Regional ClimatesbackgroundThis study presents results from species selection trials in Panama as part of the PRORENA project, which examined the most effective species and methods for Panamanian government-supported reforestation projects. research goal & methodsIn 2003, 16 native and 2 exotic species were planted in single-species plots with a 3m x 3m spacing of trees at two different sites (one seasonally wet, one more dry). All plots were thinned to 50% of their original density at two years after plantation establishment, and the thinned trees were measured for biomass and biomass partitioning.
